<div dir="ltr"><div>Hi,<br></div><div><div><div><div><br></div><div>I created a blogpost on how to monitor your oVirt datacenter with Prometheus [1].<br><br>This way you get access to real time metrics and can use the powerful Prometheus query language, the Prometheus Alertmanager and visualization tools like Grafana.<br><br>Tasks like finding hosts which are underutilized, finding VMs
which are not behaving or even comparing resource usage profiles of whole
cluster over days become only a matter of writing the right Prometheus query. Further you can use the Prometheus Alertmanager for alerting.<br><br></div><div>An example which is also part of the post [1]: Visualizing the sum of the CPU usage of all VMs for ever host is as simple as<br><br></div><div> <code>sum(vm_cpu_user) by (host).</code></div><div><br></div><div>To close the gap between oVirt Engine and Prometheus I had to create two services vdsm-prometheus (github[2], docker hub[3]) and ovirt-prometheus-bridge (github[4], copr[5]). <br></div><div><br></div><div>An ansible role [6] to roll out vdsm-prometheus to all oVirt 3.5 or 3.6 hosts exists too.<br><br></div><div>So make sure to checkout the post [1] and let me know if you find this useful.<br></div><div><br></div><div>Best Regards,<br></div><div>Roman<br></div><div><br>[1] <a href="http://rmohr.github.io/virtualization/2016/04/12/monitor-your-ovirt-datacenter-with-prometheus" target="_blank">http://rmohr.github.io/virtualization/2016/04/12/monitor-your-ovirt-datacenter-with-prometheus</a><br></div><div>[2] <a href="https://github.com/rmohr/vdsm-prometheus" target="_blank">https://github.com/rmohr/vdsm-prometheus</a><br></div><div>[3] <a href="https://copr.fedorainfracloud.org/coprs/rfenkhuber/vdsm-prometheus/" target="_blank">https://copr.fedorainfracloud.org/coprs/rfenkhuber/vdsm-prometheus/</a><br>[4] <a href="https://github.com/rmohr/ovirt-prometheus-bridge" target="_blank">https://github.com/rmohr/ovirt-prometheus-bridge</a><br>[5] <a href="https://hub.docker.com/r/rmohr/ovirt-prometheus-bridge/" target="_blank">https://hub.docker.com/r/rmohr/ovirt-prometheus-bridge/</a><br>[6] <a href="https://galaxy.ansible.com/rmohr/vdsm-prometheus/" target="_blank">https://galaxy.ansible.com/rmohr/vdsm-prometheus/</a><br></div></div></div></div></div>
