Apache HBase integration for Grafana Cloud

Apache HBase is an open-source non-relational distributed database modeled after Google’s Bigtable and written in Java. It is developed as part of Apache Software Foundation’s Apache Hadoop project and runs on top of HDFS or Alluxio, providing Bigtable-like capabilities for Hadoop.

This integration supports Apache HBase versions 3.0.0+

This integration includes 5 useful alerts and 3 pre-built dashboards to help monitor and visualize Apache HBase metrics and logs.

Before you begin

Apache HBase requires a JDK, Apache Zookeeper, and one of Hadoop or Alluxio. Ensure that each of these is installed and configured. Refer to this documentation for prerequisites and compatible versions for Apache HBase.

Apache HBase exposes a Prometheus metrics endpoint that is enabled by default.

Install Apache HBase integration for Grafana Cloud

In your Grafana Cloud stack, click Connections in the left-hand menu.
Find Apache HBase and click its tile to open the integration.
Review the prerequisites in the Configuration Details tab and set up Grafana Agent to send Apache HBase metrics and logs to your Grafana Cloud instance.
Click Install to add this integration’s pre-built dashboards and alerts to your Grafana Cloud instance, and you can start monitoring your Apache HBase setup.

Post-install configuration for the Apache HBase integration

After enabling the metrics generation, instruct the Grafana Agent to scrape your Apache HBase instance.

If you want to show logs and metrics signals correlated in your dashboards, as a single pane of glass, ensure the following:

job, hbase_cluster, and instance label values must match for metrics and logs scrape config in your agent configuration file.
job label must be set to integrations/apache-hbase (already configured in the snippets).
hbase_cluster label must be set to a value that identifies your Apache HBase cluster.
instance label must be set to a value that uniquely identifies your Apache HBase node. Please replace the default hostname value according to your environment - it must be set manually.

Configuration snippets for Grafana Agent

Below metrics.configs.scrape_configs, insert the following lines and change the URLs according to your environment:

    - job_name: integrations/apache-hbase
      metrics_path: /prometheus
      static_configs:
        - targets: ["localhost:<hostport>"]
          labels:
            hbase_cluster: '<your-cluster-name>'
            instance: '<your-instance-name>'

Below logs.configs.scrape_configs, insert the following lines according to your environment.

    - job_name: integrations/apache-hbase
      static_configs:
        - targets: [localhost]
          labels:
            job: integrations/apache-hbase
            hbase_cluster: '<your-cluster-name>'
            instance: '<your-instance-name>'
            __path__: <hbase_home>/logs/*.log
