 # Observability [observability]
 
-To observe and measure {{es}} client usage, several client features are provided.
+Several client features help you observe and measure {{es}} client usage. As of version 8.15.0, the JS client provides native support for OpenTelemetry, which allows you to send client usage data to any endpoint that supports OpenTelemetry without having to make any changes to your JavaScript codebase. 
 
-First, as of 8.15.0, the client provides native support for OpenTelemetry, which allows you to send client usage data to any endpoint that supports OpenTelemetry without having to make any changes to your JavaScript codebase.

-Also, rather than providing a default logger, the client offers an event emitter interface to hook into internal events, such as `request` and `response`, allowing you to log the events you care about, or otherwise react to client usage however you might need.
-
-Correlating events can be hard, especially if your applications have a large codebase with many events happening at the same time. To help you with this, the client provides a correlation ID system, and other features.

-All of these observability features are documented below.
+Rather than providing a default logger, the client offers an event emitter interface to hook into internal events, such as `request` and `response`, allowing you to log the events you care about, or otherwise react to client usage however you might need. Because correlating events can be hard, the client provides a correlation ID system, and other features.
 
 ## OpenTelemetry [_opentelemetry]
 
 The client supports OpenTelemetry’s [zero-code instrumentation](https://opentelemetry.io/docs/zero-code/js/) to enable tracking each client request as an [OpenTelemetry span](https://opentelemetry.io/docs/concepts/signals/traces/#spans). These spans follow all of the [semantic OpenTelemetry conventions for {{es}}](https://opentelemetry.io/docs/specs/semconv/database/elasticsearch/) except for `db.query.text`.
 
-To start sending {{es}} trace data to your OpenTelemetry endpoint, follow [OpenTelemetry’s zero-code instrumentation guide](https://opentelemetry.io/docs/zero-code/js/), or the following steps:
-
-1. Install `@opentelemetry/api` and `@opentelemetry/auto-instrumentations-node` as Node.js dependencies
-2. Export the following environment variables with the appropriate values:
-
-    * `OTEL_EXPORTER_OTLP_ENDPOINT`
-    * `OTEL_EXPORTER_OTLP_HEADERS`
-    * `OTEL_RESOURCE_ATTRIBUTES`
-    * `OTEL_SERVICE_NAME`
-
-3. `require` the Node.js auto-instrumentation library at startup:
-
-```
-node --require '@opentelemetry/auto-instrumentations-node/register' index.js
-```
+To start sending {{es}} trace data to your OpenTelemetry endpoint, instrument the client using the [Elastic Distribution of OpenTelemetry (EDOT) JavaScript](elastic-otel-node://reference/edot-node/index.md), or follow [OpenTelemetry’s zero-code instrumentation guide](https://opentelemetry.io/docs/zero-code/js/).
