Quickstart - getting your ELK Dashboard up

Logging Analytics Dashboards (Kibana)

Enabling the ELK stack

Target the VM in your cluster that is running log-kibana - in the live CD system for example it is usually on http://master3.onap.info:30253/

The index needs to be enabled - this is currently being automated in  for now you can flip the following dropdown.

You will be able to search on logs - separate from also using the kibana dashoards.

Troubleshooting:

Logging Framework Deployment

Triage Log Capture

The following are procedures to determine the state of logs traversing from the container under use via the filebeat, logstash, elasticsearch pipeline.

I would start with the deployment.yaml and verify the filebeat section is the same as other working pods that are listed in the last check I did for pairwise testing.  I would expect logs from for example portal in portal-app and portal-sdk – at least error logs.

After this I would check the logstash service to see if it is receiving logs its port – I’ll add instructions to the wiki.

We can also check the docker pv for the 2 portal containers – the emptydir should be in /var/lib/docker – this is a secondary place we can pickup/verify the logs besides filebeat.
