I am trying to develop a multi-process system with RaspberryPi in which I want to monitor all major processes and how they are scheduled using Linux. That is, obtaining scheduler states, start time, release time etc. I have been messing with '/proc' folder in order to find such an information but I haven't able to find anything really useful so far.
For example, if you go into /proc/pid/task/pid you can see:
se.exec_start se.vruntime se.sum_exec_runtime se.statistics.wait_start se.statistics.sleep_start se.statistics.block_start se.statistics.sleep_max se.statistics.block_max se.statistics.iowait_sum se.statistics.wakeups
and so on. Now, this looks like I am up to something, but not clear enough. I want to just see how processes are scheduled in cores. i.e, Process1 released at 0.30, then Process2 started at 0.70 (system timer values) etc.
Is something like this possible by monitoring kernel folders such as '/proc'? If not, is there a way to determine this using another tracing tools or scheduler tools for Linux?
Any guidance is greately appreciated. Please tell me if there is something else I need to provide.
Thanks in advance.
