Camel Quarkus Micrometer metrics cannot be viewed in Dynatrace

[AshPerera]

I have a Camel Quarkus application, and I can successfully view the Camel metrics at http://localhost:8080/metrics.

I’m using the Prometheus extension to expose the /metrics endpoint, and Micrometer to collect metrics.

My goal is to send these Camel Quarkus metrics to Dynatrace.

pom.xml

        <groupId>io.quarkus</groupId>
        <artifactId>quarkus-micrometer</artifactId>
    </dependency>

        <groupId>io.quarkus</groupId>

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

    <dependency>
      <groupId>io.quarkiverse.micrometer.registry</groupId>
      <artifactId>quarkus-micrometer-registry-otlp</artifactId>
      <version>2.10.0</version>
    </dependency>

The application is containerized using Docker. I have enabled Dynatrace monitoring on the container, and I’m able to see general metrics like Requests, Traces, CPU, and Memory in Dynatrace. To enable this, I have configured three environment variables for the container (in a .env file).

.env file

DT_TENANT=dwqtest
DT_TENANTTOKEN=PF7test
DT_CONNECTION_POINT=https://{environmentid}.live.dynatrace.com:443

Below is my application.properties configuration used to export Camel Micrometer metrics to Dynatrace (built in metrics).

Note : These same properties are also defined in the .env file and used when building the Docker container.

application.properties

quarkus.micrometer.export.prometheus.enabled=true
quarkus.micrometer.export.prometheus.path=/metrics

quarkus.micrometer.binder.http-server.enabled=true 
quarkus.camel.metrics.enable-instrumented-thread-pool-factory=true

quarkus.micrometer.enabled=true
quarkus.camel.metrics.enable=true

# OTLP exporter
quarkus.micrometer.export.otlp.enabled=true
quarkus.micrometer.export.otlp.url=https://{environmentid}.live.dynatrace.com/api/v2/otlp
quarkus.micrometer.export.otlp.headers=Authorization=Api-Token dttest.test
quarkus.micrometer.export.otlp.resource-attributes=service.name=my-camel-app
quarkus.micrometer.export.otlp.step=10s

Despite this, I do not see any of the Camel-specific metrics in Dynatrace in the Metrics or Data Explorer section.

Am I missing any required configuration ?

Do you see any metrics sent using OTLP from your container? Can you validate first if the exporter works and is sending the data you need?

[AshPerera]

Hi Julius, I dont see any metrics sent using OTLP. Didnt see anything in the docker logs. ☹️

I tried the Metrics API to send Metrics to Dyantrace and it worked :

curl -L -X POST 'https://{environmentid}.live.dynatrace.com/api/v2/metrics/ingest' \
-H 'Authorization: Api-Token dt0c01.DFSFSDF324243.TESTSGDGFSDGDSFGDSFGDSGDSFGDSFGD' \
-H 'Content-Type: text/plain' \
--data-raw 'custom.test.metric 123'

Then I was able to see the metrics in the “Metrics” section.

Goal is to send metrics (Camel metrics) from my Camel Quarkus application. That is not working unfortunately.

@AshPerera what I would do first it to double check if it really sends the metrics using otlp.
I’d setup an otel collector and a simple pipeline just to dump the metrics, see Exporters | OpenTelemetry

Hi @Julius_Loman, thanks for the reply.

I was able to resolve my issue.

Camel Quarkus Micrometer metrics can now be viewed in Dynatrace.

I fixed the issue by upgrading Quarkus to the latest version 3.23.4

Thanks.
