*Since Camel {since}*

The OpenTelemetry component is used for tracing and timing incoming and
outgoing Camel messages using https://opentelemetry.io/[OpenTelemetry].

Events (spans) are captured for incoming and outgoing messages being sent
to/from Camel.

== Configuration

The configuration properties for the OpenTelemetry tracer are:

[width="100%",cols="10%,10%,80%",options="header",]
|=======================================================================
|Option |Default |Description

|excludePatterns |  | Sets exclude pattern(s) that will disable tracing for Camel
messages that matches the pattern. The content is a Set<String> where the key is a pattern. The pattern
uses the rules from Intercept.
|encoding |false| Sets whether the header keys need to be encoded (connector specific) or not. The value is a boolean.
Dashes need for instances to be encoded for JMS property keys.

|=======================================================================


=== Configuration

Include the `camel-opentelemetry` component in your POM, along with any specific dependencies associated with the
chosen OpenTelemetry compliant Tracer.

To explicitly configure OpenTelemetry support, instantiate the `OpenTelemetryTracer` and initialize the camel
context. You can optionally specify a `Tracer`, or alternatively it can be implicitly discovered using the
`Registry`

[source,java]
--------------------------------------------------------------------------------------------------
OpenTelemetryTracer otelTracer = new OpenTelemetryTracer();
// By default it uses the DefaultTracer, but you can override it with a specific OpenTelemetry Tracer implementation.
otelTracer.setTracer(...);
// And then initialize the context
otelTracer.init(camelContext);
