Asset Discovery not listening for agents on designated port

Summary

The Asset Discovery Scanner may not show any traffic on the port designated for listening for Agents.

Body

Issue

The Asset Discovery service is not listening for agents on a designated port

When checking a port for Asset Discovery activity, nothing is returned

In the Asset Discovery Manager application, the CFGUPDATE message includes a line stating "Agent listener port: disabled"

Troubleshooting

  • Verify that customer is using the most up-to-date version of the Scanner software
  • Confirm the Discovery Job is active in TDAdmin
  • Confirm that the Asset Data Provider is configured for the Discovery Job
    • The Agent Listener port is only opened if you have a job that contains an "Agent" data provider
  • Open the discjobs.json file in the Scanner's configuration files (e.g., "C:\Program Files (x86)\TeamDynamix\TeamDynamix PROD Asset Discovery Scanner")
    • Look for the line starting "Methods"
    • If the value for this line is blank (i.e., the line shows "Methods": "[ ]" there are no asset discovery jobs configured for this scanner

Escalation Steps

Collect the following information and escalate to Engineering:

  • All the .log files under the customer's Scanner installation directory (e.g., "C:\Program Files (x86)\TeamDynamix\TeamDynamix PROD Asset Discovery Scanner")
  • All the configuration files under the customer's Scanner installation directory (e.g., "C:\Program Files (x86)\TeamDynamix\TeamDynamix PROD Asset Discovery Scanner")
  • All the configuration files under the customer's Agent installation directory (e.g., "C:\Program Files (x86)\TeamDynamix\TeamDynamix Asset Discovery Agent")
  • Any purple (agent-related) messages in the activity log in the Asset Discovery Manager application
  • IP address(es) of any machines with agents installed which aren't being contacted
  • Scanner ID
  • Discovery Job ID
