Elasticsearch search response time / latency metrics

[jaykb77 (Jay)]

We are trying to use elasticsearch-exporter (GitHub - prometheus-community/elasticsearch_exporter: Elasticsearch stats exporter for Prometheus) for monitoring our clusters(v7.17) and we want to monitor the cluster performance. Especially search/indexing response time/latency.

It looks like we will have to derive this from available metrics, but its not clear for us. Could someone help with what metrics from node exporter can be used for this purpose?

Also, what are the top 5 things to monitor when it comes to an elasticsearch cluster apart from the above.

Exporting Elastic cloud cluster performance stats

Hi @kielni Thanks for the feedback I will pass that on, I agree. (Our self-manged offerings which I am not suggesting you change to have multiple ways to export the Elasticsearch metrics to the monitoring system of your choice, with respect to Cloud offering I think we are still working on it, strangely it takes a little more effort.) Now on to your other questions 1st) I would not try use the the metrics charts under Deployments / [deployment] / Performance, tl;dr they not as reliable as t…

Basically for example, average index latency would be the counter rate of index events divided by the counter rate of index time total.
