Issue/Introduction

We have EPAgents that cannot connect since we applied HF37 to our 10.7 production environment

The clients are reporting

[IntroscopeAgent.IsengardServerConnectionManager] Lost contact with the Introscope Enterprise Manager at daily01.foo.net:5003.

On the MOM (daily01) we see these exceptions starting at the time the fixpack was applied :

11/19/19 12:54:20.747 AM EST [WARN] [ExportReports_Worker-1] [Manager.com.timestock.tess.util.SecurityFilterUtil] Access policy is not enforced due to NoPermissioningRealmException.

These started on the first restart after applying HF37

 

Please advise.

 

Cause

Customer running unsupported release APM 10.2 agents.

Environment

APM 10.7

Resolution

The clients are reporting

[IntroscopeAgent.IsengardServerConnectionManager] Lost contact with the Introscope Enterprise Manager at daily01.foo.net:5003."
-- If "daily01.foo.net:5003" is a MOM, then it's probably OK, as the expected flow is: 1) Agent connect with MOM and receive the connection list. 2) Agent disconnects MOM. 3) Agent connect with a Collector from the connection list.
-- If the EPAgent was not able to connect to a Collector and report metrics, we would need Agent log first to see what's wrong.

"Access policy is not enforced due to NoPermissioningRealmException" is not relevant to this issue.

Customer upgrading EP Agents to 10.7 from 10.2.
