Ingest metrics from ActiveMQ

The OpenTelemetry Collector provides an integration with JMX and ActiveMQ to ingest metrics. The Collector fetches ActiveMQ metrics from JMX. From there the metrics are processed and exported to Lightstep Observability.

To complete the integration, you will:

• Configure the ActiveMQ receiver for the Collector
• Enable the integration by adding it to a pipeline

Prerequisites

• A running ActiveMQ instance
• OpenTelemetry JMX Metric JAR release version 1.9 or later.
• The path to the opentelemetry-jmx-metrics.jar file.
• You’ve configured the Collector to export metric data to Lightstep Observability.

ActiveMQ reporting

The ActiveMQ JMX receiver periodically fetches metrics using a built-in OpenTelemetry helper utilizing a Groovy script. The script is configured to poll both the JMX Agent and the OpenTelemetry JMX Metric Gatherer operation.

For more details regarding configuring the ActiveMQ remote connection, see the official ActiveMQ documentation.

Configure the Collector receiver

In the Collector configuration file, add JVM and ActiveMQ as a receiver and set the following:

• jar_path: The path to the opentelemetry-jmx-metrics.jar file.
• endpoint: The hostname/IP address and port or unix socket file path of the ActiveMQ instance
• target_system: The metrics to collect. Valid values for this integration are jvm and activemq

receivers:

    endpoint: "localhost:9999"
    target_system: jvm,activemq

The OpenTelemetry repo provides additional details about JMX configuration.

Enable the Collector receiver

Once the ActiveMQ receiver is configured, enable it by adding it to one or more pipelines as described in the Collector configuration documentation.

Validate metrics are reporting to Lightstep

You can validate that the metrics are reporting to Lightstep from the Metric details section of the Project Settings page.

1. Open the Project settings page and scroll to the Metric details section.

2. Search for ActiveMQ metric names.

3. If needed, click on the metric to edit the description and how the units are displayed in Lightstep.

Create a dashboard for the metrics

Use the Lightstep Terraform Provider to create a dashboard for the metrics.
