pmtime is a graphical user interface for performance monitoring
applications using the PCP infrastructure and requiring interactive
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)
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
The arguments to pmtime are as follows:
-p port is the port number which pmtime will use for communication
with its clients (monitoring applications).
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
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.
