I’m trying to monitor a Rittal LCP using an SNMP library sensor but get the following error: “No such Object error #222.” What should I do?
The error message indicates that there is no response to the requested OIDs on the target device here.
Start with a test to confirm that SNMP is working. You can test this with the SNMP Uptime sensor. This sensor type should work for all SNMP devices that are configured correctly. If you can add the sensor, the SNMP is working.
You can also use the Paessler SNMP Tester. Run it on the PRTG probe server, and perform a walk with the OID 1.3.6.1.4.1.2606.21.2.1.1 for the tester against the target device. Configure the Device's IP/Port and SNMP Credentials accordingly.
