Symptoms

• The Device and Domain fields of a transaction show “Unknown” instead of the correct value.
  

Cause

There are three possible causes:

1. Replacing an existing DPOD installation with a new one for monitoring the same DataPower gateways
2. Adding a new monitored device or domain
3. An issue in DPOD's agents

Resolution

1. If you replaced an existing DPOD installation with a new one, go to Manage → Devices → Gateways, click the gateway and under the “Setup” tab click “Setup Syslog for Device” and “Setup Syslog for all domains”.
   After Syslog Setup is complete, the correct device and domain names will appear in few minutes.
   
2. When adding a new monitored device or domain - wait for 1-2 minutes for DPOD to cache and show the new name.
3. To detect an issue is DPOD's agents, Check System Status Using the Web Console. You may need to restart the agents using Admin Console.
