2. DataKit Collector Configuration¶

2.1 Install DataKit¶

2.2 Configure Collector¶

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

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

cp prom.conf.sample ranger-admin.conf

Modify the content of ranger_admin.conf as follows:

  urls = ["http://localhost:17143/metrics"]
  source ="ranger-admin"
  [inputs.prom.tags]
    component = "ranger-admin" 
  interval = "10s"

Adjust other configurations as needed, parameter adjustment instructions:

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

3. Restart DataKit¶
