NAME

       pmtime - time control server for Performance Co-Pilot

SYNOPSIS

       pmtime [-p port]

DESCRIPTION

       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)
       and 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.

       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
       also exit.

ENVIRONMENT

       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.
