Hello Eugen, Well nothing about enabling port 9926. For example I see the following when deploying Grafanan: 2024-09-05 14:27:30,969 7fd2e6583740 INFO firewalld ready 2024-09-05 14:27:31,334 7fd2e6583740 DEBUG /bin/firewall-cmd: stdout success 2024-09-05 14:27:31,350 7fd2e6583740 INFO firewalld ready 2024-09-05 14:27:31,593 7fd2e6583740 DEBUG Non-zero exit code 1 from /bin/firewall-cmd --permanent --query-port 3000/tcp 2024-09-05 14:27:31,594 7fd2e6583740 DEBUG /bin/firewall-cmd: stdout no 2024-09-05 14:27:31,594 7fd2e6583740 INFO Enabling firewalld port 3000/tcp in current zone... 2024-09-05 14:27:31,832 7fd2e6583740 DEBUG /bin/firewall-cmd: stdout success 2024-09-05 14:27:32,212 7fd2e6583740 DEBUG /bin/firewall-cmd: stdout success But only the following when deploying ceph-exporter: 2024-09-05 12:17:48,897 7f3d7cc0e740 INFO firewalld ready 2024-09-05 12:17:49,269 7f3d7cc0e740 DEBUG /bin/firewall-cmd: stdout success When looking in the deploy configuration, Grafana shows 'ports': [3000], but ceph-exporter shows 'ports': [] Kind regards, Sake

Sorry, clicked "send" too soon. In a test cluster, cephadm.log shows that it would try to open a port if a firewall was enabled:
2024-09-09 10:48:59,686 7f3142b11740 DEBUG firewalld.service is not enabled 2024-09-09 10:48:59,686 7f3142b11740 DEBUG Not possible to enable service <ceph-exporter>. firewalld.service is not available

Do you see anything in the cephadm.log related to the firewall?
Zitat von Sake Ceph <ceph@paulusma.eu>:
After opening port 9926 manually, the Grafana dashboards show the data. So is this a bug?
Kind regards, Sake

That is working, but I noticed the firewall isn't opened for that port. Shouldn't cephadm manage this, like it does for all the other ports?
Kind regards, Sake

After the upgrade from 17.2.7 to 18.2.4 a lot of graphs are empty. For example the Osd latency under OSD device details or the Osd Overview has a lot of No data messages.
is the ceph-exporter listening on port 9926 (on every host)?
ss -tlpn sport 9926
Can you connect via browser?
curl localhost:9926/metrics
I deployed ceph-exporter on all hosts, am I missing something? Did even a redeploy of prometheus.
there is a bug, that this exporter does not listens for IPv6.
