HBase Master

Collect HBase Master metric information

Config¶

1.HBase Master 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 HBase Master Start parameter adjustment¶

Adding startup parameters to HBase Master

{{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¶

By using jmx exporter, the metrics URL can be directly exposed, so it can be collected directly through the prom collector.

Go 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 instructions ：

• urls：jmx-exporter metric address, fill in the URL of the metric exposed by the corresponding component here
• source：Collector alias, it is recommended to make a distinction
• keep_exist_metric_name: Maintain metric name
• interval：Collection interval
• inputs.prom.tags: Add additional tags

3. Restart DataKit¶

Restart DataKit
