Passive NFS traces provide an easy and unobtrusive way to measure,
analyze, and gain an understanding of an NFS workload. Historically,
such traces have been used primarily by file system researchers in
an attempt to understand, categorize, and generalize file system
workloads. However, because such traces provide a wealth of detailed
information about how a specific system is actually used, they
should also be of interest to system administrators. We introduce
a new open-source toolkit for passively gathering and summarizing
NFS traces and show how to use this toolkit to perform analyses
that are difficult or impossible with existing tools.
