Nagios Script to Check Sessions Behind on a ESA

[DavidWaugh1]

Unfortunately its not currently possible to see if the maximum sessions behind on an ESA easily. This script enables it to be monitored.

Usage:

./check_esa_sessions_behind.sh -w VALUE -c VALUE | -h

This plug-in is used to be alerted when maximum ESA behind sessions is reached

-w/c Sessions behind integer
 To warn when 200 sessions behind and critical when 300 sessions behind
 example: ./check_esa_sessions_behind.sh -w 200 -c 300

 ./check_esa_sessions_behind.sh -w 1 -c 2
CRITICAL behind (>2), Sessions behind: : 26167 |Sessions behind=26167 ;;;
[root@rsaesa ~]# ./check_esa_sessions_behind.sh -w 1 -c 2
CRITICAL behind (>2), Sessions behind: : 35446 |Sessions behind=35446 ;;;
[root@rsaesa ~]# ./check_esa_sessions_behind.sh -w 1 -c 2
CRITICAL behind (>2), Sessions behind: : 35446 |Sessions behind=35446 ;;;

CRITICAL behind (>2), Sessions behind: : 30390 |Sessions behind=30390 ;;;
[root@rsaesa ~]# ./check_esa_sessions_behind.sh -w 1 -c 2
CRITICAL behind (>2), Sessions behind: : 30390 |Sessions behind=30390 ;;;
[root@rsaesa ~]# ./check_esa_sessions_behind.sh -w 1 -c 40000

[root@rsaesa ~]# ./check_esa_sessions_behind.sh -w 1 -c 50000
CRITICAL behind (>50000), Sessions behind: : 50476 |Sessions behind=50476 ;;;
[root@rsaesa ~]# ./check_esa_sessions_behind.sh -w 1 -c 50000
CRITICAL behind (>50000), Sessions behind: : 54902 |Sessions behind=54902 ;;;
[root@rsaesa ~]# ./check_esa_sessions_behind.sh -w 1 -c 50000
CRITICAL behind (>50000), Sessions behind: : 60099 |Sessions behind=60099 ;;;
[root@rsaesa ~]# ./check_esa_sessions_behind.sh -w 1 -c 500000
WARNING behind (>1), Sessions behind: : 60099 |Sessions behind=60099 ;;;

If no values for WARN or CRITICAL are specified then a warning value of 500 and a critical value of 1000 is assumed. These should be adjusted as to what is normal in your environment.
