vSAN Health History, something I have been waiting for a long time

This is a small but also a very useful feature that comes with SAN 7.0 U2. In the former vSAN releases, when you troubleshooted vSAN issues (especially intermittent issues), vSAN Health showed the current status only. But if the issue occured from time to time you had to check the logs. Now you can enable the Health History in vCenter UI.

The historical health data is by default set to be kept up for 30 days back but this is sufficient in most of the cases.

After selecting the timeframe, you will see which checks failed and when did it happen.

I noticed that for backplane maintenance operations like data move, we get an Info icon, not a warning.

So now we can retrieve a historical snapshot of what happened with our vSAN cluster in the certain timeframe.
