There is no magic here, unfortunately.

Most implementations of monitoring will mean you have some agent running on the computes providing metrics to a central system. You could have node_exporter + Cadvisor exporting compute metrics + container metrics towards a central Prometheus server. You can then plug Grafana into Prometheus and have your centralized "single pane of glass" monitoring. It will require some work to create the dashboards and arrange all the visualization but I'm not aware of magical solutions that are free.

Yes, I’ve seen it. It’s totally simple and good, but I’d rather something which could be integrated/deployed with TripleO so that:

• We won’t be forced to deploy it on each node separately.
• We will be able to monitor all of cloud “as a cloud” and all of nodes together in a single page or program.

Node exporter is good but only for individual OSs.

Have you taken a look at the Prometheus Node Exporter? (https://github.com/prometheus/node_exporter) It will expose things like load average and disk usage for each node. These statistics can then be scraped into Prometheus and graphed with Grafana.

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
