UpTime check via SNMP

[mpedros]

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?

Code: Select all

[root@localhost libexec]# ./check_snmp -H 192.168.6.5 -C B4x0Syst3msv2 -o sysUpTimeInstance -w @8000
SNMP OK - 4833603 | DISMAN-EVENT-MIB::sysUpTimeInstance=4833603;8000;;
[root@localhost libexec]# ./check_snmp -H 192.168.6.5 -C B4x0Syst3msv2 -o sysUpTimeInstance -w @5000000
SNMP WARNING - *4835102* | DISMAN-EVENT-MIB::sysUpTimeInstance=4835102;5000000;;
[root@localhost libexec]# ./check_snmp -H 192.168.6.5 -C B4x0Syst3msv2 -o sysUpTimeInstance -c @5000000
SNMP CRITICAL - *4836174* | DISMAN-EVENT-MIB::sysUpTimeInstance=4836174;;5000000;

Thank you and have a nice day!

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.
