Hadoop Yarn ResourceManager¶

Collect Yarn ResourceManager Metrics.

Installation and Deployment¶

Since ResourceManager is developed in Java, metrics can be collected using the jmx-exporter method.

1. ResourceManager 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/hadoop-yarn-resourcemanager.yml

1.3 ResourceManager Startup Parameter Adjustment¶

Add the following to the resourcemanager startup parameters:

{JAVA_GC_ARGS} -javaagent:/opt/jmx/jmx_exporter-1.0.1.jar=localhost:17109:/opt/jmx/jmx_resource_manager.yml

1.4 Restart ResourceManager¶

2. DataKit Collector Configuration¶

2.1 Install DataKit¶

2.2 Configure 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 resourcemanager.conf.

cp prom.conf.sample resourcemanager.conf

Adjust the contents of resourcemanager.conf as follows:

  urls = ["http://localhost:17109/metrics"]
  source ="yarn-resourcemanager"
  [inputs.prom.tags]
    component = "yarn-resourcemanager" 
  interval = "10s"

Other configurations should be adjusted as needed

, adjustment parameter descriptions:

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

3. Restart DataKit¶
