Enable deployment of performace monitoring¶
TripleO should have a possibility to automatically setup and install the performance monitoring agent (collectd) to service the overcloud.
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.
The collectd service will be deployed as a composable service on the overcloud stack when it is explicitly stated via environment file.
Other End User Impact¶
Metric collection and transport to the monitoring node can create I/O which might have performance impact on monitored nodes.

We should consider creating CI job for deploying overcloud with monitoring node to perform functional testing.
New template parameters will have to be documented.
