Hey everyone, Today we will see the best ways How To Check the Load Average In Linux. We will also see a small tutorial and a detailed guide for checking the load average in Linux.
Load average is the average number of tasks and processes currently running or waiting to consume the CPU resources over the last 1, 5, or 15 minutes. It represents the system utilization where 1.0 means full utilization of a single CPU core. You can check it using top, uptime, or by manually reading from /proc/loadavg.
Top 4 Methods For Checking Load Average In Linux

/proc/loadavg is a virtual file in our Linux system that provides information about the load average in our Linux system or server. It contains the 5 values let’s see what information this value provides.
cat /proc/loadavg
Value in Proc/loadavg | Definition and indication of value |
---|---|
1st value ( ex : 0.03 ) | provides the average number of processes running from last 1 minute |
2nd value ( ex: 0.07 ) | provides the average number of processes running from last 5 minute |
3rd value ( ex: 0.10 ) | provides the average number of processes running from last 15 minute |
4th value ( ex: 5/369 ) | 1st value ( ex: 0.03 ) |
5th value ( ex: 21298 ) | Provides the ID of the most recently created process |
