Ah I see, there is a problem about this. when httpServer is enabled, it doesn't registered `metrics` endpoint at the http router. so it fails with "Resource not found".
I am filing an issue for that: - https://github.com/apache/bookkeeper/issues/1538 for now, you can disable httpServer, so prometheus stats provider will start its own http server to expose metrics. hope that works for you. we will fix the issue and include it in the upcoming release. - Sijie On Mon, Jul 9, 2018 at 2:51 AM [email protected] < [email protected]> wrote: > > But i got "Resource not found"。 > > My config file is upload. > > ------------------------------ > [email protected] > > > *From:* Sijie Guo <[email protected]> > *Date:* 2018-07-09 15:30 > *To:* user <[email protected]> > *Subject:* Re: Re: Problem of Prometheus Stats Providers > Okay.
