Issue/Introduction

 

The MOM log contains this

[INFO] [PO:main Mailman 8] [Manager.LoadBalancer] Allowed collectors list {[email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], }@1600897883494 sent to agent 

What could be causing this

 

Cause

 

 

Reviewing the /etc/hosts files of the machines, the hostname had been added to the expression for localhost / 127.0.0.1

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 apm-momserver

 

The Enterprise Manager was using this as a resolved IP from the hostname to send in the list

Environment

Release : 10.7.0

Component : APM Agents

Resolution

 

 

Remove the hostname reference under 127.0.0.1

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
