PromQL filter based on current date

[Dipesh J]

Hi, 

Is there way to get metrics only for current date instead of using time like [24h] which would probably give metrics for day before too.

last 24 hours

my_metric{node="ABC"} [24h]

Something like below to give metrics for current date only.

my_metric{node="ABC"} [TODAYS_DATE]

Thanks

The only ways I know are to use the Prometheus API and set the evaluation time, or to use the @ timestamp PromQL modifier. But in either case you have to work out the timestamp of the end of the 24 hours of interest, and insert it yourself.
