About the Load Average Calculation Formula

Post by takashi.a » 2022/09/16 11:21:22

●Load Average Formula
load(t) = n+((load(t-1)-n)/e^(interval/(min*60)))

loat(t) : load average at time t
loat(t-1) : load average before time t (1 minute ago or 5 minutes ago or 15 minutes ago)

n: Number of running or uninterruptible threads
interval: interval between calculations (seconds). 5 seconds for RHEL(centos)
min: average time (minutes)
e: number of Napiers (2.7182...)

(1) Is the above recognition correct?
(2) Is it correct that the previous load average value is required for load average calculation?
