# Apparmor Debugging
First look at the processes profile and skim the [query language][2].
## Tracking denials
Turn on complain mode
aa-complain <profile>
This does not track [denials][1]. So do a
apparmor_parser -pq /etc/apparmor.d/the.profile.to.check
and check for denails, turn them into "audit deny" for debugging.
## Other things to watch out for
* Process environments are usually cleared. So if a confined process spawns
a subprocess that relies on environments vars this might trigger problems
