System monitoring using the sysMonitor command
8
Configuring the temperature threshold
1. Enter the sysMonitor command using the following parameters:
switch:admin > sysmonitor --config env -area temp -highth -value 99
-trigger above -action raslog
2. Apply the changes:
switch:admin > sysmonitor --apply env -area temp -action_level cust
-thresh_level cust
CPU and memory
When configuring memory, Limit specifies a usage limit as a percentage of available resources.
When used to configure CPU monitoring, specify a value in the 1-100 range. When CPU usage
exceeds the limit a Fabric Watch alert is triggered. The default CPU limit is 50% for the Brocade
48000 and 75% for all other platforms.
When used to configure memory monitoring the limit value must be greater than the low limit and
smaller than the high 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 in the range between the low limit and 90%. The default is 70% on the Brocade 48000
and 60% on all other platforms.
The following operands are valid only with --config mem. They provide two additional limits above
and below the middle usage limit.
• 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%. When
memory usage exceeds this limit, Fabric Watch generates a CRITICAL RASlog message. The
default is 90% for the Brocade 48000 and 80% for all other platforms.
• 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%.
Configuring the system memory usage monitoring threshold
1. Enter the sysMonitor command using the following parameters:
switch:admin > sysmonitor --config mem -poll 10 -retry 1 -limit 20
-action snmp, raslog -high_limit 80
2. Apply the changes:
switch:admin > sysmonitor --apply mem -action_level cust
