DX NetOps: Data Aggregator AMQ won't start

Products

• Network Observability

Issue/Introduction

While using DX NetOps, you may run into a situation with the Data Aggregator AMQ won't start on port 8581 causing "Unable to Connect" errors from the NetOps Portal, 'Data Sources' page. This could be due to a a problem with the cache partition. To check if this cache issue is causing your DA service not to start properly please check your Karaf.log for this below error:

Caused by: java.nio.file.NoSuchFileException: /opt/CAPM/IMDataAggregator/apache-karaf-4.4.6/data/cache/org.eclipse.osgi/187/0/bundleFile

Environment

Dx NetOps PM

Resolution

We want to run "dadaemon clean" to wipe the cache partition:

1. systemctl stop dadaemon

2. /CA/IM/data/IMDataAggregator/scripts/dadaemon clean

3. systemctl start dadaemon

After a minute or so, port 8581 should be listening again and you should be able to test the Data Aggregator data source again.
