This article documents several methods for monitoring disk utilization on CPMs.There are several methods for monitoring CPM disk utilization. This article shows examples of how to check disk usage either from Crossbeam CLI, from the Linux shell, or from GEM (Greenlight Element Manager). Another option is to monitor disk usage via SNMP.
Checking disk usage from the Crossbeam CLI
The command show disk-usage can be used to display disk utilization on the CPM:
This command can also be used to display utilization of local APM hard drives when changing the
source parameter. Another option is to use the
verbose parameter to change the output format.
Checking disk usage from the Linux shell
The standard UNIX
df command prints utilization of mounted filesystems. When executed with the
-h parameter, the sizes in the output are in human-readable format (e.g., 1K, 234M, or 2G).
[root@cb admin]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda7 12G 12G 0 100% /
/dev/sda1 101M 7.8M 88M 9% /boot
none 1.8G 0 1.8G 0% /dev/shm
/dev/drbd0 1.9G 129M 1.7G 8% /cbconfig
/dev/drbd1 36G 26G 8.7G 75% /tftpboot
/dev/drbd2 2.0G 37M 1.8G 2% /mgmt
Another way to check disk utilization from the Linux shell is the
/crossbeam/bin/cbs_disk_usage command. Output from this command is similar to the output of the
show disk-usage CLI command. Additionally, it prints the largest files on the filesystem.
Checking disk usage from GEM
From GEM, disk utilization can be observed in the CPMs view.
