Re: Grafana dashboards is missing data

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
