Hi, The port 8765 is the "service discovery" (an internal server that runs in the mgr... you can change the port by changing the variable service_discovery_port of cephadm). Normally it is opened in the active mgr and the service is used by prometheus (server) to get the targets by using the http service discovery feature [1]. This feature has been there for a long time now and it's the default configuration used by Ceph monitoring stack. It should start automatically without any external intervention (or manual configuration). If it's not starting it means something weird is happening, probably watching mgr logs can shed some light. For that you have to go to the host where the active mgr is running and see the logs by running: systemctl | grep mgr journalctl -u <your_mgr_service> i.e: journalctl -u ceph-9414b9ce-6b63-11ef-bd07-525400d9fd68@xxxxxxxx-node-0.fiiqhv.service [1] https://prometheus.io/docs/prometheus/latest/http_sd/ On Thu, Sep 5, 2024 at 11:04 AM Eugen Block <eblock@xxxxxx> wrote: > Hi, > > regarding the scraping endpoints, I wonder if it would make sense to > handle it the same way as with the dashboard redirect: > > ceph config get mgr mgr/dashboard/standby_behaviour > redirect > > If you try to access the dashboard via one of the standby MGRs, you're > redirected to the active one. > > > Zitat von Matthew Vernon <mvernon@xxxxxxxxxxxxx>: > > > Hi, > > > > I tracked it down to 2 issues: > > > > * our ipv6-only deployment (a bug fixed in 18.2.4, though that has > > buggy .debs) > > > > * Discovery service is only run on the active mgr > > > > The latter point is surely a bug?
