I modified the passenger_memory_stats gist a bit to report also global memory stats. So we have an integrated view of the memory and how passenger relates to that. The modified version is also a gist: http://gist.github.com/562483 This is post is great! I modified the passenger_memory_stats gist a bit to report also global memory stats.

Concerning the ^M characters, that happens because it sounds like your RedHat distribution downloaded the text file with it's original DOS encoding, which handles newlines in text files differently than Unix encodings. You should <a href="http://chrisjean.com/2009/03/08/convert-dos-formatted-files-to-unix-format-in-ubuntu-and-centos/" rel="nofollow">check out the dos2unix</a> utility so that you don't have to manually get rid of all of the ^M characters. @Graham: Awesome, I’m glad it helped!

I did have a slight issue when importing directly onto RedHat... It seems that the original editor used to create 21391.txt and 20319.txt added the ^M character onto the end of the lines and when I executed the files, it gave an 'error 256' inside the munin-node.log and spit out a bad interpreter error to stdout. After a bit of googling, I found out that if you open the files in vim with a '-b' argument, it'll show you the ^M on the end of each line, which you can then delete as you wish. All in all, great plugin, thanks for this! Thanks for this, exactly what I wanted to do.
