Disk Partition Metrics

  • 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.
