Creating graphs from NMON

Here's how: (This has been tested this with Nmon version 9f, which you can download here):

  • Run nmon -f for a while. This will create nmon output files *.nmon in your current directory.
  • Make sure you've downloaded rrdtool.
  • Install rrdtool by unpacking it in /usr/local/bin.
  • Make sure directory /usr/local/bin is in your $PATH:
    # export PATH="$PATH:/usr/local/bin"
  • Create a directory for the output of the graphs:
    # mkdir output
  • Run the nmon2rrdv9 tool (found in the nmon download):
    # ./nmon2rrdv9 -f [nmon output file] -d ./output -x
  • In directory output an index.html and several gif files will be created. By accessing index.html in a web browser, you can view the graphs. For a sample, click here. Tip: use nweb as your web browser.
