JOURNALCTL(1)                    journalctl                    JOURNALCTL(1)

NAME         top

       journalctl - Query the systemd journal

SYNOPSIS         top

       journalctl [OPTIONS...] [MATCHES...]

DESCRIPTION         top

       journalctl may be used to query the contents of the systemd(1)
       journal as written by systemd-journald.service(8).

       If called without parameters, it will show the full contents of the
       journal, starting with the oldest entry collected.

       If one or more match arguments are passed, the output is filtered
       accordingly. A match is in the format "FIELD=VALUE", e.g.
       "_SYSTEMD_UNIT=httpd.service", referring to the components of a
       structured journal entry. See systemd.journal-fields(7) for a list of
       well-known fields. If multiple matches are specified matching
       different fields, the log entries are filtered by both, i.e. the
       resulting output will show only entries matching all the specified
       matches of this kind. If two matches apply to the same field, then
       they are automatically matched as alternatives, i.e. the resulting
       output will show entries matching any of the specified matches for
       the same field. Finally, the character "+" may appear as a separate
       word between other terms on the command line. This causes all matches
       before and after to be combined in a disjunction (i.e. logical OR).

       It is also possible to filter the entries by specifying an absolute
       file path as an argument. The file path may be a file or a symbolic
       link and the file must exist at the time of the query. If a file path
       refers to an executable binary, an "_EXE=" match for the
       canonicalized binary path is added to the query. If a file path
       refers to an executable script, a "_COMM=" match for the script name
       is added to the query. If a file path refers to a device node,
       "_KERNEL_DEVICE=" matches for the kernel name of the device and for
       each of its ancestor devices is added to the query. Symbolic links
       are dereferenced, kernel names are synthesized, and parent devices
       are identified from the environment at the time of the query. In
       general, a device node is the best proxy for an actual device, as log
       entries do not usually contain fields that identify an actual device.
       For the resulting log entries to be correct for the actual device,
       the relevant parts of the environment at the time the entry was
       logged, in particular the actual device corresponding to the device
       node, must have been the same as those at the time of the query.
       Because device nodes generally change their corresponding devices
       across reboots, specifying a device node path causes the resulting
       entries to be restricted to those from the current boot.

       Additional constraints may be added using options --boot, --unit=,
       etc., to further limit what entries will be shown (logical AND).

       Output is interleaved from all accessible journal files, whether they
       are rotated or currently being written, and regardless of whether
       they belong to the system itself or are accessible user journals.

       The set of journal files which will be used can be modified using the
       --user, --system, --directory, and --file options, see below.

       All users are granted access to their private per-user journals.
       However, by default, only root and users who are members of a few
       special groups are granted access to the system journal and the
       journals of other users. Members of the groups "systemd-journal",
       "adm", and "wheel" can read all journal files. Note that the two
       latter groups traditionally have additional privileges specified by
       the distribution. Members of the "wheel" group can often perform
       administrative tasks.

       The output is paged through less by default, and long lines are
       "truncated" to screen width. The hidden part can be viewed by using
       the left-arrow and right-arrow keys. Paging can be disabled; see the
       --no-pager option and the "Environment" section below.

       When outputting to a tty, lines are colored according to priority:
       lines of level ERROR and higher are colored red; lines of level
       NOTICE and higher are highlighted; lines of level DEBUG are colored
       lighter grey; other lines are displayed normally.

OPTIONS         top

       The following options are understood:

       --no-full, --full, -l
           Ellipsize fields when they do not fit in available columns. The
           default is to show full fields, allowing them to wrap or be
           truncated by the pager, if one is used.

           The old options -l/--full are not useful anymore, except to undo
           --no-full.

       -a, --all
           Show all fields in full, even if they include unprintable
           characters or are very long. By default, fields with unprintable
           characters are abbreviated as "blob data". (Note that the pager
           may escape unprintable characters again.)

       -f, --follow
           Show only the most recent journal entries, and continuously print
           new entries as they are appended to the journal.

       -e, --pager-end
           Immediately jump to the end of the journal inside the implied
           pager tool. This implies -n1000 to guarantee that the pager will
           not buffer logs of unbounded size. This may be overridden with an
           explicit -n with some other numeric value, while -nall will
           disable this cap. Note that this option is only supported for the
           less(1) pager.

