UpTime check via SNMP

Hi:
I am checking the uptime of a desktop by SNMP and it works correctly.
Code: Select all
[root@localhost libexec]# ./check_snmp -H 192.168.6.5 -C B4x0Syst3msv2 -o sysUpTimeInstance
SNMP OK - 853898 | DISMAN-EVENT-MIB::sysUpTimeInstance=853898
[root@localhost libexec]#
How could I have generated a warning if the value is less than for example "8000 timeticks"? I guess with regular expressions but I do not know how to configure it.
I thank you in advance for the help.

Hi Scott:
Thank you very much for your prompt response, it worked correctly! Do you have any suggestions where I can study these types of expressions for SNMP monitoring?

great!
Here is the resource

This is how official plugins are supposed to work but, many plugins are from the community that may not conform.
