Overview of Ranger and Observability integration
This guide provides the foundational knowledge and structured processes necessary to connect Apache Ranger with Cloudera's OpenTelemetry-native telemetry framework.
OpenTelemetry support for Ranger
Ranger uses a custom OpenTelemetry Collector distribution maintained by the Cloudera Observability team.
- Ranger Admin
- Ranger Admin supports OpenTelemetry (OTel) for exposing metrics to the Cloudera Observability infrastructure.
The integration uses a pull-based model, where the OTel Collector periodically scrapes the metrics endpoint exposed by Ranger Admin. The typical scrape interval is one minute. The integrated workflow works as follows:
.
The OTel Collector uses service discovery to discover and scrape the endpoint. Ranger Admin does not need to communicate directly with or be aware of the collector.
