Monitoring FreeNAS with InfluxDB and Grafana

At work I have done some monitoring projects which I’ve done many blog posts about. At home I have a small vSphere environment serving partially as a Lab but it also runs some services we use at home. Of course I do monitoring of this environment as well, and I use both InfluxDB and Grafana as we do at work.

One of my VMs runs Plex Media Server and recently I moved my media library to a separate box running FreeNAS. I’ve used FreeNAS as a part of my lab earlier as an ISCSI target and serving storage for VMs, but it’s now only serving my media files to the Plex VM.

The FreeNAS has it’s own performance monitoring available through the Web GUI, but of course I have wanted to incorporate it in my own monitoring solution. I’m not very familiar with the FreeBSD OS which FreeNAS runs on, and I wasn’t very keen on installing any agents on it. continue reading

vSphere Performance data – Monitoring VMware vSAN performance

In my blog series on building a solution for monitoring vSphere Performance we have scripts for pulling VM and Host performance. I did some changes to those recently, mainly by adding some more metrics for instance for VDI hosts.

This post will be about how we included our VSAN environments to the performance monitoring. This has gotten a great deal easier after the Get-VSANStat cmdlet came along in recent versions of PowerCLI.

We will build with the same components as before, a PowerCLI script pulling data and pushing it to an InfluxDB time-series database and finally visualizing it in some Grafana dashboards. continue reading
