NAME

6       pmtime - time control server for Performance Co-Pilot
7

SYNOPSIS

9       pmtime [-?]  [-p port]
10

DESCRIPTION

12       pmtime  is a graphical user interface for performance monitoring appli‐
13       cations using the PCP infrastructure  and  requiring  interactive  time
14       control.
15
16       pmtime  is  not normally invoked directly by users.  Rather, it is more
17       typical for it to be started by client applications (e.g.   pmchart(1),
18       pmstat(1) or pmval(1)).
19
20       There  are  two  modes of interacting with a pmtime process - live host
21       mode, and historical archive mode.  In archive mode the window presents
22       time  controls suitable for manipulating the archive position, allowing
23       full VCR control to move forwards and backwards in time at configurable
24       rates  and intervals.  In live mode the pmtime window contains the sim‐
25       pler time controls suitable for live monitoring.
26

OPTIONS

28       The arguments to pmtime are as follows:
29
30       -p port, --port=port
31            port is the port number which pmtime will  use  for  communication
32            with its clients (monitoring applications).
33
34       -?, --help
35            Display usage message and exit.
36
37       Note  that  the  pmtime  window  is  only  made visible when explicitly
38       requested.  Multiple client applications can be connected to  a  single
39       pmtime  server  -  when the final client application exits, pmtime will
40       also exit.
41

ENVIRONMENT

43       When a port number is not explicitly requested on the command line  via
44       the -p option, the environment variable PMTIME_PORT can be set to spec‐
45       ify the port number from which  available-port  probing  will  commence
46       when pmtime is searching for a port number to use.
47
48       The default starting port number is 43334.
