Re: [ceph-users] Ceph Monitoring
Hello Marius Vaitiekunas, Chris Jones, Thank you for your contributions. I was looking for this information. I'm starting to use Ceph, and my concern is about monitoring. Do you have any scripts for this monitoring? If you can help me. I will be very grateful to you.

Re: [ceph-users] Ceph - Health and Monitoring
Crai, Hi, I did not understand. I installed the plugins on the Ceph server, but what should I install on the Nagios server? The plugins installed on the Ceph server are working, but on the Nagios server they do not work, because the plugins need the installed Celp. What should I do? My plugins: check-ceph-dash.py check_ceph_df check_ceph_health check_ceph_mon check_ceph_osd check_ceph_rgw Site: https://github.com/valerytschopp/ceph-nagios-plugins Thank you.
