The DeviceInfo table provides device information based on periodic reports or signals (heartbeats) from a device. Complete reports are sent every hour and every time a change happens to a previous heartbeat.

You can use the following sample query to get the latest state of a device:

// Get latest information on user/device
DeviceInfo
| where DeviceName == "example" and isnotempty(OSPlatform)
| summarize arg_max(Timestamp, *) by DeviceId
