[rdo-users] TripleO Monitoring Tool/Method

Hi everybody, I am searching for a good and useful method to monitor my 40 nodes cloud. I have tried - Prometheus + Grafana (with https://github.com/openstack-exporter/openstack-exporter) but it cannot monitor nodes load and cpu usage etc. and - Gnocchi +Collectd + Grafana but it enforces unbelievable load on nodes and make the whole cloud completely unusable! I've tried to use Graphite + Grafana but I failed. Do you have any suggestions? P.S. Where can I find good documentation for TripleO over CentOS? Redhat's is somehow restricted to its own RHOSP. This website is down: http://tripleo.org/ Thanks, Khodayar
