System information

VNX™ System Operations108 of 114 Release 7.0
nas_stats
nas_stats allows the user to manage Statistics Groups. There are two types of
Statistics Groups: System and User-defined groups.
These groups are the same
groups that server_stats will display with –monitor, -list, and –info. nas_stats can be used to
modify existing System-defined Statistic Groups or it can be used to create new User-
defined Statistics groups.
For more information about the syntax and usage of the nas_stats command, refer to the
EMC VNX Command Line Interface Reference for File.
