Issue/Introduction

After upgrading to DX Netops Performance Management 20.2.9 or 20.2.10 there is no SNMP data for some devices

We are still seeing reachability statistics which are ICMP based, but not SNMP based metrics.

In the /opt/IMDataCollector/apache-karaf-2.4.3/data/log/Exception.log we see errors similar to:

YYYY-MM-DD HH:MM:SS,###| ERROR | ExceptionLog | A NEW application exception occurred (Key=#################) : Failed to load # items of type {http://im.ca.com/datamgmt}SNMPv3Profile on listener com.ca.im.item.impl.distributed.DistributedItemRepositoryProxyListenerMap$ListenerProxy : no authOid for authProtocol=NONE | (ExceptionLogger.java:99)

Environment

Release : 20.2.9,20.2.10,21.2.1

Component : Polling

Cause

Defect: DE508219

This can be seen when there are one or more SNMP V3 SNMP profiles that are configured for no authentication.

This can cause SNMP profiles that are loaded after that SNMP profile to fail to load.

Resolution

This issue has been fixed in DX Netops Performance Management 21.2.2 and later:

From 21.2.2 Fixed Issues:

Symptom: When SHA256/512 support was added to SNMPv3 authentication protocols, using NoAuthPriv now causes a "java.lang.IllegalArgumentException: no authOid for authProtocol=NONE" in the DC. It fails to load the NoAuthPriv SNMPv3 profiles and subsequent SNMPv3 profiles on DC restart, and can cause all polling to stop for those v3 devices.

Resolution: Removed the exception being thrown when an NoAuthPriv SNMPv3 profile is loaded.

(21.2.2, DE508219, 32694524,32770712)

Additional Information

Workaround:

If you are able to delete the SNMP profiles which are configured for no authentication (No devices are using the profiles) then doing so and restarting the Data Collector(s) will allow the SNMP profiles to load.

If you are not able to delete the noted SNMP profiles, please contact technical support for further guidance.
