PMJSON(1)                General Commands Manual                PMJSON(1)

NAME         top

       pmjson - Performance Co-Pilot JSON dumping utility

SYNOPSIS         top

       pmjson [-mpqyV?]  [-D debug] [-i infile] [-o outfile]

DESCRIPTION         top

       pmjson is used to manipulate JSON (JavaScript Object Notation)
       formatted text used in the Performance Co-Pilot (PCP toolkit).  It
       can produce minimal and human readable output formats when it is
       supplied with valid JSON input.

OPTIONS         top

       The available command line options are:

       -i infile, --in=infile
            JSON formatted input infile - path to a file from which input
            should be read.  If this option is omitted, then pmjson will
            read from the standard input stream.

       -m, --minimal
            Produce JSON output with all superfluous whitespace removed
            from the resulting JSON string.

       -o outfile, --out=outfile
            Formatted output is written to the named outfile.  If this
            option is omitted, then pmjson will write to the standard
            output stream.

       -p, --pretty
            Produce JSON output in a human-readable format.

       -q, --quiet
            Verify the input as valid JSON only, no output is produced.

       -V, --version
            Display version number and exit.

       -y, --yaml
            Produce YAML-like output, a human-readable format with less
            syntactic sugar than JSON.

       -?, --help
            Display usage message and exit.

PCP ENVIRONMENT         top

       Environment variables with the prefix PCP_ are used to
       parameterize the file and directory names used by PCP.  On each
       installation, the file /etc/pcp.conf contains the local values for
       these variables.  The $PCP_CONF variable may be used to specify an
       alternative configuration file, as described in pcp.conf(5).

DEBUGGING OPTIONS         top

       The -D or --debug option enables the output of additional
       diagnostics on stderr to help triage problems, although the
       information is sometimes cryptic and primarily intended to provide
       guidance for developers rather end-users.  debug is a comma
       separated list of debugging options; use pmdbg(1) with the -l
       option to obtain a list of the available debugging options and
       their meaning.
