Monitoring the Ceph cluster from the Calamari dashboard is fairly straightforward. Let's see how:
- The dashboard screen shows a lot of useful information.
- OSDs can be monitored using the OSD workbench option.
- Calamari gives some nice options to monitor the host resource usage in the form of graphs. The following graph represents the CPU summary for
ceph-node1:
- This graph represents the load average for
ceph-node1; do follow the legend for better understanding:
- Finally, the following is the memory usage graph from
ceph-node1. You can also view the memory usage in a timeline manner by adjusting the Time Axis option on the right-hand side:
