Monitoring a Ceph cluster with third-party options
In this section, we will see how to implement a third-party solution to monitor the Ceph cluster. There are several options that can be used to monitor a Ceph cluster graphically, which are as follows:
- Calamari: https://ceph.com/category/calamari/
- Kraken dash: https://github.com/krakendash/krakendash

This is the only free monitoring dashboard, and it is read-only, without any management ability. This is also safer, since an unauthorized user cannot make Ceph changes. The Ceph Calamari and Kraken dashboards are both equally challenging to install and configure.
The Ceph dashboard can be installed on any Ceph node or Proxmox+Ceph node in the cluster. As long as it can read the ceph.conf...
