Configure Apache Kafka® MirrorMaker 2 metrics sent to Datadog

When creating a Datadog service integration, customize which metrics are sent to the Datadog endpoint using the Aiven CLI.

Supported metrics​

The following metric is supported for each replication flow in Apache Kafka® MirrorMaker 2:

  • kafka_mirrormaker_summary.replication_lag

The metric is tagged with replication-flow, enabling independent monitoring of each one of them.

note

The kafka_mirrormaker_summary.replication_lag metric is available as a custom metric in our Datadog integration. As a custom metric, it may be subject to separate billing by Datadog.

Variables​

Replace the following placeholders in the code samples:

VariableDescription
SERVICE_NAMEAiven for Apache Kafka® MirrorMaker 2 service name
INTEGRATION_IDID of the integration between Aiven for Apache Kafka® MirrorMaker 2 service and Datadog

To find the INTEGRATION_ID parameter, run:

avn service integration-list SERVICE_NAME

Customize metrics for Datadog​

Before customizing metrics, ensure a Datadog endpoint is configured and enabled in your Aiven for Apache Kafka service. For setup instructions, see Send metrics to Datadog. Format any listed parameters as a comma-separated list: ['value0', 'value1', 'value2', ...].

To customize the metrics sent to Datadog, use the service integration-update command with the following customized parameter:

  • mirrormaker_custom_metrics: Define the comma-separated list of custom metrics to include (currently, only kafka_mirrormaker_summary.replication_lag is supported).

For example, to send the kafka_mirrormaker_summary.replication_lag metric, execute the following command:

avn service integration-update                                                    \
    -c 'mirrormaker_custom_metrics=["kafka_mirrormaker_summary.replication_lag"]' \
    INTEGRATION_ID

After updating settings, view the collected metrics in your Datadog explorer.
