NAME

       pmsignal - send a signal to one or more processes

SYNOPSIS

       $PCP_BINADM_DIR/pmsignal [-alnp] [-s signal] [PID ...|name ...]

DESCRIPTION

       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 or
       -p 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 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 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.

OPTIONS

       The available command line options are:

       -a, --all
            Send signal to all named processes.

       -l, --list
            List supported signals.

       -n, --dry-run
            List processes that would be affected.

       -p, --program
            Extract programs from PCP runtime PID files.

       -s signal, --signal=signal
            Specify the signal to send, one of: HUP, USR1, TERM, KILL.

       -?, --help
            Display usage message and exit.

PCP ENVIRONMENT

       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).
