What Is Linux Load Average?

Linux load average is a metric that shows the number of tasks currently executed by the CPU and tasks waiting in the queue.

Unlike CPU usage, which measures system performance at a specific point in time, the load average shows performance over a particular period. 

A higher load average indicates higher resource usage.

Ideal Load average : 0.50 or 50% process

load average of 0 doesn’t mean the system is idle

dividing the number of running and waiting processes by the number of available CPU cores.

Generally, a load average of less than the number of CPU cores is normal, as it means there are enough resources for all processes to run smoothly.

A high load average with a low number of cores indicates an overwhelmed system. On the other hand, a low load average with a high number of cores means that the system has spare capacity and is able to manage more processes.

// Load average more than cpu cores means its overloaded , load average half of cpu core is normal.

Load average by CPU Cores

 

4 cores =4 is 100%

1 core = 1 % is process b

liunx load average 4 cores
load average in Linux
Load avg should be equal to core.
1,5,15 minutes by up time
07:13:53 up 8 days, 19 min,  1 user,  load average: 1.98, 2.15, 2.21
The numbers are read from left to right, and the output above means that:
load average over the last 1 minute is 1.98
load average over the last 5 minutes is 2.15
load average over the last 15 minutes is 2.21
