Hi guys.
So, by default for SNMP request for CPU Load Avg. Nagios sending SNMP requests and then generating alerts according to the middle count for 1 minute, for 5 minutes, for 15 minutes.
Could someone please help me.
How I can configure Nagios for generating alerts only when cpu load avg > some threshold only during 30 Minutes, not for 1,5,15 minutes.
Thank you in advanced.
use the 15 minutes load and have check interval set at 5 minutes, retry interval 5 minutes, max_check_atempts 4: this should send the first notification after 30 minutes… not the same… but i think it should give the right result…

Thanks very much for this idea.
But I didn’t get it al all.
So, for cpu process I am using the following command:
check_command check_linux_load!netsl!100,9,9!100,100,100
And for this host I am using:
max_check_attempts 3
So, consequently I will receive alert if the threshold will be > 3 after 3*5=15 minutes
But if I want to get it after 30 minutes I need to set max_check to 6,
why you offered to set max_check to 4? because it will be 4*5=20 not 30
Thank you in advanced.
if you are using load 15 you already have a high load for the last 15 minutes… just make out your math and decide how to make it
ohh, i am confused finally
could you please show how it should be look for last 30 minutes for these commands:
check_command check_linux_load!netsl!???,???,???!???,???,???
and
max_check_attempts ???
probably:
check_command check_linux_load!netsl!100,9!,100,100
max_check_attempts 6
or I am wrong?
i don’t know how the command you are using works…
try running it from command line with the --help switch… that should give you enough info.
Keep in mind that linux load does not use percents. for more info see this article as a start: linuxjournal.com/article/9001
