Issue/Introduction

The NFA Console status in NetOps Portal is either showing as 'Stopped' or 'Unreachable' leading to the overall system status to be degraded or Failed.

Referencing KB article 211916 (NetOps NFA System Status unreachable (broadcom.com)), I see a suggestion to check the Watchdog log file.  Below is error displaying on the watchdog log file:

11:51:19 5 - MainWatchdogThread: Watchdog system cycle started
11:51:19 5 - Reporter Status: Starting validate
11:51:20 2 - ReporterProcesses - Error checking SNMP process information :
An item with the same key has already been added.
System.ArgumentException: An item with the same key has already been added.
   at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)
   at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
   at WatchdogMain.DeviceManager.ReporterProcesses..ctor(SnmpProfile profile, IPAddress address)
11:51:20 2 - ReporterProcesses - Error checking SNMP process information :
An item with the same key has already been added.
System.ArgumentException: An item with the same key has already been added.
   at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)
   at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
   at WatchdogMain.DeviceManager.ReporterProcesses..ctor(SnmpProfile profile, IPAddress address)

Environment

NFA All versions

Cause

There were corrupted entries in the reporter_status table in mysql, probably due to multiple NIC cards.

Resolution

Truncated the reporter_status table on the NFA Console machine:

mysql reporter -t -unetqos -pnetqos -e "truncate table reporter_status;"

 

Then recycled the Watchdog service. This will clear out the reporter status, and allow the Watchdog to repopulate it.
