The vSAN team has just published a cool fling, the vSAN Performance Monitor. This performance monitor allows you to monitor multiple clusters at once, or as the team describes it:
The vSAN performance monitor is a monitoring and visualization tool based on vSAN Performance metrics. It will collect vSAN Performance and other metrics periodically from the clusters configured. The data collected is visualized in a more efficient and user-friendly way. The vSAN performance monitor comes with preconfigured dashboards which will help customers evaluate the performance of vSAN clusters, identify and diagnose problems, and understand current and future bottlenecks. The dashboards are heavily inspired by vSAN Observer.
It leverages Grafana for the frontend to visualize the metrics which are stored in an InfluxDB and collected by Telegraf. It is pretty simple to set up and it is made available for free via the Flings website. You can download an OVA and a User Manual to configure. Please note that it does require you to be on vSphere 6.0 or higher, but hopefully everyone is by now!
PS: Yes I know there was an issue with the upload of the OVA, I reported that with the dev team and it has been fixed since! Yes I tested it, and it does indeed import and boot correctly.
