[Koha-devel] Unable to access plack middleware ( Plack::Middleware::Prometheus::RequestTimes )

Hey yinz, I’m trying to add some Prometheus metrics to Koha. This looks like it has what we want: https://metacpan.org/pod/Plack::Middleware::Prometheus::RequestTimes Really, I’d like response times per script, but I’m not that picky just yet. I tried this on /etc/koha/plack.psgi but I just get a 404 for 127.0.0.1:8081/metrics. No errors in the logs. Any thoughts? Here's my POC commit: https://github.com/bywatersolutions/bywater-koha-devel/commit/472436f7a05a8a... --- http://www.kylehall.info ByWater Solutions ( http://bywatersolutions.com ) Meadville Public Library ( http://www.meadvillelibrary.org ) Crawford County Federated Library System ( http://www.ccfls.org )
