NFSometer

From Linux NFS

Revision as of 18:34, 20 June 2012

NFSometer is a framework for running and reporting performance characteristics of workloads across NFS protocol versions, options and Linux kernels.

Motivation

NFSometer was created to:

• 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 a report that allows the user to quickly understand the results and comparisons of workload runs, instead of having to manually dig through a lot of data.

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
