AFS comes with three main monitoring tools:

The scout program, which monitors and gathers statistics on File Server performance.
The fstrace command suite, which traces Cache Manager operations in detail.
The afsmonitor program, which monitors and gathers statistics on both the File Server and the Cache Manager.

AFS also provides a tool for auditing AFS events on file server machines running AIX.