       -n, --lines=
           Show the most recent journal events and limit the number of
           events shown. If --follow is used, this option is implied. The
           argument is a positive integer or "all" to disable line limiting.
           The default value is 10 if no argument is given.

       --no-tail
           Show all stored output lines, even in follow mode. Undoes the
           effect of --lines=.

       -r, --reverse
           Reverse output so that the newest entries are displayed first.

       -o, --output=
           Controls the formatting of the journal entries that are shown.
           Takes one of the following options:

           short
               is the default and generates an output that is mostly
               identical to the formatting of classic syslog files, showing
               one line per journal entry.

           short-full
               is very similar, but shows timestamps in the format the
               --since= and --until= options accept. Unlike the timestamp
               information shown in short output mode this mode includes
               weekday, year and timezone information in the output, and is
               locale-independent.

           short-iso
               is very similar, but shows ISO 8601 wallclock timestamps.

           short-iso-precise
               as for short-iso but includes full microsecond precision.

           short-precise
               is very similar, but shows classic syslog timestamps with
               full microsecond precision.

           short-monotonic
               is very similar, but shows monotonic timestamps instead of
               wallclock timestamps.

           short-unix
               is very similar, but shows seconds passed since January 1st
               1970 UTC instead of wallclock timestamps ("UNIX time"). The
               time is shown with microsecond accuracy.

           verbose
               shows the full-structured entry items with all fields.

           export
               serializes the journal into a binary (but mostly text-based)
               stream suitable for backups and network transfer (see Journal
               Export Format[1] for more information). To import the binary
               stream back into native journald format use
               systemd-journal-remote(8).

           json
               formats entries as JSON objects, separated by newline
               characters (see Journal JSON Format[2] for more information).
               Field values are generally encoded as JSON strings, with
               three exceptions:

                1. Fields larger than 4096 bytes are encoded as null values.
                   (This may be turned off by passing --all, but be aware
                   that this may allocate overly long JSON objects.)

                2. Journal entries permit non-unique fields within the same
                   log entry. JSON does not allow non-unique fields within
                   objects. Due to this, if a non-unique field is
                   encountered a JSON array is used as field value, listing
                   all field values as elements.

                3. Fields containing non-printable or non-UTF8 bytes are
                   encoded as arrays containing the raw bytes individually
                   formatted as unsigned numbers.

               Note that this encoding is reversible (with the exception of
               the size limit).

           json-pretty
               formats entries as JSON data structures, but formats them in
               multiple lines in order to make them more readable by humans.

           json-sse
               formats entries as JSON data structures, but wraps them in a
               format suitable for Server-Sent Events[3].

           json-seq
               formats entries as JSON data structures, but prefixes them
               with an ASCII Record Separator character (0x1E) and suffixes
               them with an ASCII Line Feed character (0x0A), in accordance
               with JavaScript Object Notation (JSON) Text Sequences[4]
               ("application/json-seq").

           cat
               generates a very terse output, only showing the actual
               message of each journal entry with no metadata, not even a
               timestamp. If combined with the --output-fields= option will
               output the listed fields for each log record, instead of the
               message.

           with-unit
               similar to short-full, but prefixes the unit and user unit
               names instead of the traditional syslog identifier. Useful
               when using templated instances, as it will include the
               arguments in the unit names.

       --output-fields=
           A comma separated list of the fields which should be included in
           the output. This has an effect only for the output modes which
           would normally show all fields (verbose, export, json,
           json-pretty, json-sse and json-seq), as well as on cat. For the
           former, the "__CURSOR", "__REALTIME_TIMESTAMP",
           "__MONOTONIC_TIMESTAMP", and "_BOOT_ID" fields are always
           printed.

       --utc
           Express time in Coordinated Universal Time (UTC).

       --no-hostname
           Don't show the hostname field of log messages originating from
           the local host. This switch has an effect only on the short
           family of output modes (see above).

           Note: this option does not remove occurrences of the hostname
           from log entries themselves, so it does not prevent the hostname
           from being visible in the logs.

