        Example: Using MapR Metrics to Diagnose a Faulty Network Interface Card (NIC)
        In this example, a node in your cluster has a NIC that is intermittently failing. This condition is leading to abnormally long task completion times due to that node being occasionally unreachable. In the Metrics interface, you can display a job's average and maximum task attempt durations for both map and reduce attempts. A high variance between the average and maximum attempt durations suggests that some task attempts are taking an unusually long time. You can sort the list of jobs by maximum map task attempt duration to find jobs with such an unusually high variance.

Results Filtering

By default, the MapR cluster software applies limits to the maximum number of records used for job and task histograms. You can configure these records from the MCS through System Settings > Metrics or by editing the db.conf file directly.

NOTE: These limits are applied before filtering.
