What are Load Averages?

by | Aug 23, 2018 | FAQ GRIDview-Group

What do load average values indicate?

System load/CPU Load – is a measurement of CPU over or under-utilization in a Linux system; the number of processes which are in waiting state. This is displayed in the Status Report as an average over a given period of time of 1, 5 and 15 minutes.

When load averages exceed the normal level of ~1.5 to 2.7 the Linux OS begins to allocate resources to the Open ADR system and conversely begins to shut down secondary (lower priority) systems to insure participation. 

When load average exceeds 4.0, the operational integrity of the unit may suffer. A reboot locally or restart services from GRIDview is recommended.

  • If the load average does not return to normal then contact the network administrator.
  • If the load average returns to normal but climbs over a period of days, contact tech support.