       -x, --catalog
           Augment log lines with explanation texts from the message
           catalog. This will add explanatory help texts to log messages in
           the output where this is available. These short help texts will
           explain the context of an error or log event, possible solutions,
           as well as pointers to support forums, developer documentation,
           and any other relevant manuals. Note that help texts are not
           available for all messages, but only for selected ones. For more
           information on the message catalog, please refer to the Message
           Catalog Developer Documentation[5].

           Note: when attaching journalctl output to bug reports, please do
           not use -x.

       -q, --quiet
           Suppresses all informational messages (i.e. "-- Logs begin at
           ...", "-- Reboot --"), any warning messages regarding
           inaccessible system journals when run as a normal user.

       -m, --merge
           Show entries interleaved from all available journals, including
           remote ones.

       -b [[ID][±offset]|all], --boot[=[ID][±offset]|all]
           Show messages from a specific boot. This will add a match for
           "_BOOT_ID=".

           The argument may be empty, in which case logs for the current
           boot will be shown.

           If the boot ID is omitted, a positive offset will look up the
           boots starting from the beginning of the journal, and an
           equal-or-less-than zero offset will look up boots starting from
           the end of the journal. Thus, 1 means the first boot found in the
           journal in chronological order, 2 the second and so on; while -0
           is the last boot, -1 the boot before last, and so on. An empty
           offset is equivalent to specifying -0, except when the current
           boot is not the last boot (e.g. because --directory was specified
           to look at logs from a different machine).

           If the 32-character ID is specified, it may optionally be
           followed by offset which identifies the boot relative to the one
           given by boot ID. Negative values mean earlier boots and positive
           values mean later boots. If offset is not specified, a value of
           zero is assumed, and the logs for the boot given by ID are shown.

           The special argument all can be used to negate the effect of an
           earlier use of -b.

       --list-boots
           Show a tabular list of boot numbers (relative to the current
           boot), their IDs, and the timestamps of the first and last
           message pertaining to the boot.

       -k, --dmesg
           Show only kernel messages. This implies -b and adds the match
           "_TRANSPORT=kernel".

       -t, --identifier=SYSLOG_IDENTIFIER
           Show messages for the specified syslog identifier
           SYSLOG_IDENTIFIER.

           This parameter can be specified multiple times.

       -u, --unit=UNIT|PATTERN
           Show messages for the specified systemd unit UNIT (such as a
           service unit), or for any of the units matched by PATTERN. If a
           pattern is specified, a list of unit names found in the journal
           is compared with the specified pattern and all that match are
           used. For each unit name, a match is added for messages from the
           unit ("_SYSTEMD_UNIT=UNIT"), along with additional matches for
           messages from systemd and messages about coredumps for the
           specified unit. A match is also added for "_SYSTEMD_SLICE=UNIT",
           such that if the provided UNIT is a systemd.slice(5) unit, all
           logs of children of the slice will be shown.

           This parameter can be specified multiple times.

       --user-unit=
           Show messages for the specified user session unit. This will add
           a match for messages from the unit ("_SYSTEMD_USER_UNIT=" and
           "_UID=") and additional matches for messages from session systemd
           and messages about coredumps for the specified unit. A match is
           also added for "_SYSTEMD_USER_SLICE=UNIT", such that if the
           provided UNIT is a systemd.slice(5) unit, all logs of children of
           the unit will be shown.

           This parameter can be specified multiple times.

       -p, --priority=
           Filter output by message priorities or priority ranges. Takes
           either a single numeric or textual log level (i.e. between
           0/"emerg" and 7/"debug"), or a range of numeric/text log levels
           in the form FROM..TO. The log levels are the usual syslog log
           levels as documented in syslog(3), i.e.  "emerg" (0),
           "alert" (1), "crit" (2), "err" (3), "warning" (4), "notice" (5),
           "info" (6), "debug" (7). If a single log level is specified, all
           messages with this log level or a lower (hence more important)
           log level are shown. If a range is specified, all messages within
           the range are shown, including both the start and the end value
           of the range. This will add "PRIORITY=" matches for the specified
           priorities.

       --facility=
           Filter output by syslog facility. Takes a comma-separated list of
           numbers or facility names. The names are the usual syslog
           facilities as documented in syslog(3).  --facility=help may be
           used to display a list of known facility names and exit.

