A Practical Approach to NFS Response Time Monitoring
Gary Schaps, Peter Boehler Bishop · 1993
NFS and the automounter simplify both filesystem access and filesystem management in large, distributed networks. In demanding environments, however, they require a network management strategy which ensures a consistent and acceptable level of performance. 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.
