SNMP Problems with Checkmk after Upgrade from 7.2.10 to 7.4.9

[taketo]

Did anyone notice also problems with SNMP after the Update to 7.4.9? Before we run this Version there where zero issue with snmp on the gate. Now we got several times a day a SNMP Error xxx.xxx.xxx.xxx: Timeout: No Response from xxx.xxx.xxx.xxx (Exit-Code:1) CRIT.[piggyback] Success (but no data found for this host) Missing monitoring data for all plugins WARN, execution time 6.6 sec.

The wired thing is that it worked most of the time without any issue.

So what is the system generating this alarm?

hi,

i suggested this on reddit, but for the Check_MK try increasing the Service check timeout (Micro Core) to a higher value and also in Setup > SNMP > Timing settings for SNMP access.

the fortigate might answer slower to snmp queries with this version.

also, what version of CMK are you running ?
