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  LOG-152 - Getting issue details... STATUS  for now you can flip the following dropdown.

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

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.

LOG-230 - Getting issue details... STATUS

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.
