check_icmp only warning

[occ]

HI
I would need the check_icmp, when it has 100% of RTA lost, to generate an alert warning instead of an alert critical.
I tried running:
check_icmp -H HOSTADDRESS -w 200.25,100% -c 200,25,101% but continues to generate a critical alert
Is there a way to disable critical?

Hi @occ, thanks for reaching out.

Based on what I'm seeing, it looks like you never want a critical outcome - is that accurate?
Based on the performance data numbers from my own testing, it looks like check_icmp itself is clamping the packet loss numbers so that your critical threshold of 101% is interpreted as 100%.

If you never need a critical check result, my suggestion is to use the negate plugin. The text of the check will still say "CRITICAL", but the check can be reinterpreted as a WARNING result.

Here's the check definition to reassign critical output to warning:

Code: Select all

/usr/local/nagios/libexec/negate -c WARNING /usr/local/nagios/libexec/check_icmp -H HOSTADDRESS -w '200.25,100%' -c '200.25,100%'

Hopefully that helps - let me know if you have any further questions or concerns.

Thanks a lot!!
