Monitoring Switch Health

Diagnosing Switch Problems

page 24-24

OmniSwitch 6624/6648 Network Configuration Guide

April 2004

The following sections include a discussion of CLI commands that can be used to configure resource 
parameters and monitor or reset statistics for switch resources. These commands include:

•

health threshold

—Configures threshold limits for input traffic (RX), output/input traffic (TX/RX), 

memory usage

, 

CPU usage, and chassis temperature. See 

page 24-25

 for more information.

•

show health threshold

—Displays current health threshold settings. See 

page 24-26

 for details.

•

health interval

—Configures sampling interval between health statistics checks. See 

page 24-27

 for 

more information.

•

show health interval

—Displays current health sampling interval, measured in seconds. See 

page 

24-27

 for details.

•

show health

 —Displays health statistics for the switch, as percentages of total resource capacity. See 

page 24-28

 for more information.

•

health statistics reset

—Resets health statistics for the switch. See 

page 24-29

 for details.
