Puppet Class: profile::hadoop::monitoring::history

Defined in:
modules/profile/manifests/hadoop/monitoring/history.pp

Overview

Class: profile::hadoop::monitoring::history

Sets up Prometheus based monitoring for the Hadoop MapReduce History server. This profile takes care of installing the Prometheus exporter and setting up its configuration file, but it does not instruct the target JVM to use it.

Parameters:

  • prometheus_nodes (Any) (defaults to: hiera('prometheus_nodes'))
  • hadoop_cluster_name (Any) (defaults to: hiera('profile::hadoop::common::hadoop_cluster_name'))
