Actieve sessies op SessionHost

Een grafiek met actieve sessies weergeven.

WVDAgentHealthStatus // Fires every ~30s
// Ensure only one data point is provided per host in the pool
| summarize PeakSessionsByHost=max(toint(ActiveSessions)) by SessionHostName, bin(TimeGenerated, 30s), _ResourceId
// Sum up the values for all of the hosts in each pool
| summarize SessionsByHostPool=sum(PeakSessionsByHost) by TimeGenerated, _ResourceId
// Reduce time resolution to desired GranularityInterval and report the peak session count for each pool in that time window
