PMTIME(1) General Commands Manual PMTIME(1)
pmtime - time control server for Performance Co-Pilot
pmtime [-D debug] [-V?] [-p port]
pmtime is a graphical user interface for performance monitoring
applications using the PCP infrastructure and requiring
interactive time control.
pmtime is not normally invoked directly by users. Rather, it is
more typical for it to be started by client applications (e.g.
pmchart(1), pmstat(1) or pmval(1)).
There are two modes of interacting with a pmtime process - live
host mode, and historical archive mode. In archive mode the
window presents time controls suitable for manipulating the
archive position, allowing full VCR control to move forwards and
backwards in time at configurable rates and intervals. In live
mode the pmtime window contains the simpler time controls suitable
for live monitoring.
Note that the pmtime window is only made visible when explicitly
requested. Multiple client applications can be connected to a
single pmtime server - when the final client application exits,
pmtime will also exit.
The available command line options are:
-p port, --guiport=port
port is the port number which pmtime will use for
communication with its clients (monitoring applications).
-V, --version
Display version number and exit.
-?, --help
Display usage message and exit.
When a port number is not explicitly requested on the command line
via the -p option, the environment variable PMTIME_PORT can be set
to specify the port number from which available-port probing will
commence when pmtime is searching for a port number to use.
The default starting port number is 43334.
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.
Debugging options specific to pmtime are as follows:
┌────────┬───────────────────────────────────────────────────────┐
│ Option │ Description │
├────────┼───────────────────────────────────────────────────────┤
│ appl0 │ enable internal diagnostics that report all pmtime │
│ │ events, e.g. setting timezone, state changes, │
│ │ interval changes, timescale changes, etc. │
└────────┴───────────────────────────────────────────────────────┘
