4591 ndbinfo: The NDB Cluster Information Database os_time  uses the system  gettimeofday()  call. The values of the  os_ru_utime ,  os_ru_stime ,  os_ru_minflt ,  os_ru_majflt ,  os_ru_nvcsw , and os_ru_nivcsw  columns are obtained using the system  getrusage()  call, or the equivalent. Since this table contains counts taken at a given point in time, for best results it is necessary to query this table periodically and store the results in an intermediate table or tables. The MySQL Server’s Event Scheduler can be employed to automate such monitoring. For more information, see Section 25.4, “Using the Event Scheduler” . Notes 23.5.14.55 The ndbinfo transporters Table This table contains information about NDB transporters. The  transporters  table contains the following columns: • status • remote_node_id • node_id This data node’s unique node ID in the cluster The remote data node’s node ID OS involuntary context switches OS voluntary context switches OS page faults (hard page faults) OS page reclaims (soft page faults) OS system CPU time (µs) OS user CPU time (µs) OS time (ms) OS thread ID • os_now • os_ru_utime • os_ru_stime • os_ru_minflt • os_ru_majflt • os_ru_nivcsw • os_ru_nvcsw
