HBase Master

Collect HBase Master Metrics

Configuration¶

1. HBase Master Configuration¶

1.1 Download jmx-exporter¶

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

1.2 Download jmx Script¶

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

1.3 Adjust HBase Master Startup Parameters¶

Add the following to the HBase Master startup parameters:

{JAVA_GC_ARGS} -javaagent:/opt/jmx/jmx_exporter-1.0.1.jar=localhost:9406:/opt/jmx/hbase.yaml

1.4 Restart HBase¶

2. DataKit Collector Configuration¶

2.1 Install DataKit¶

2.2 Configure Collector¶

Since jmx-exporter can directly expose the metrics URL, you can collect data using the prom collector.

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

cp prom.conf.sample master.conf

Adjust the content of master.conf as follows:

  urls = ["http://localhost:9406/metrics"]
  source ="hbase-master"
  [inputs.prom.tags]
    component = "hbase-master" 
  interval = "10s"

Adjust other configurations as needed, parameter adjustment explanation:

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

3. Restart DataKit¶

Restart Datakit
