Use the following command to check the disk usage space. Ensure that the disk has at least 16 GB of free space to store critical files like logs and cores.

vcadmin@vcg1-example:~$ sudo df -kh --total | grep total | awk '{print $4}'
77G
vcadmin@vcg1-example:~$ 

The common places for disk usage to build up are /var/log, /velocloud/core, and /tmp.

Note: For DPDK-enabled gateways, each session creates a temporary file named as /velocloud/vctcpdump.XXXX with fixed size of 1MB. This file gets deleted when the session ends.
