Saving and restoring monitor configurations
To save the current end-to-end and filter monitor configuration settings into nonvolatile memory, use the
perfCfgSave command:
switch:admin> perfcfgsave
This will overwrite previously saved Performance Monitoring
settings in FLASH. Do you want to continue? (yes, y, no, n): [no] y
Please wait ...
Performance monitoring configuration saved in FLASH.
To restore a saved monitor configuration, use the perfCfgRestore command. For example, to restore
the original performance monitor configuration after making several changes:
switch:admin> perfcfgrestore
This will overwrite current Performance Monitoring settings in RAM. Do you
want to continue? (yes, y, no, n): [no] y
Please wait... Performance monitoring configuration restored from FLASH
ROM.
To clear the previously saved performance monitoring configuration settings from nonvolatile memory, use
the perfCfgClear command:
switch:admin> perfcfgclear
This will clear Performance Monitoring settings in FLASH. The RAM settings
won’t change. Do you want to continue? (yes, y, no, n): [no] y
Please wait... Committing configuration...done.
Performance Monitoring configuration cleared from FLASH.
To prevent the switch configuration flash from running out of memory, the number of monitors saved to flash
memory is limited as follows:
• The total number of EE monitors per port is limited to 16.
• The total number of filter monitors per port is limited to 16.
• The total number of monitors per switch is limited to 512.
When there are more than 512 monitors in the system, monitors are saved to flash memory in the following
order:
• The EE monitors for each port (from 0 to MAX_PORT)
• The filter monitors for each port
EE monitors get preference saving to flash memory when the total number of monitors in a switch exceeds
512. If the total number of monitors per port or switch exceeds the limit, then you will receive an error
message indicating the count has been exceeded and that some monitors have been discarded.
Collecting performance data
Data collected through Advanced Performance Monitoring is deleted when the switch is rebooted. Using
the Fabric Manager software application version 4.4.0 or later, you can store performance data
persistently. For details on this feature, see the Fabric Manager Administrator’s Guide.
