Enable deployment of performace monitoring


TripleO should have a possibility to automatically setup and install the performance monitoring agent (collectd) to service the overcloud.

Problem Description

We need to easily enable operators to connect overcloud nodes to performance monitoring stack. The possible way to do so is to install collectd agent together with set of plugins, depending on a metrics we want to collect from overcloud nodes.

Summary of use cases:

1. collectd deployed on each overcloud node reporting configured metrics (via collectd plugins) to external collector.

Proposed Change


The collectd service will be deployed as a composable service on the overcloud stack when it is explicitly stated via environment file.

Security Impact


Other End User Impact


Performance Impact

Metric collection and transport to the monitoring node can create I/O which might have performance impact on monitored nodes.

Other Deployer Impact

Work Items

  • puppet-tripleo profile for collectd service

  • tripleo-heat-templates composable service for collectd deployment


  • Puppet module for collectd service: puppet-collectd [1]

  • CentOS Opstools SIG repo [2]


We should consider creating CI job for deploying overcloud with monitoring node to perform functional testing.

Documentation Impact

New template parameters will have to be documented.
