Issue/Introduction

After filling up the DX NetOps Console information in the Mediation Manager Web UI for DX NetOps Performance, "update failed and failed to load" error pop-up.

Environment

Mediation Manager 24.3.x

Cause

Out of update in the /etc/hosts file.

By restarting the MM services an error showed up.

$CAMM_HOME/tools/stoptall

$CAMM_HOME/tools/startall

After reviewing the log files under these directories, the root cause of the issue was found:

/opt/CA/CAMM/MC/logs

/opt/CA/CAMM/WEBCAMM/logs

The logs clearly showed that the server, which had been moved to a new network segment, was still referencing the old IP address due to an outdated entry in the /etc/hosts file. As a result, CAMM was attempting to connect to the old IP, which was no longer reachable.

Resolution

After updating the /etc/host file with the correct IP addresses the issue was resolved.
