Thread-topic: Tools for tracing process switching in dom0
We are putting a heavy load on dom0 and some occasions we see cases
where processes appear to stall (based on timestamp information in their
log files).  I have not been able to determine what causes these
processes to starve for CPU cycles but I'm guessing some other higher
priority process/service may be coming in periodically and disrupting
our process.

I'm wondering if there are any Linux tracing/probing tools that work in
dom0 that would allow me to capture (with a timestamp) all process
context switches.
