HBase Region

Collect HBase Region Metrics Information

Configuration¶

1. HBase Region Configuration¶

1.1 Download jmx-exporter¶

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

1.2 Download jmx Script¶

Download address: 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/guance/jmx/jmx_exporter-1.0.1.jar=localhost:9407:/opt/guance/jmx/hbase.yaml

1.4 Restart HBase¶

2. DataKit Collector Configuration¶

2.1 Install DataKit¶

2.2 Configure Collector¶

The jmx-exporter can directly expose metrics url, so it can be collected through the prom collector.

Go to the conf.d/prom directory under the DataKit installation directory, 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"

Other configurations can be adjusted as needed, parameter adjustment description:

• urls: The jmx-exporter metrics address, fill in the metrics url exposed by the corresponding component here.
• source: Collector alias, it is recommended to differentiate.
• keep_exist_metric_name: Keep metric names.
• interval: Collection interval.
• inputs.prom.tags: Add extra tags.

3. Restart DataKit¶

Restart DataKit
