PIDSTAT(1) User Contributed Perl Documentation PIDSTAT(1)NAMEpidstat - Check the existence of a process on a remote machine
SYNOPSISpidstat [ --help ] [ --host=host ] [ --port=port ] [ --silent ] [
--version ] [ --debug ] [ exists remotepids ]
DESCRIPTION
Pidstat will contact the PID stat daemon (pidstatd, in the IPC::Locker
distribution on CPAN) and perform the requested command(s).
COMMANDS
exists remotepids
Check the existence of a set of process IDs (potentially) on remote
hosts.
Takes a list of remote process IDs. These process IDs are
understood to be on the host specified by "--host" (default is
"localhost"). Alternatively, the host may be overridden by
specifying the process IDs in the form <hostname>:<pid>.
The exit value is 0 if all the requested process IDs exist. The
exit value is 1 if any of the requested process IDs did not exist,
or 2 if any hosts did not have a running daemon. This is roughly
the same as "kill -0 <pid>".
The following works well for shell scripts.
if pidstat exists 3459 host1:4220 host2:9821
then
print "All processes are up"
else
print "One of the processes is down"
fi
