[ceph-users] Prometheus endpoint hanging with 13.2.7 release?

Hello, Anybody seeing the Prometheus endpoint hanging with the new 13.2.7 release? With 13.2.6 the endpoint would respond with a payload of 15MB in less than 10 seconds. Now, if you restart ceph-mgr, the Prometheus endpoint responds quickly for the first run, then successive runs get slower and slower, until it takes several minutes. I have no customization for the mgr module. Except for the Prometheus module, the "status" module and "Zabbix" module are working fine. This is on Ubuntu 16 LTS: ii ceph-mgr 13.2.7-1xenial amd64 manager for the ceph distributed storage system I'd love to know if there's a way to diagnose this issue - I tried upping the debug ms level but that doesn't seem to yield useful information. I don't know if this useful, but "prometheus self-test" is fine too. $ sudo ceph tell mgr.0 prometheus self-test Self-test OK pchoi@pchoi-desktop:~$ ceph mgr module ls { "enabled_modules": [ "prometheus", "status", "zabbix" ], "disabled_modules": [ { "name": "balancer", "can_run": true, "error_string": "" }, { "name": "crash", "can_run": true, "error_string": "" }, { "name": "dashboard", "can_run": true, "error_string": "" }, { "name": "hello", "can_run": true, "error_string": "" }, { "name": "influx", "can_run": false, "error_string": "influxdb python module not found" }, { "name": "iostat", "can_run": true, "error_string": "" }, { "name": "localpool", "can_run": true, "error_string": "" }, { "name": "restful", "can_run": true, "error_string": "" }, { "name": "selftest", "can_run": true, "error_string": "" }, { "name": "smart", "can_run": true, "error_string": "" }, { "name": "telegraf", "can_run": true, "error_string": "" }, { "name": "telemetry", "can_run": true, "error_string": "" } ] } pchoi@pchoi-desktop:~$ ceph mgr services { "prometheus": "http://woodenbox2:9283/" }
