|
Review AppArmor generated messages in a colorful way. Supports logs from
|
|
auditd, systemd, syslog as well as dbus session events.
|
|
|
|
It can be given an optional profile name to filter the output with.
|
|
|
|
Default logs are read from '/var/log/audit/audit.log'. Other files in
|
|
'/var/log/audit/' can easily be checked: 'aa-log -f 1' parses 'audit.log.1'
|
|
|
|
Options:
|
|
-h, --help Show this help message and exit.
|
|
-f, --file FILE Set a logfile or a suffix to the default log file.
|
|
-s, --systemd Parse systemd logs from journalctl.
|
|
-r, --rules Convert the log into AppArmor rules.
|
|
-R, --raw Print the raw log without any formatting.
