Hi, yes, I have some opinions here. My proposal here is: - use collectd to collect low level metrics from your baremetal machines - use ceilometer to collect OpenStack related info, like project usage, etc. That is nothing you'd get by using node-exporter - hook them both together and send metrics over to something called Service Telemetry Framework. The configuration *is* included in tripleo. The website has documentation available https://infrawatch.github.io/documentation - graphite + grafana (plus collectd) is also a single node setup and won't provide you reliability. - collectd also provides the ability to send events, which can be acted on. That is not included if you use node-exporter, openstack-exporter etc. Prometheus monitoring creates events from metrics, but will be slow to detect failed components. Since prometheus is meant to be single server, there is no HA per se in prometheus. That makes handling prometheus on standalone machines a bit awkward, or you'd have a infrastructure taking care of that. In your tests with gnocchi, collectd and grafana, I bet you used swift as backend for gnocchi storage. That is not a good idea and may lead to bad performance.
