Issue/Introduction

No events are seen in CA Performance Center and there are clear Threshold Violations that should be triggering events

Cause

In the /opt/IMDataAggregator/apache-karaf-2.4.3/data/log/karaf.log on the Data Aggregator, we can see that the Data Aggregator is failing to push events to CAPC with an UnknownHostException.

The Data Aggregator host cannot resolve the CA Performance Center host by the hostname/fully qualified domain name in the error message.

Environment

Release : 19.1

Component : IM Reporting / Admin / Configuration

Resolution

The Data Aggregator needs to be able to resolve the hostname/fully qualified domain name of CA Performance Cente as pushed down by CA Performance Center.

A quick way to do this is to make sure there is a correct /etc/hosts entry for CA Performance Center on the Data Aggregator.
