These are some quick notes to fix some of the major issues quickly.

The Elastic Search Cluster (ESC) is not responding

To test this issue log into the ESC into the load balancer IP and port 9200, the address should be like below

http://10.10.0.5:9200

At the user prompt enter, the username and password and you should receive a response like below

If not the restart the ESC in this order

Stop all nodes

Start the Data-X nodes

Start the Master-X nodes

Start the Kibana node

Retry to log into ESC

ESC also responds to the 5601 port on the Kibana node; the URL should be like below

http://10.0.0.5:5601/app/kibana#/home?_g=()

This is the Kibana admin portal.

It is important to know that the Kibana admin portal and the cluster data search are not correlated, I mean that the admin portal can be up, but the data nodes are not reachable by the app.

If you are using ESC from another Web app, then try to ping the ESC as below

Enter in the App Service and open the Kudu console

 

Execute a tipping of the internal load balancer

 

If you don’t get any reply then restart the ESC as previous instructions, most of the time it solves the problem.
