I have installed the sysstat tool on a linux server. This server is used to host docker containers. Using sysstat I can see an overview of the CPU usage, memory etc.
The following command allows me to generate a SAR report for the current day.
sar -A -f /var/log/sa/sa19 > /tmp/sa19_$(uname -n).txt
This works fine to get an overview, but is it possible to know what processes are using the memory etc? I know this is possible in real time using the "top" command. Diving in even further, "ps aux" command allows me to see individual .net app docker containers. This is just out of the box stuff, so I'm inclined to believe that sysstat can gather such information.
I understand sysstat might not be the right tool for this, but is it possible to granulate the data and find the system load "culprit" if there was one?
