Hey, I need help understanding some metrics.
Zabbix version: 5.0
Agent: zabbix-agent2
Template: Official Docker template
Problem 1
If I run docker system df
I suppose the total size of the images in disk is 19.6GB
but zabbix Docker: Images size item is returning 35.49GB
Problem 2
The template has no item to get the cpu/mem percentage usage of each container
but I don't know if its possible to calculate with some of these
CPU kernelmode usage per second
CPU total usage per second
CPU usermode usage per second
How do I know what impact is taking on the host with these metrics ?
Another issue I see is some of the containers with the docker stats command report values of over 100% I don't think docker takes the number of cores into consideration.
Thank you
