ICMP processing statistics

ICMP processing statistics appear in the output of the sm_tpmgr utility and will be similar to the following:

ICMP Accessor Interface:
                      avg_late_polling = 0.250944942235947
                          bytesPerPing = 64
       gets_causing_request_percentage = 0
            gets_from_cache_percentage = 100
                     icmpNumberOfPolls = 27109905
                  icmpNumberOfResponse = 1252990
                    icmpPollerTimeSkew = 0.250945
                         icmpStartTime = March 14, 2009 5:52:58 PM EST
            max_active_processing_time = 0
                          max_get_time = 0
              max_idle_processing_time = 0
                      max_late_polling = 0
                         max_lock_wait = 0
                          min_get_time = 1000
                    num_other_failures = 0
                           num_threads = 10
                          num_timeouts = 0
                        operation_size = 1
              periodic_gets_per_second = 0
             total_active_poll_actions = 0
                       total_get_nexts = 0
                 total_gets_from_cache = 30
    total_instrumentation_get_requests = 0
                  total_on_demand_gets = 0
                   total_periodic_gets = 0
                    total_poll_actions = 0
                      total_repos_gets = 30

Look for these statistics to evaluate performance:

• max_get_time, min_get_time: The maximum, and minimum duration (seconds) of a ping cycle.

• avg_late_polling: The amount of time (seconds) that the ICMP pinger is falling behind. If the value is negative, the pinger is ahead of schedule.
