Remove Check_MK Check?

[MrD]

CMK version:
Checkmk Raw Edition 2.1.0p9

OS version:
centos 7.9

Error message:

How do I remove the Check_MK Errors for some devices that do not support the agent?

[MrD]

From documentation I would suspect:

This should do it … but still seeing in reporting CRIT error?

For the shown device “10.10.10.10” you have configured “SNMP” and then the “Check_MK” service must exist as all the SNMP queries are done by the “Check_MK” service.
The discovery service says correctly for this device that the SNMP credentials are not correct or the system has no active SNMP.
If you only want a PING on a device you need to also configure the device to not use SNMP.
