Hi,

I’m using Prometheus to monitor request durations via a histogram metric, 
e.g., http_request_duration_seconds_bucket. I would like to query:

   - The minimum time taken by a request
   - The maximum time taken by a request

…over a given time range (say, the last 1h or 24h).

I understand that histogram buckets give cumulative counts of requests 
below certain durations, but I’m not sure how to extract the actual min or 
max values of request durations during a time window.

Is this possible directly via PromQL? Or is there a recommended workaround 
(e.g., recording rules, external processing, or using histogram_quantile() in 
a specific way)?

Thanks in advance for any guidance!

Br,
Teja
