pmsignal — send a signal to one or more processes
$PCP_BINADM_DIR/pmsignal [-alnp] [-s signal] [PID ...|name ...]
pmsignal provides a cross-platform event signalling mechanism for use with tools from the Performance Co-Pilot toolkit. It can be used to send a named signal (only HUP, USR1, TERM, and KILL are accepted) to one or more processes.
The processes are specified directly using PIDs or as program names (with either the -a/--all or -p/--program options). In the all case, the set of all running processes is searched for a basename(1) match on name. In the program case, process identifiers are extracted from files in the $PCP_RUN_DIR directrory where file names are matched on name.pid.
The -n/--dry-run option reports the list of process identifiers that would have been signalled, but no signals are actually sent.
If a signal is not specified, then the TERM signal will be sent. The list of supported signals is reported when using the -l/--list option.
On Linux and UNIX platforms, pmsignal is a simple wrapper around the kill(1) command. On Windows, the is no direct equivalent to this mechanism, and so an alternate mechanism has been implemented - this is only honoured by PCP tools, however, not all Windows utilities.
Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configuration file, as described in pcp.conf(5).
