The following example clears statistics counters for an end-to-end monitor: switch:admin> perfMonitorClear --class EE 1/2 5 End-to-End monitor number 5 counters are cleared switch:admin> perfMonitorClear --class EE 1/2 This will clear ALL EE monitors' counters on port 2, continue? (yes, y, no, n): [no] y The following example clears statistics counters for a filter-based monitor: switch:admin> perfMonitorClear --class FLT 1/2 4 Filter-based monitor number 4 counters are cleared switch:admin> perfMonitorClear --class FLT 1/2 This will clear ALL filter-based monitors' counters on port 2, continue? (yes, y, no, y): [no] y The following example clears statistics counters for an ISL monitor: switch:admin> perfMonitorClear --class ISL 1 This will clear ISL monitor on port 1, continue? (yes, y, no, n): [no] y Saving and restoring monitor configurations 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 end-to-end 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 end-to-end monitors for each port (from 0 to MAX_PORT) • The filter monitors for each port End-to-end 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, you will receive an error message indicating that the count has been exceeded and that some monitors have been discarded. To save the current end-to-end and filter monitor configuration settings into nonvolatile memory: 1. Connect to the switch and log in as admin. 2. Issue on of the following commands, depending on the action you want to perform: • To save the current end-to-end and filter monitor configuration settings into nonvolatile memory: 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. Fabric OS 6.1.x administrator guide 357
