Brocade Monitoring and Alerting Policy Suite Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 91)

• The “LSAN-imported device” metric is only monitored in switches that are a part of a Backbone
fabric.
• Scalability limits that are determined internally by a device cannot be monitored by MAPS.
Default rules for scalability limit monitoring
The following table lists the scalability monitoring default rules in each of the default policies, and shows
the actions and condition for each rule.

Examples of scalability limit rules
The following examples show the patterns for creating device counts, Fibre Channel router counts, and
zone configuration usage rules for MAPS.
Rule for device counts in a Layer 2 fabric
In the following example, when the total device count in all switches that are part of the Layer 2 fabric
rises above 90 percent of the total permissible count in the fabric, MAPS reports the threshold violation
using a RASLog message.
switch:admin> mapsrule --create L2_Dev_Count -group SWITCH -monitor L2_DEVCNT_PER -
timebase none -op ge -value 90 -action RASLOG -policy scalability_policy
