Quickstart - getting your ELK Dashboard up

Logging Analytics Dashboards (Kibana is running out of the box on port 30253 - setup indices on "onap*" and file "@timestamp", hit save and navigate to the discover tab to see logs.

Details:

Login to the kibana dashboard on the ONAP host machine (http://staging.onap.org:30253)

$elasticsearch_password: "changeme"

# verify elastic search

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

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

Configuration
search on onap* not log*
change "index name or pattern" to onap* and select a "time filter field name" to @timestamp

Logging Framework Deployment

Triage Log Capture

The ELK stack containers are under the onap-log namespace in the OOM deployment of ONAP.  They should be started by default - if not you can start them manually.

Kibana is on port 30253, Elasticsearch is on port 30254

...

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.
