An internal error has occurred at the agent: “java.lang.IllegalStateException: getAgentSubstitutionMap(“cluster.ClusterName”) == null”

$emcli test_named_credential -cred_names="SEC_RACTEST" -target_name="CLU-RACTEST" -target_type="cluster"

An internal error has occurred at the agent: "java.lang.IllegalStateException: getAgentSubstitutionMap("cluster.CLU-RACTEST") == null". Check the agent's error logs for details.

Run “emctl config agent listtargets”, it shows there is no ‘cluster’ target type listed for any of the monitoring agents.

SOLUTION

From the OEM Console, go to Cluster homepage -> Target Setup -> Monitoring Configuration.
Click on the Update button (no need to make any other changes).

This will push the cluster target details to the agent side.

Then run “emcli test_named_credential” successfully.

$emcli test_named_credential -cred_names="SEC_RACTEST" -target_name="CLU-RACTEST" -target_type="cluster"

Credentials "SEC_RACTEST:SYSMAN" tested successfully
