This paper reviews available tools for measuring NFS response time including rpcspy, nfswatch, nfsstat, and WireTap. We then describe a heuristic technique we have implemented on top of basic NFS response time statistics. It is used to create a management measure of network quality based upon NFS response time, and to proactively focus on NFS performance bottlenecks.
