    The service load service in Service Status in WHM: What resources is it based on that determine the load number? I'd like to better understand how the load number is calculated to get a better understanding of how stressed my server(s) are. Thanks in advance,

    I understand that it goes by an average server load, but what does that load consist of as far as resources? What makes up the server load?

    Also, that wiki article shows no results.

    Could someone from cPanel please reveal the formula that calculates how much CPU usage = cPanel Server Load? In other words, if the cPanel Server Load Status is showing as "2", how much CPU usage does this convert to? Thanks in advance.

    linux load average - Google Search

    Did you try to google it first? Take a look at this first page it does a pretty good job: https://www.andymillar.co.uk/blog/index.php/2006/12/24/geekery/linux-load-average-explained/

    What it boils down to is the linux load average is a mixture of multiple components. In general a load of 1 per cpu or core is going to keep the server running smoothly. That being said there are plenty of circumstances, such as when you don't have enough disk IO, where the load could be lower and it could be slow. Likewise you can have a significantly higher load but have the system still running ok.

    So basically it is not like windows where when you see 100% cpu usage or 1 on linux load average it is not 100%

    Thanks for the info! I was thinking it was a calculation that cPanel did, not a linux calculation and thus, didn't find anything relative. You answered my question thoroughly. I appreciate it :)

    Ahh great, I missed the point that you didn't associate the two together :)
