    Monitoring System Telemetry

    This topic describes using the Dremio Community Prometheus Exporter to collect Dremio system telemetry. The Dremio Community also provides an AWS CloudWatch Exporter and a Stackdriver Configurator:

    See the README.md in the CloudWatch exporter for instructions on generating a .jar file for AWS CloudWatch.


    Important: Dremio does not provide customer support for the Community Exporters and Configurator.

    To capture Dremio system telemetry, Dremio administrators perform the following tasks:

    1. Generate a dremio telemetry .jar file using Dremio OSS and a Dremio Exporter or Configurator.
    2. Deploy the .jar file and a telemetry configuration file to the Dremio deployment for which you want system telemetry.
    3. Restart Dremio.

    Generating a Dremio Telemetry .jar

    1. Open pom.xml in the Prometheus Exporter and update the <version> element to match the version in the pom.xml in Dremio OSS:

      Update <version> element in pom.xml
    2. Run the following command in the directory where you downloaded the exporter:

      mvn command
      mvn clean install

    The exporter creates a dremio-telemetry-prometheus-<dremio-oss-version>-shaded.jar file in the target directory.

    Deploy the .jar and Telemetry Configuration File

    1. Copy the .jar file from the target directory of the exporter to the /jars/3rdparty directory in the Dremio deployment for which you want to collect system telemetry.

    2. Create a dremio-telemetry.yaml configuration file in the /conf directory of your local Dremio deployment with the following scrape_configs section:

      A new version of the Dremio JDBC driver is made available periodically for use with Dremio Cloud. Release notes will be published when changes are made and a new driver version is released.

      See Configuration in the Prometheus documentation for more information about the Prometheus configuration file.

      Content for dremio.telemetry.yaml
       - job_name: dremio
         scrape_interval: 5s
           - targets:
               - localhost:12543
    3. Restart Dremio.

    To access the exported Dremio system telemetry, start a Prometheus server and point a web browser to localhost:9090\metrics. See Getting Started in the Prometheus documentation for details.
