I’ve tried searching answers in this forum but I haven’t found anything to help me.
How do I increase the SNMP check timeout? An snmpwalk of the monitored device takes about 20 seconds to complete. CheckMK shows me errors like these:
“[agent] Communication failed: timed outCRIT , [snmp] Success, execution time 8.0 sec”
“no unmonitored services found, no vanished services found, no new host labels, [agent] Communication failed: timed outCRIT”
“[agent] Communication failed: timed outCRIT , [snmp] Success, execution time 6.7 sec”
I can’t find where to change the timeouts. I would like to change it to 30 seconds with checks (just for this device) to 5 minutes. All other devices/hosts can remain as they are.
I’m using version 2.1.0p6.cre in case that’s important.
You found the solution, but in case you want to change the SNMP timeouts anyway, this is the right rule for that:
With the default settings checkmk tries six times in total (one attempt and then 5 retries) with a timeout of one second each to gain the data. Overall, this takes approximately 6 seconds. Some devices work better with different settings, e.g. 3 times @ 4 seconds or whatever. It’s a bit of trial and error.
