Switching User Names
The proc File System
The proc file system is a set of directories, beginning with /proc, that exist in
memory while ESX Server is running. The contents of these directories are not stored
on disk.
The /proc/vmware directory contains information specific to the running of the
ESX Server virtualization layer in virtual machines. You can use the cat command to
check status and use the echo command to write values to certain files in the proc
file system to change the configuration of ESX Server.
Note: Most of this information is also available through the VMware Management
Interface, and we strongly recommend that you obtain and set information through
this management interface. Do not add or change any options in this directory unless
you are instructed to by VMware support to solve an issue with ESX Server.
Caution: Do not use the proc interface to set any values other than those
mentioned in these sections:
• Managing CPU Resources from the Service Console on page 395
• Managing Memory Resources from the Service Console on page 411
• Manual NUMA Optimizations on page 420
• Managing Disk Bandwidth from the Management Interface on page 433