       -g, --grep=
           Filter output to entries where the MESSAGE= field matches the
           specified regular expression. PERL-compatible regular expressions
           are used, see pcre2pattern(3) for a detailed description of the
           syntax.

           If the pattern is all lowercase, matching is case insensitive.
           Otherwise, matching is case sensitive. This can be overridden
           with the --case-sensitive option, see below.

       --case-sensitive[=BOOLEAN]
           Make pattern matching case sensitive or case insensitive.

       -c, --cursor=
           Start showing entries from the location in the journal specified
           by the passed cursor.

       --cursor-file=FILE
           If FILE exists and contains a cursor, start showing entries after
           this location. Otherwise the show entries according the other
           given options. At the end, write the cursor of the last entry to
           FILE. Use this option to continually read the journal by
           sequentially calling journalctl.

       --after-cursor=
           Start showing entries from the location in the journal after the
           location specified by the passed cursor. The cursor is shown when
           the --show-cursor option is used.

       --show-cursor
           The cursor is shown after the last entry after two dashes:

               -- cursor: s=0639...

           The format of the cursor is private and subject to change.

       -S, --since=, -U, --until=
           Start showing entries on or newer than the specified date, or on
           or older than the specified date, respectively. Date
           specifications should be of the format "2012-10-30 18:17:16". If
           the time part is omitted, "00:00:00" is assumed. If only the
           seconds component is omitted, ":00" is assumed. If the date
           component is omitted, the current day is assumed. Alternatively
           the strings "yesterday", "today", "tomorrow" are understood,
           which refer to 00:00:00 of the day before the current day, the
           current day, or the day after the current day, respectively.
           "now" refers to the current time. Finally, relative times may be
           specified, prefixed with "-" or "+", referring to times before or
           after the current time, respectively. For complete time and date
           specification, see systemd.time(7). Note that --output=short-full
           prints timestamps that follow precisely this format.

       -F, --field=
           Print all possible data values the specified field can take in
           all entries of the journal.

       -N, --fields
           Print all field names currently used in all entries of the
           journal.

       --system, --user
           Show messages from system services and the kernel (with
           --system). Show messages from service of current user (with
           --user). If neither is specified, show all messages that the user
           can see.

       -M, --machine=
           Show messages from a running, local container. Specify a
           container name to connect to.

       -D DIR, --directory=DIR
           Takes a directory path as argument. If specified, journalctl will
           operate on the specified journal directory DIR instead of the
           default runtime and system journal paths.

       --file=GLOB
           Takes a file glob as an argument. If specified, journalctl will
           operate on the specified journal files matching GLOB instead of
           the default runtime and system journal paths. May be specified
           multiple times, in which case files will be suitably interleaved.

       --root=ROOT
           Takes a directory path as an argument. If specified, journalctl
           will operate on journal directories and catalog file hierarchy
           underneath the specified directory instead of the root directory
           (e.g.  --update-catalog will create
           ROOT/var/lib/systemd/catalog/database, and journal files under
           ROOT/run/journal/ or ROOT/var/log/journal/ will be displayed).

       --image=IMAGE
           Takes a path to a disk image file or block device node. If
           specified, journalctl will operate on the file system in the
           indicated disk image. This is similar to --root= but operates on
           file systems stored in disk images or block devices, thus
           providing an easy way to extract log data from disk images. The
           disk image should either contain just a file system or a set of
           file systems within a GPT partition table, following the
           Discoverable Partitions Specification[6]. For further information
           on supported disk images, see systemd-nspawn(1)'s switch of the
           same name.

       --namespace=NAMESPACE
           Takes a journal namespace identifier string as argument. If not
           specified the data collected by the default namespace is shown.
           If specified shows the log data of the specified namespace
           instead. If the namespace is specified as "*" data from all
           namespaces is shown, interleaved. If the namespace identifier is
           prefixed with "+" data from the specified namespace and the
           default namespace is shown, interleaved, but no other. For
           details about journal namespaces see systemd-journald.service(8).

       --header
           Instead of showing journal contents, show internal header
           information of the journal fields accessed.

       --disk-usage
           Shows the current disk usage of all journal files. This shows the
           sum of the disk usage of all archived and active journal files.

