You can do this by first using `label_replace` to create a new(!) label with the path prefix. Something like
count by(host) (label_replace(up, "host", "$1", "instance", > "([^:]+)(:[0-9]+)")) > link <https://prometheus.demo.do.prometheus.io/graph?g0.expr=label_replace(up%2C%20%22host%22%2C%20%22%241%22%2C%20%22instance%22%2C%20%22(%5B%5E%3A%5D%2B)(%3A%5B0-9%5D%2B)%22)&g0.tab=1&g0.stacked=0&g0.range_input=1h&g1.expr=count%20by(host)%20(label_replace(up%2C%20%22host%22%2C%20%22%241%22%2C%20%22instance%22%2C%20%22(%5B%5E%3A%5D%2B)(%3A%5B0-9%5D%2B)%22))&g1.tab=1&g1.stacked=0&g1.range_input=1h> However keep in mind that you are still incurring the storage cost of all these raw metrics. It *may* be worthwhile to fix this further up the chain in the app that exposes this data to begin with. /Matthias On Fri, Sep 29, 2023 at 1:16 PM [email protected] <[email protected]> wrote: > Hello, > > I have a question and could not get my head around it. may be if someone > can help. > > I have a recording rule the records rate of api requests for last 5 > minutes.
