# NAME: ./check_facts_ldr_procs
|
# PURPOSE: This script is a Nagios Plugin to test FACTS Loader processes
|
# It checks Java if certain Java processes are running or not.
|
# USAGE: ./check_facts_ldr_procs [ -p {proc_list} ] [ -P {pidfile_list} ]
|
# -p {proc_list} = Comma seperated list of Process names to grep for
|
# -P {pidfile_list} = Comma seperated lsit of PID Files. PIDs in files will
|
# be looked for.
|
#
|
# REVISIONS:
|
# Ver Date Author Description
|
# ----- ---------- ---------- ------------------------------------
|
# 2.0 2010-05-07 JD Loots 1. Modified the script for MTN FACTS purposes.
|
# Removed PORT checks.
|
# 2.1 2010-06-02 JD Loots 2. There was a bug in checking PIDs in Linux.
|
# Bug was fixed by introducing a PS variable.
|
# 2.2 2011-05-31 JD Loots 3. Added ability to specify the processes and
|
# PID files on command line (-p and -P) instead
|
# of having the processes specified inside
|
# script. Also removed Warning level procs tests.
|
# 2.3 2011-05-09 JD Loots 4. Added exit to printUsage sub.