       --vacuum-size=, --vacuum-time=, --vacuum-files=
           Removes the oldest archived journal files until the disk space
           they use falls below the specified size (specified with the usual
           "K", "M", "G" and "T" suffixes), or all archived journal files
           contain no data older than the specified timespan (specified with
           the usual "s", "m", "h", "days", "months", "weeks" and "years"
           suffixes), or no more than the specified number of separate
           journal files remain. Note that running --vacuum-size= has only
           an indirect effect on the output shown by --disk-usage, as the
           latter includes active journal files, while the vacuuming
           operation only operates on archived journal files. Similarly,
           --vacuum-files= might not actually reduce the number of journal
           files to below the specified number, as it will not remove active
           journal files.

           --vacuum-size=, --vacuum-time= and --vacuum-files= may be
           combined in a single invocation to enforce any combination of a
           size, a time and a number of files limit on the archived journal
           files. Specifying any of these three parameters as zero is
           equivalent to not enforcing the specific limit, and is thus
           redundant.

           These three switches may also be combined with --rotate into one
           command. If so, all active files are rotated first, and the
           requested vacuuming operation is executed right after. The
           rotation has the effect that all currently active files are
           archived (and potentially new, empty journal files opened as
           replacement), and hence the vacuuming operation has the greatest
           effect as it can take all log data written so far into account.

       --list-catalog [128-bit-ID...]
           List the contents of the message catalog as a table of message
           IDs, plus their short description strings.

           If any 128-bit-IDs are specified, only those entries are shown.

       --dump-catalog [128-bit-ID...]
           Show the contents of the message catalog, with entries separated
           by a line consisting of two dashes and the ID (the format is the
           same as .catalog files).

           If any 128-bit-IDs are specified, only those entries are shown.

       --update-catalog
           Update the message catalog index. This command needs to be
           executed each time new catalog files are installed, removed, or
           updated to rebuild the binary catalog index.

       --setup-keys
           Instead of showing journal contents, generate a new key pair for
           Forward Secure Sealing (FSS). This will generate a sealing key
           and a verification key. The sealing key is stored in the journal
           data directory and shall remain on the host. The verification key
           should be stored externally. Refer to the Seal= option in
           journald.conf(5) for information on Forward Secure Sealing and
           for a link to a refereed scholarly paper detailing the
           cryptographic theory it is based on.

       --force
           When --setup-keys is passed and Forward Secure Sealing (FSS) has
           already been configured, recreate FSS keys.

       --interval=
           Specifies the change interval for the sealing key when generating
           an FSS key pair with --setup-keys. Shorter intervals increase CPU
           consumption but shorten the time range of undetectable journal
           alterations. Defaults to 15min.

       --verify
           Check the journal file for internal consistency. If the file has
           been generated with FSS enabled and the FSS verification key has
           been specified with --verify-key=, authenticity of the journal
           file is verified.

       --verify-key=
           Specifies the FSS verification key to use for the --verify
           operation.

       --sync
           Asks the journal daemon to write all yet unwritten journal data
           to the backing file system and synchronize all journals. This
           call does not return until the synchronization operation is
           complete. This command guarantees that any log messages written
           before its invocation are safely stored on disk at the time it
           returns.

       --flush
           Asks the journal daemon to flush any log data stored in
           /run/log/journal/ into /var/log/journal/, if persistent storage
           is enabled. This call does not return until the operation is
           complete. Note that this call is idempotent: the data is only
           flushed from /run/log/journal/ into /var/log/journal/ once during
           system runtime (but see --relinquish-var below), and this command
           exits cleanly without executing any operation if this has already
           happened. This command effectively guarantees that all data is
           flushed to /var/log/journal/ at the time it returns.

       --relinquish-var
           Asks the journal daemon for the reverse operation to --flush: if
           requested the daemon will write further log data to
           /run/log/journal/ and stops writing to /var/log/journal/. A
           subsequent call to --flush causes the log output to switch back
           to /var/log/journal/, see above.

       --smart-relinquish-var
           Similar to --relinquish-var but executes no operation if the root
           file system and /var/lib/journal/ reside on the same mount point.
           This operation is used during system shutdown in order to make
           the journal daemon stop writing data to /var/log/journal/ in case
           that directory is located on a mount point that needs to be
           unmounted.

