Resource class settings

The flash area of the Resource class monitors the percentage of compact flash memory used on

the system.

Displaying the system flash parameters

Enter the sysMonitor command using the following parameters:

switch:admin> sysmonitor --show resource -area flash

CPU and memory

When configuring CPU monitoring, specify a value in the range from 1 through 100. When the CPU

usage exceeds the limit, a Fabric Watch alert is triggered. The default CPU limit is 75 percent.

When configuring memory, the limit specifies a usage limit as a percentage of available resources.

When used to configure memory monitoring, the limit value must be greater than the low limit and

smaller than the high limit.

The following operands are valid only with the --config mem command. Three thresholds are

supported for memory monitoring:

• high_limit— Specifies an upper usage limit for memory as percentage of available memory.

This value must be greater than the value set by the -limit parameter. The maximum is 90

percent. When memory usage exceeds this limit, Fabric Watch generates a CRITICAL RASlog

message. The default is 80 percent.

• limit—Specifies the default CPU limit. When the limit is exceeded, Fabric Watch sends out a

RASlog WARNING message. When usage returns below the limit, Fabric Watch sends a RASlog

INFO message. Valid values are range from 0 through 80 percent and the default value is

different for different systems.

• low_limit—Specifies a lower usage limit for memory as percentage of available memory. This

value must be smaller than the value set by the -limit parameter. When memory usage exceeds

or falls below this limit, Fabric Watch generates an INFO RASlog message. The default for all

platforms is 50 percent.
