5.5.4. JobTracker CPU utilization

This host-level alert is triggered if CPU utilization of the JobTracker exceeds certain thresholds (200% warning, 250% critical). It uses the check_cpu.php plug-in which checks the JobTracker JMX Servlet for the SystemCPULoad property. This information is only available if you are running JDK 1.7.

 5.5.4.1. Potential causes
  • Unusually high CPU utilization: Can be caused by a very unusual job/query workload, but this is generally the sign of an issue in the daemon.

 5.5.4.2. Possible remedies
  • Use the top command to determine which processes are consuming excess CPU

  • Reset the offending processor.
