HBase Master

Collect HBase Master Metrics Information

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 parameters to the HBase Master startup parameters:

{JAVA_GC_ARGS} -javaagent:/opt/guance/jmx/jmx_exporter-1.0.1.jar=localhost:9406:/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 a metrics URL, so you can use the Prometheus collector for collection.

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

Modify 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 metrics URL exposed by jmx-exporter, fill in the corresponding component's metrics URL here.
• source: Alias for the collector, it is recommended to distinguish them.
• keep_exist_metric_name: Keep metric names unchanged.
• interval: Collection interval.
• inputs.prom.tags: Add additional tags.

3. Restart DataKit¶

Restart DataKit

Metrics¶

Hadoop Measurement Set¶

HBase Master metrics are located under the Hadoop Measurement set. Below is an introduction to the relevant metrics for HBase Master.

Note: There is a duplicate entry for hadoop_hbase_fspreadtime_min which appears twice in the table. One entry should be corrected to hadoop_hbase_fsreadtime_min.
