[snmp] Success, Got no information from host

CMK version:
2.0.0p18 (CRE)

OS version:
CentOS 7 for CMK monitoring Aruba Switches (different models)

Error message:
[snmp] Success, Got no information from host, execution time 1.2 sec

Hey all,
we monitor our switches with SNMP. On some switches we receive the above CRIT warnings irregularly but NOT simultaneous. On one specific at regual intervals (~2h with gaps). With the next check everything is fine again.

Currently I have no idea why this is happening and don’t know how to troubleshooting this. I tried to suppress these kind of notification with the event console but I guess this is not the correct way/tool. I dont want to disable notification for this service in general. Is this possible?

Kind regards!
