Fabric State Changes category parameters (Continued)TABLE 9
Monitored parameter Description
Percentage of devices in a
FCR-enabled backbone fabric
(LSAN_DEVCNT_PER)
Monitors the percentage of active devices in a Fibre Channel router-enabled
backbone fabric relative to the maximum number of devices permitted in the
metaSAN. This percentage includes devices imported from any attached edge
fabrics.
Used zone configuration size
(ZONE_CFGSZ_PER)
Monitors the “used zone configuration” size relative to the maximum zone
configuration size on the switch.
Number of FCRs in backbone
fabric (BB_FCR_CNT)
Monitors the number of Fibre Channel routers configured in a backbone fabric.
Switch Resource
Switch resource monitoring enables you to monitor your system’s temperature, flash usage, memory
usage, and CPU usage.
You can use Switch Resource monitors to perform the following tasks:
• Configure thresholds for MAPS event monitoring and reporting for the environment and resource
classes. Environment thresholds enable temperature monitoring, and resource thresholds enable
monitoring of flash memory.
• Configure memory or CPU usage parameters on the switch or display memory or CPU usage.
Configuration options include setting usage thresholds which, if exceeded, trigger a set of specified
MAPS alerts. You can set up the system monitor to poll at certain intervals and specify the number
of retries required before MAPS takes action.
The following table lists the monitored parameters in this category.
Switch Resource category parametersTABLE 10
Monitored parameter Description
Temperature (TEMP) The ambient temperature inside the switch in degrees Celsius. Temperature
sensors monitor the switch in case the temperature rises to levels at which
damage to the switch might occur.
Flash (FLASH_USAGE) The available compact flash space, calculated by comparing the percentage of
flash space consumed with the configured high threshold value.
CPU usage (CPU) The percentage of CPU available, calculated by comparing the percentage of
CPU consumed with the configured threshold value.
Memory (MEMORY_USAGE) The available memory, calculated by comparing the percentage of memory
consumed with the configured threshold value.
Management Port
(ETH_MGMT_PORT_STATE)
The status of the management port (Eth0 or Bond0).
