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.
