Some times you might want to split the time stamp of an event into smaller pieces, like month, day, hour etc.
For instance, you might want to see if you have more alerts during some specific hours of the day or if anyone is using RDP in the middle of the night.
To achieve this we use the function datetime_part which can split the time stamp to the following parts
This data could, of course, be used to further analysis and joined with other events.
//Sample query
AlertInfo
| extend alerthour = datetime_part("hour", Timestamp)
| summarize count() by alerthour, DetectionSource
| sort by alerthour asc
| render areachart For further reading about Kusto datetime_part, please visit
