Query specific time for last n days

[reklamo...@gmail.com]

Hi,

I have a gauge and I want to find out the values of it at 13:00 for last number of days.

I've found @ modifier ' http_requests_total @ 1643029200' and it would seem to provide the desired result but it only works for specific time of a single day. I am looking for something more dynamic. Is there some other way to do this?

Thanks

You can use a subquery to make a range vector:

http_requests_total[7d:24h] @ 1643029200

Or using the HTTP API, you can make a range query with your chosen start and end times and step.
