Hello Andreas,
So the requirement is , we have some Host in which elastic search is there and we need to monitor this and these hosts are added in the Checkmk . we just need to enable the elastic search so that that the number of nodes etc all other services related to elastic search services can be visible along with other services of a host in the Checkmk.
For this we have added the rule following the steps mentioned in the
https://blog.checkmk.com/monitoring-elasticsearch-with-checkmk
Added the rule from “Check state of Elastic Search”
But not getting Elastic search related service in service list in checkmk just like the example given in the above link(https://blog.checkmk.com/monitoring-elasticsearch-with-checkmk)
Not getting like this elastic search related services in our hosts in Checkmk even after creating the rule for elastic search
I have execute the special agent with the “–debug” option to get some error messages if there are errors.
OMD[dev]:~/share/check_mk/agents/special$ ./agent_elasticsearch --debug -P http hostname “cluster_health nodes stats” -p portnumber
<<<check_mk>>>
<<<elasticsearch_cluster_health>>>
<<<check_mk>>>
