Testing Monitoring Across Versions

instructions.md

Test if Monitoring Cluster version X is able to monitor Production Cluster version Y, where X > Y.

1. Download and install Elasticsearch version X. This will be the Monitoring Cluster
2. Download and install Elasticearch version Y. This will be the Production Cluster
3. Download and install Kibana version Y. This will be the Production Kibana
4. Start the Monitoring Cluster:

   bin/elasticsearch -E cluster.name=esmon -E node.name=esmon_1 -E http.port=9400
   

5. Start the Production Cluster:

   bin/elasticsearch -E cluster.name=es1 -E node.name=es1_1
   

6. Start the Production Kibana:

   bin/kibana
   

7. Setup the Production Cluster to export monitoring data to the Monitoring Cluster. In the Production Kibana Console app, run:

   PUT _cluster/settings
   {
     "persistent": {
       "xpack.monitoring.exporters": {
         "mon_cluster": {
           "type": "http",
           "host": [ "localhost:9400"]
         }
       }
     }
   }
   

8. Stop the Production Kibana.
9. Edit the Production Kibana's config/kibana.yml and add:

   xpack.monitoring.elasticsearch.hosts: [ "http://localhost:9400" ]
   

10. Start the Production Kibana.
11. In the Production Kibana's Stack Monitoring app, enable Monitoring.
12. Click around in the Stack Monitoring app to make sure everything works. Make sure that there are no errors in the Kibana server logs either.
