Cause

An SNMP OID value can contain multiple records, In this case a specific OID value contained multiple records which caused the SNMP poll to timeout in Aria Operations for Networks.

 

Resolution

To resolve perform the steps below:

SSH to the collector VM where F5 load balancer is integrated, login as 'support' user and modify the fetch record size for SNMP collection in RDB.

1. ub
2. rdb
3. get_policy -cid 0 -ns policy -key snmpPullMinRecSize
4. set_policy -cid 0 -ns policy -key snmpPullMinRecSize  -val 2

Wait for 5-10 mins and check the status of the metric collection under Settings > Accounts and Datasources page, the error should resolve.
