Revision as of 22:31, 21 June 2012

NFSometer is a performance measurement framework for running workloads and reporting results across NFS protocol versions, NFS options and Linux NFS client implementations.

The NFSometer project was started at NetApp by Weston Andros Adamson as a way to automate performance testing of the Linux NFS client. Since then it has grown to include many other features, notably the generation of reports. It is our hope that by releasing this project under the GPLv2 license, the Linux NFS community will benefit and hopefully contribute their own improvements to NFSometer.

Goals:

• Automate the time consuming process of running a variety of workloads looking for performance regressions between kernel versions, NFS protocol versions and NFS options.

• Generate reports that allows the user to understand the performance characteristics of workloads and easily compare performance characteristics in different configurations.

Example

The following command will run the Connectathon test suite once for each NFS protocol version (v3, v4, v4.1) and generate a report:

$ ./nfsometer.py zero:/export cthon

Requested: 1 workloads X 3 nfsopts X 1 runs = 3 test runs
Need to run 3 of 3 requested test runs
 cthon - needs 1 runs of vers=3 
 cthon - needs 1 runs of vers=4 
 cthon - needs 1 runs of vers=4,minorversion=1 

Trace 1/3: 1/1 with workload: cthon, nfsopts: vers=3
