HBase Region

Collect HBase Region metrics

Configuration¶

1. HBase Region Configuration¶

1.1 Download jmx-exporter¶

Download link: https://github.com/prometheus/jmx_exporter

1.2 Download jmx script¶

Download link: https://github.com/lrwh/jmx-exporter/blob/main/hbase.yaml

1.3 Adjust HBase Region startup parameters¶

Add the following to the HBase Region startup parameters:

{JAVA_GC_ARGS} -javaagent:/opt/jmx/jmx_exporter-1.0.1.jar=localhost:9407:/opt/jmx/hbase.yaml

1.4 Restart HBase¶

2. DataKit Collector Configuration¶

2.1 Install DataKit¶

2.2 Configure the collector¶

Since jmx-exporter directly exposes the metrics URL, it can be collected directly using the prom collector.

Navigate to the conf.d/prom directory under the DataKit installation directory, and copy prom.conf.sample to region.conf.

cp prom.conf.sample region.conf

Adjust the content of region.conf as follows:

  urls = ["http://localhost:9407/metrics"]
  source ="hbase-region"
  [inputs.prom.tags]
    component = "hbase-region" 
  interval = "10s"

Adjust other configurations as needed, parameter description:

• urls: The jmx-exporter metrics URL, fill in the metrics URL exposed by the corresponding component
• source: Collector alias, recommended for differentiation
• keep_exist_metric_name: Keep the metric name
• interval: Collection interval
• inputs.prom.tags: Add additional tags

3. Restart DataKit¶

Restart Datakit
