Hi ceph-users, I'm not sure if this mail got send correctly, my colleague seems to not have received it. Either way. We've managed to replicate this issue from a local http_check test. The ceph-mgr seems to go down with every first visit, and works perfectly fine right after a couple re-visits. Has anyone else seen this issue before? Thanks in advance, - Demian From: Demian Romeijn <dromeijn(a)tuxis.nl> To: <ceph-users(a)ceph.io> Sent: 12/22/2023 2:14 PM Subject: ceph-dashboard odd behavior when visiting through haproxy I'm currently trying to setup a ceph-dashboard using the official documentation on how to do so. I've managed to log-in by just visiting the URL & port, and by visting it through haproxy. However using haproxy to visit the site results in odd behavior. At my first login, nothing loads on the page and eventually at ~5s it times me out, sending me back to the log-in screen. After logging back on to the dashboard, everything loads and functions as expected. I can refresh my browser as many times as I want and it still keeps on working. After some time, usually ~30 minutes or so of inactivity, the problem arises again. Haproxy tells us the server is down for about ~10 seconds, running a simple HTTP check results in the following aswell: CRITICAL - Socket timeout after 10 seconds. In the ceph-mgr logs there isn't any special error other than: [dashboard ERROR frontend.error] (https://*redacted*/#/login): Http failure response for https://*redacted*/ui-api/orchestrator/get_name: 401 OK None It seems as such the ceph dashboard is "overloaded", changing haproxy config (following the official ceph documentation on how to set it up) to do health-checks less often results in the problem happening less often. Anything I might've overlooked that could sort out the issue?
