Issue/Introduction

Symptoms:

 The tracelog on the DE manager contains an error "Exception: Key not available for node" for an agent

 

Cause: 

The manager is being contacted by the agent but the agent is missing from the typology and the agent cannot be resolved.

 

Resolution:

 Either remove the manager definition from the agentparm.txt file or add the agent to the managers typology.

communication.monitorobject_1=MY_AGENT/AGENTMON1.0/MAIN

 

5.    Remove or comment out the “communication.managerid” lines

6.    Cold start the agent (highly recommended)
