If you use EventSentry 3.4 and have a build number older than 68 this error can indicate that either the SNMP check failed due to a blocked port UDP port 161 is required or that the device requires SNMP v3 authentication and this has not been set up yet in EventSentry or is set up incorrectly for the device. Please update your EventSentry...
