High disk utilization by vCMP for F5




Indeni will alert if the disk utilization of a vCMP is above a high threshold.

Remediation Steps

Run "show vcmp virtual-disk kil" to see the full data per vCMP. Purchase additional hardware or delete unused virtual disks. More information about virtual disk management can be found at https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/vcmp-viprion-configuration-11-4-1/7.html

How does this work?

This script logs into the device through SSH and extracts the host disk usage via TMSH.

Why is this important?

Running out of disk space on the vCMP host would mean that no new guests can be created. This alert would notify administrators of low disk space so they can prepare to clear some in case they need to deploy new guests.

Without Indeni how would you find this?

An administrator could track this manually by logging into the web interface, clicking on "vCMP" -> "Virtual Disk List". On this page the available disk space and the disk used by the guests is available. This information is also available by logging into the device through SSH, entering TMSH and executing the command "show vcmp global", followed by "show vcmp virtual-disk".
