So my last post was about administration on Linux. After running Oracle on Windows for way too many years we migrated our Oracle systems to 64-bit Linux over the past year.
Now that we're on Linux I needed a lightweight way to capture and graph some performance data. The performance data was a mix of OS utilities and 3rd party utilities, but all the utilities output text, so I knew I could screen scrape the output, massage it a little, and save the data to a file. After I had the data in a file I knew I could run it through GnuPlot to graph it.
