MapR Topology Metrics

Every 60 seconds, the collectd service uses a MapR plugin to gather the following topology metrics on each node in the cluster. Use these metrics to understand disk utilization across a topology or rack. By default, these metrics include all racks and topologies associated with the cluster. However, you can use tags to specify which rack(s) or topologies(s) to include. Note: Racks and topologies can span multiple nodes and one rack can be associated with multiple topologies.

mapr.topology.disks_used_capacity The amount disk space used in gigabytes. This metric is available as of MEP 3.0.
  • rack_name: Display values for a specified rack.
  • topology_name: Display values for a specified topology. Provide the full topology path.
mapr.topology.utilization The aggregate percentage of CPU utilization. This metric is available as of MEP 3.0.
