Thank you Stuart.
May I ask why the maximum if 2.5mins?
By default Prometheus will look back for a maximum of 5 minutes to find
the "most recent" data point. Therefore if there was no data recorded in
the past 5 minutes a "no value" would be returned, and you'd have gaps
in your graphs. The recommended maximum of about 2-2.5 minutes is to
allow for a single scrape failure not to result in gaps as well as all
the various processing times to actually do the scrape.
