Elasticsearch

Instrumentation can be enabled for Elasticsearch when using the official Elasticsearch clients, Elasticsearch.Net and Nest, by referencing Elastic.Apm.Elasticsearch package and passing ElasticsearchDiagnosticsSubscriber to the UseElasticApm method in case of ASP.NET Core as following

app.UseElasticApm(Configuration, new ElasticsearchDiagnosticsSubscriber()); 

or passing ElasticsearchDiagnosticsSubscriber to the Subscribe method

Agent.Subscribe(new ElasticsearchDiagnosticsSubscriber());

Instrumentation listens for activities raised by Elasticsearch.Net and Nest 7.6.0+, creating spans for executed requests.
