SNMP - Classify: 0 OIDs for UPS

Sudhakara Redd2 · ‎03-20-2017

Hello Everyone,

I am running discovery for UPS and able to discover few UPS but for most the UPS I am getting SNMP - Classify: 0 OIDs in ECC queue and warning as SNMP probe timed out. Target is either unreachable or there are no valid credentials for it. I gone few blogs, they mentioned I need to MIBs and MID server must be functional and other details too but for MID server is working fine and there is no firewall blocking. I am getting devices that I can see in ECC queue log.

Hi Sudhakar,

By looking at the error it seems you have some connection issues. Its better you can do SNMP walk from your MID Server with some third party utility/software. By that way you can see you are getting respose or not. If you didnt get any response you can go with that error with your Network team. Instead of going with ServiceNow-xml payload if you go with utility response it will be helpful for your network team to understand.

You can get MIB files from the product vendor. it will give you more detailed information about your device. In your case ServiceNow is already discovering some UPS devices with the existing MIB files in ServiceNow. So if you are looking for more information for the device which are already discovered then go for MIB file.

Regards,

Vivek

Based on the impact hit like, helpful, or correct.

Thanks for the update Vivek. Yes I checked with SNMPWALK. I am unable to reach the device and getting "Timeout error". I am working with network team to fix it.

To add to Vivek's response:

You should check with the network team to ensure you have the Community String to communicate with the UPS's you can also search online for the OID's for that device by it's model. So a search of "ACME Brand Model X OID" might provide you a trail to the OID and MIB used for that device. You can then write your own probes for discovery and add a new MIB to your MID servers. Write-ups, for doing both exist on this forum.
