If the host type is CCE, you can view disk partition metrics. The supported OSs are CentOS 7.6 and EulerOS 2.5.
Log in to the CCE node as the root user and run the docker info | grep 'Storage Driver' command to check the Docker storage driver type. If the command output shows driver type Device Mapper, the thin pool metrics can be viewed. Otherwise, the thin pool metrics cannot be viewed.
Memory usage = (Physical memory capacity – Available physical memory capacity)/Physical memory capacity; Virtual memory usage = ((Physical memory capacity + Total virtual memory capacity) – (Available physical memory capacity + Available virtual memory capacity))/(Physical memory capacity + Total virtual memory capacity) Currently, the virtual memory of a newly created VM is 0 MB by default. If no virtual memory is configured, the memory usage on the monitoring page is the same as the virtual memory usage.
For the total and used physical disk space, only the space of the local disk partitions' file systems is counted. The file systems (such as JuiceFS, NFS, and SMB) mounted to the host through the network are not taken into account.
Cluster metrics are aggregated by AOM based on host metrics, and do not include the metrics of master hosts.
