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

To complete the integration, you will:

  • Configure the JMX receiver for the Collector to ingest HBase metrics
  • Enable the integration by adding it to a pipeline

Prerequisites

HBase reporting

The HBase 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 HBase remote connection, see the official HBase documentation.

Configure the Collector receiver

In the Collector configuration file, add JMX 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 HBase instance
  • target_system: The metrics to collect. Valid values for this integration are jvm and hbase

receivers:
  jmx:
    jar_path: /opt/opentelemetry-jmx-metrics.jar
    endpoint: "hbase:9999"
    target_system: jvm,hbase
    

The OpenTelemetry repo’s readme provides additional details about JMX configuration.

Enable the Collector receiver

Once the HBase 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 HBase metric names. Search for metric

    See the OpenTelemtry repo for a complete list of emitted metrics.

  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.
