# Elasticsearch
## Quick start


### Current client

The currently supported Elasticsearch client for .NET ships in the [Elastic.Clients.Elasticsearch](https://www.nuget.org/packages/Elastic.Clients.Elasticsearch) NuGet package. This package and the underlying transport are instrumented with OpenTelemetry native APIs built into .NET. These will be picked up automatically when the [OpenTelemetry Bridge](/elastic/docs-builder/docs/2322/reference/apm/agents/dotnet/config-core#config-opentelemetry-bridge-enabled) feature is enabled.

### Legacy clients

Instrumentation can be enabled for Elasticsearch when using the official Elasticsearch clients, Elasticsearch.Net and Nest, by referencing [`Elastic.Apm.Elasticsearch`](https://www.nuget.org/packages/Elastic.Apm.Elasticsearch) package and passing `ElasticsearchDiagnosticsSubscriber` to the `AddElasticApm` method in case of ASP.NET Core as following
```csharp
app.Services.AddElasticApm(new ElasticsearchDiagnosticsSubscriber());
```

or passing `ElasticsearchDiagnosticsSubscriber` to the `Subscribe` method
```csharp
Agent.Subscribe(new ElasticsearchDiagnosticsSubscriber());
```

Instrumentation listens for activities raised by `Elasticsearch.Net` and `Nest`, creating spans for executed requests.
<important>
  If you’re using `Elasticsearch.Net` and `Nest` 7.10.1 or 7.11.0, upgrade to at least 7.11.1 which fixes a bug in span capturing.
