CPU and memory
When configuring CPU monitoring, specify a value in the 1-100 range. 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 between 0 to 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.
Examples of the CPU and memory commands
The following sections provides specific examples for CPU and memory.