       --rotate
           Asks the journal daemon to rotate journal files. This call does
           not return until the rotation operation is complete. Journal file
           rotation has the effect that all currently active journal files
           are marked as archived and renamed, so that they are never
           written to in future. New (empty) journal files are then created
           in their place. This operation may be combined with
           --vacuum-size=, --vacuum-time= and --vacuum-file= into a single
           command, see above.

       -h, --help
           Print a short help text and exit.

       --version
           Print a short version string and exit.

       --no-pager
           Do not pipe output into a pager.

EXIT STATUS         top

       On success, 0 is returned; otherwise, a non-zero failure code is
       returned.

ENVIRONMENT         top

       $SYSTEMD_PAGER
           Pager to use when --no-pager is not given; overrides $PAGER. If
           neither $SYSTEMD_PAGER nor $PAGER are set, a set of well-known
           pager implementations are tried in turn, including less(1) and
           more(1), until one is found. If no pager implementation is
           discovered no pager is invoked. Setting this environment variable
           to an empty string or the value "cat" is equivalent to passing
           --no-pager.

       $SYSTEMD_LESS
           Override the options passed to less (by default "FRSXMK").

           Users might want to change two options in particular:

           K
               This option instructs the pager to exit immediately when
               Ctrl+C is pressed. To allow less to handle Ctrl+C itself to
               switch back to the pager command prompt, unset this option.

               If the value of $SYSTEMD_LESS does not include "K", and the
               pager that is invoked is less, Ctrl+C will be ignored by the
               executable, and needs to be handled by the pager.

           X
               This option instructs the pager to not send termcap
               initialization and deinitialization strings to the terminal.
               It is set by default to allow command output to remain
               visible in the terminal even after the pager exits.
               Nevertheless, this prevents some pager functionality from
               working, in particular paged output cannot be scrolled with
               the mouse.

           See less(1) for more discussion.

       $SYSTEMD_LESSCHARSET
           Override the charset passed to less (by default "utf-8", if the
           invoking terminal is determined to be UTF-8 compatible).

       $SYSTEMD_COLORS
           The value must be a boolean. Controls whether colorized output
           should be generated. This can be specified to override the
           decision that systemd makes based on $TERM and what the console
           is connected to.

       $SYSTEMD_URLIFY
           The value must be a boolean. Controls whether clickable links
           should be generated in the output for terminal emulators
           supporting this. This can be specified to override the decision
           that systemd makes based on $TERM and other conditions.

EXAMPLES         top

       Without arguments, all collected logs are shown unfiltered:

           journalctl

       With one match specified, all entries with a field matching the
       expression are shown:

           journalctl _SYSTEMD_UNIT=avahi-daemon.service
           journalctl _SYSTEMD_CGROUP=/user.slice/user-42.slice/session-c1.scope

       If two different fields are matched, only entries matching both
       expressions at the same time are shown:

           journalctl _SYSTEMD_UNIT=avahi-daemon.service _PID=28097

       If two matches refer to the same field, all entries matching either
       expression are shown:

           journalctl _SYSTEMD_UNIT=avahi-daemon.service _SYSTEMD_UNIT=dbus.service

       If the separator "+" is used, two expressions may be combined in a
       logical OR. The following will show all messages from the Avahi
       service process with the PID 28097 plus all messages from the D-Bus
       service (from any of its processes):

           journalctl _SYSTEMD_UNIT=avahi-daemon.service _PID=28097 + _SYSTEMD_UNIT=dbus.service

       To show all fields emitted by a unit and about the unit, option
       -u/--unit= should be used.  journalctl -u name expands to a complex
       filter similar to

           _SYSTEMD_UNIT=name.service
             + UNIT=name.service _PID=1
             + OBJECT_SYSTEMD_UNIT=name.service _UID=0
             + COREDUMP_UNIT=name.service _UID=0 MESSAGE_ID=fc2e22bc6ee647b6b90729ab34a250b1

       (see systemd.journal-fields(7) for an explanation of those patterns).

       Show all logs generated by the D-Bus executable:

           journalctl /usr/bin/dbus-daemon

       Show all kernel logs from previous boot:

           journalctl -k -b -1

       Show a live log display from a system service apache.service:

           journalctl -f -u apache
