Hi team, I'm taking a look at Elastic APM.
I've got a question.
How does Elastic APM gather data from ElasticSearch? (I mean monitoring ElasticSearch itself)
I can see Elastic APM has es-restclient-plugins. So I think tracing data to ElasticSearch can be collected through es-restclient-plugins.
But how about instrumenting directly to ElasticSearch(since it's Java).
So. maybe this should be the ultimate question
Do Elastic APM (have a plugin that) instruments ElasticSearch directly? or does it only gather data through es-restclient-plugins
