The
UNIX command nfsstat invokes a performance monitoring
utility.
Nfsstat can provide
performance statistics for both the client and
server services. The results of the statistical analysis can provide assistance in tuning the system for increased performance.
Switches allow customizing the analysis to include or exclude items, such as just running the analysis on the server
services.
> nfsstat -s
Server rpc:
calls badcalls nullrecv badlen xdrcall
244 2 0 0 0
Server nfs:
calls badcalls null getattr setattr
197 2 12 2% 28 4% 0 0%
(... and a lot more data and statistics.)
After you have installed and debugged a network with UNIX, run the nfsstat command every so often to gauge the efficiency of the NFS.
