Aggregate by time only

I would like to do a count of the amount of log entries over a certain time window, let's say one hour buckets. So log entries from monday 3-4pm should be counted with those from tuesday 3-4pm etc.

I have a timestamp field containing both the date and time. Would I need to split that field into a separate date and time field first and then perform the aggregation, or is there a clever way to do it without splitting the source data?

Hello @Maiky,

I'm not sure if I would have an ideal solution, but you can try to perform a cumulative sum per hour, something like: cumulative_sum(count(), shift='1h') . In this case, you would have the cumulative sum per hour for each day.
