An audit directory holds a collection of audit files. Many audit directories are used in a typical installation. The three types of audit directories are as follows:
Primary audit directory – A directory where the audit files for a system are placed under normal conditions.
Secondary audit directory – A directory where the audit files for a system are placed if the primary directory is full or not available.
Directory of last resort – A local audit directory that is used if both the primary audit directory and all secondary audit directories are not available.
