Or add the coordinates to your existing project:

    <artifactId>camel-quarkus-micrometer</artifactId>
</dependency>

[id="extensions-micrometer-usage"]
== Usage
This extension leverages https://quarkus.io/guides/micrometer[Quarkus Micrometer]. Quarkus supports a variety of Micrometer metric registry implementations.

Your application should declare the following dependency or  one of the dependencies listed in the https://quarkiverse.github.io/quarkiverse-docs/quarkus-micrometer-registry/dev/index.html[quarkiverse documentation], depending on the monitoring solution you want to work with.

[source,xml]
----
<dependency>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-micrometer-registry-prometheus</artifactId>
</dependency>
----

If no dependency is declared, the Micrometer extension creates a `SimpleMeterRegistry` instance, suitable mainly for testing.


[id="extensions-micrometer-camel-quarkus-limitations"]
== Camel Quarkus limitations

[id="extensions-micrometer-limitations-exposing-micrometer-statistics-in-jmx"]
=== Exposing Micrometer statistics in JMX

Exposing Micrometer statistics in JMX is not available in native mode as `quarkus-micrometer-registry-jmx` does not
have native support at present.

[id="extensions-micrometer-limitations-decrement-header-for-counter-is-ignored-by-prometheus"]
=== Decrement header for Counter is ignored by Prometheus

Prometheus backend ignores negative values during increment of Counter metrics.

[id="extensions-micrometer-limitations-exposing-statistics-in-jmx"]
=== Exposing statistics in JMX ===

In {project-name}, registering a `JmxMeterRegistry` is simplified. Add a dependency for
`io.quarkiverse.micrometer.registry:quarkus-micrometer-registry-jmx` and a `JmxMeterRegistry` will automatically
get created for you.

| Configuration property | Type | Default


a|icon:lock[title=Fixed at build time] [[quarkus-camel-metrics-enable-route-policy]]`link:#quarkus-camel-metrics-enable-route-policy[quarkus.camel.metrics.enable-route-policy]`

Set whether to enable the MicrometerRoutePolicyFactory for capturing metrics on route processing times.
| `boolean`
| `true`

a|icon:lock[title=Fixed at build time] [[quarkus-camel-metrics-enable-message-history]]`link:#quarkus-camel-metrics-enable-message-history[quarkus.camel.metrics.enable-message-history]`

Set whether to enable the MicrometerMessageHistoryFactory for capturing metrics on individual route node processing
times. Depending on the number of configured route nodes, there is the potential to create a large volume of metrics.
Therefore, this option is disabled by default.
| `boolean`
| `false`

a|icon:lock[title=Fixed at build time] [[quarkus-camel-metrics-enable-exchange-event-notifier]]`link:#quarkus-camel-metrics-enable-exchange-event-notifier[quarkus.camel.metrics.enable-exchange-event-notifier]`

Set whether to enable the MicrometerExchangeEventNotifier for capturing metrics on exchange processing times.
| `boolean`
| `true`

a|icon:lock[title=Fixed at build time] [[quarkus-camel-metrics-base-endpoint-uri-exchange-event-notifier]]`link:#quarkus-camel-metrics-base-endpoint-uri-exchange-event-notifier[quarkus.camel.metrics.base-endpoint-uri-exchange-event-notifier]`

Whether to use static or dynamic values for Endpoint Name tags in captured metrics. By default, static values are
used. When using dynamic tags, then a dynamic to (toD) can compute many different endpoint URIs that,
can lead to many tags as the URI is dynamic, so use this with care if setting this option to false.
| `boolean`
| `true`

a|icon:lock[title=Fixed at build time] [[quarkus-camel-metrics-enable-route-event-notifier]]`link:#quarkus-camel-metrics-enable-route-event-notifier[quarkus.camel.metrics.enable-route-event-notifier]`

Set whether to enable the MicrometerRouteEventNotifier for capturing metrics on the total number of routes and total
number of routes running.
| `boolean`
| `true`

a|icon:lock[title=Fixed at build time] [[quarkus-camel-metrics-enable-instrumented-thread-pool-factory]]`link:#quarkus-camel-metrics-enable-instrumented-thread-pool-factory[quarkus.camel.metrics.enable-instrumented-thread-pool-factory]`

Set whether to gather performance information about Camel Thread Pools by injecting an InstrumentedThreadPoolFactory.
| `boolean`
| `false`

a|icon:lock[title=Fixed at build time] [[quarkus-camel-metrics-naming-strategy]]`link:#quarkus-camel-metrics-naming-strategy[quarkus.camel.metrics.naming-strategy]`

Controls the naming style to use for metrics. The available values are `default` and `legacy`. `default` uses the
default Micrometer naming convention. `legacy` uses the legacy camel-case naming style.
| `default`, `legacy`
| `default`

a|icon:lock[title=Fixed at build time] [[quarkus-camel-metrics-route-policy-level]]`link:#quarkus-camel-metrics-route-policy-level[quarkus.camel.metrics.route-policy-level]`

Sets the level of metrics to capture. The available values are `all` ,`context` and `route`. `all` captures metrics
for both the camel context and routes. `route` captures metrics for routes only. `context` captures metrics for the
camel context only.
| `all`, `context`, `route`
| `all`

a|icon:lock[title=Fixed at build time] [[quarkus-camel-metrics-route-policy-exclude-pattern]]`link:#quarkus-camel-metrics-route-policy-exclude-pattern[quarkus.camel.metrics.route-policy-exclude-pattern]`

Comma separated list of route IDs to exclude from metrics collection.
