After upgrading to Network Flow Analysis 21.2.6 to 21.2.10, you may notice that some of your devices may have stopped SNMP polling. This would result in SNMP Refresh / SNMP Discovery failures from the NetOps Portal's Administration: NFA - "Manage Monitoring Page".
This issue would result in Proxies-Wrapper.log messages like this:
INFO | jvm 1 | 2022/04/28 12:50:09 | java.lang.NullPointerException
This is due to the SNMP v3 Profile having Authentication but no Privacy protocol (AuthNoPriv) configured.
Release : 21.2.6 - 21.2.10
Component : NFA
As of now, customers have only reported the issue on versions 21.2.6 and 21.2.8. If a customer needs a patch for 21.2.10, please open a support ticket. This Defect DE535144 will be resolved in NFA 21.2.12.
