I'm doing some performance testing of glusterfs and I'm trying to figure out the best way to analyze the data generated. iozone looks like a pretty good tool and I should be able to script an ensemble that varies the performance settings, but actually analyzing the generated data is too big a job to do manually. I spent quite a while yesterday loading the results into Open Office and generating charts for four test runs. They look good, but it is far too large a job to do manually, an ensemble will probably consist of hundreds of runs. My maintenance windows are this week on Wednesday & Thursday and I have no idea when I will be allowed to take the cluster down again. Ideas? Please? -- Matt
