Skyline/vSAN Health is the first place we go when we troubleshoot a vSAN cluster. But in case we have a problem that appears from time to time, it can happen that an updated vSAN Health report will not indicate any problems.
One of the simplest ways to check the historical vSAN Health data is to check them in your vCenter’s log file:
/var/log/vmware/vsan-health/vmware-vsan-health-summary-result.log
