Maybe you are only initializing the counter when you increment it for the first time? See https://www.robustperception.io/why-predeclare-metrics as a starter. If you initialize the login counter to 0 upon starting up the app, it should work (provided Prometheus scrapes the app before the first login happens). Even if certain trolls (which none of us should ever feed) claim the opposite, Prometheus cannot know when a time series being scraped for the first time has started to exist. If the first value Prometheus sees for the login counter is a 1, it could in principle have been there for a very long time already. (I am contemplating using the new OpenMetrics creation timestamp to break out of this "existential issue", but even that is not as easy as it looks.) -- Björn Rabenstein [PGP-ID] 0x851C3DA17D748D03 [email] [email protected] -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
