Hbase Master

Agent Check Agent Check

Supported OS: Linux Mac OS Windows

Overview

Get metrics from Hbase_master service in real time to:

  • Visualize and monitor Hbase_master states.
  • Be notified about Hbase_master failovers and events.

Installation

If you are using Agent v6.8+ follow the instructions below to install the Hbase_master check on your host. See our dedicated Agent guide for installing community integrations to install checks with the Agent prior v6.8 or the Docker Agent:

  1. Install the developer toolkit.
  2. Clone the integrations-extras repository:

    git clone https://github.com/DataDog/integrations-extras.git.
    
  3. Update your ddev config with the integrations-extras/ path:

    ddev config set extras ./integrations-extras
    
  4. To build the hbase_master package, run:

    ddev -e release build hbase_master
    
  5. Download and launch the Datadog Agent.

  6. Run the following command to install the integrations wheel with the Agent:

    datadog-agent integration install -w <PATH_OF_HBASE_MASTER_ARTIFACT_>/<HBASE_MASTER_ARTIFACT_NAME>.whl
    
  7. Configure your integration like any other packaged integration.

Configuration

  1. Edit the hbase_master.d/conf.yaml file in the conf.d/ folder at the root of your Agent’s configuration directory to start collecting your Hbase_master metrics. See the sample hbase_master.d/conf.yaml for all available configuration options.

  2. Restart the Agent

Validation

Run the Agent’s status subcommand and look for hbase_master under the Checks section.
