NFA System Status shows service state is Unknown for Console and/or Harvester
SNMP Security Settings not configured to match up with NFA Watchdog Settings.Port 161 or 3308 is blocked by a firewall.
1. On the NFA Console Server and Harvester open Windows Start->Administrative Tools->Services and Right click the Windows SNMP Service and select Properties and Select the Security tab.
2. Make sure the Community String used is the same as the NFA Administration->Watchdog settings (default is public).
LEGACY FLASH GUI:
In NetOps 20.2.x, the Watchdog settings can be found on the CAPC machine under Administration->Data Sources->Network Flow Analysis->Watchdog Settings.
3. Check if the Community String was changed in NFA Database:Log on on NFA Console Server, open the command prompt and run:
4. Check the "SNMP Service" on each machine polled by the Watchdog. Either check "Accept SNMP packets from any host", or add the NFA Console IP and 127.0.0.1 to the “Accept SNMP packets from…” box.
4. Check Microsoft Visual C++ Redistributable installed on NFA Server? see Article Id: 6052 - NFA Admin->System Status Page shows errors from Watchdog Service but configuration is correct
5. Recycle the "NetQoS Reporter/Analyzer Watchdog service" and "CA NFA OData Service" on the NFA Console.
6. Wait a few minutes and refresh the Admin->System Status page again.
7. If the System Status page of NFA is still not showing the actual state of the services, check the \CA\NFA\Reporter\logs\Watchdog*.log for errors.
You also need to make sure ports 161 and 3308 are open between the NFA Console server and the Harvester as the the Watchdog service uses SNMP and MySql to gather information from the Harvester.
