=== Diagnostic Source
17+
18+
Elasticsearch.Net and by proxy NEST ship with support for DiagnosticSource and Activity out of the box.
19+
20+
To aid with their discover the topics you can subscribe on and the event names they emit are exposed as
21+
strongly typed strings under `Elasticsearch.Net.Diagnostics.DiagnosticSources`
22+
23+
Subscribing to DiagnosticSources means implementing `IObserver<DiagnosticListener>`
24+
or use `.Subscribe(observer, filter)` to opt in to the correct topic.
25+
26+
Here we choose the more verbose `IObserver<>` implementation.
