Overview

This metric can be used to identify where processes are consuming a large amount of processor time. The metric is produced when the partition is signalled using the bkstat -K<part>:SIGUSR2:Stacktrace command. The flag for the metric is cleared once the partition as caught the signal to avoid sending it multiple times.
