What is the definition for Jobs in 5 minutes / System load ? The definition of JOB means, the system load average.The term system load in UNIX computing term describes the amount of work that a computer system is doing.The load average is the system load over a period of time. An idle computer has a load number of 0. Each process that is using CPU, waiting for CPU or is in uninterruptable sleep (usually waiting for disk activity) adds 1 to the load number.
The load average is calculated as the exponentially damped moving average of the load number. The three values of load average refer to the past one, five, and fifteen minutes of system operation.
Application Manager gets the information by using the command called UPTIME or /bin/cat /proc/loadavg
This is monitored under System load in a Linux Server monitor in Applications Manager.
The system load averages for the past 1, 5, and 15 minutes in Linux server will be computed using above command. The server provides these values in decimal since it is average value.
For the convenience of setting up alerts,Applications Manager multiplies all the values uniformly by 100 and this change gives the option to setup a threshold to every value.
For example take this as Applications Manager reported values:
Jobs in Minute 53
Jobs in 5 Minutes 52
Jobs in 15 Minutes 45
The above values can be construed as:
Jobs in Minute 0.53
Jobs in 5 Minutes 0.52
Jobs in 15 Minutes 0.45
Please refer the below for more information on Load averages,
Average CPU Load (1 Minute)
The run queue or the load average is an average of the number of runnable processes waiting for the CPU during the last sixty seconds.The 1-min average is shown as Jobs in Minute in Applications Manager.
Average CPU Load (5 Minutes)
The run queue or the load average is an average of the number of runnable processes waiting for the CPU during the last five minutes.The 5-min average is shown as Jobs in 5 Minutes in Applications Manager.
Average CPU Load (15 Minutes)
The run queue or the load average is an average of the number of runnable processes waiting for the CPU during the last 15 minutes.The 15-min average is shown as Jobs in 15 Minutes in Applications Manager.
