NAME

6       pmtime - time control server for Performance Co-Pilot

SYNOPSIS

9       pmtime [-V?]  [-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
27       Note that the pmtime window is only made visible  when  explicitly  re‐
28       quested.  Multiple client applications can be connected to a single pm‐
29       time server - when the final client application exits, pmtime will also
30       exit.

OPTIONS

33       The available command line options are:
34
35       -p port, --guiport=port
36            port  is  the  port number which pmtime will use for communication
37            with its clients (monitoring applications).
38
39       -V, --version
40            Display version number and exit.
41
42       -?, --help
43            Display usage message and exit.
44

ENVIRONMENT

46       When a port number is not explicitly requested on the command line  via
47       the -p option, the environment variable PMTIME_PORT can be set to spec‐
48       ify the port number from which  available-port  probing  will  commence
49       when pmtime is searching for a port number to use.
50
51       The default starting port number is 43334.
