Why is CPU 30% on USG 210. Incoherencies in CPU statistiques

On the dashboard, the CPU is at 25%. But the graphic shows 40%. DEBUG SYSTEM PS reveals a sum of 3%. And CPU/MEMORY STATUS in DIAGNOSTICS reveals also about 3%. All APP WIRELESS features are disactivated. So I have 2 questions
1. why are there such incoherences in CPU stats ?
2. what is the real CPU ? and if it is 25% what service is concerned ?

Connect to Web Console or CLI Console (after logged-in) and type "show cpu average". This is showing you the CPU utilization, devided for each core. Additionally you will see the most CPU occupying services of the USG.0

Interesting but it doesn't really answer the question about incohérences between CPU stats.What period is used for calculating the average ? 24 hrs ? Since last reboot ?0

Hi @frerealexis,
When you enter the command on console, the value of the "CPU utilization" is the CPU (Core 0) usage at the moment you enter the command.
For example, when I enter the command "show cpu status" at 17:00, the CPU utilization at the moment 17:00 is 3%.
The average of CPU utilization of the previous 5 minutes (16:55-17:00) is 1%.
Router> show cpu status
CPU utilization: 3 %
CPU utilization for 1 min: 0 %
CPU utilization for 5 min: 1 %
To monitor all cores of CPU usage, go to MAINTENANCE > Diagnostics > CPU/Memory Status.
On the graph of CPU, the dot is generated by the average CPU usage of every 5 minutes. The dot is not generated by every second.
