Indeed, in the Prometheus Web UI I can use ^F in the browser to look for N. Thank you for the hint. The problem is not to overwhelm the browser with data. > This is a use case where it would be nice to be able to build a range > vector directly out of a simple instant vector expression, i.e. "(foo == > N)[2d]".

I don't quite grok subqueries, but the resolution parameter seems to be optional. At least "(foo == N)[2d:]" seems to show the timestamps I was looking for. -- Victor Sudakov VAS4-RIPE http://vas.tomsk.ru/ 2:5005/49@fidonet -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
