steve- Thanks for the work you've done. I'm sorry I thought you sent this to the ganglia-general mailing list and not just to me. Feel free to forward on your work to [email protected] and let others know about your work. thanks again -matt Wednesday, Steve Sutphen wrote forth saying... Hello, I have had the pleasure of installing the Ganglia package on a small cluster that we are building. One of the measures that I was interested in was missing - network traffic. I know that there are other rrd based tools (MRTG, and Cricket) that are aimed specifically at doing that task (I am using MRTG to monitor some of our network switches), but I liked the layout of Ganglia and thought that it would be a useful addition. I looked at building a script around gmetric, but it soon became obvious that this had a lot of overhead (starting several processes each time data was gathered), and saving the state of the counters between invocations was messy. I decided to hack up gmetric (I hope that my rather terse style coding style is not too offensive to the author(s)) and build a new self contained (it does not spawn other processes) and small (VSZ = 1564, rss=536) application to grab the network traffic stats, and multicast them. (I did not have time to put this in gmond where it really should be if one wanted to minimize the overhead.) In the spirit of Ganglia (and many other useful tools) I am making this publicly available with no strings attached. You can find it on our ftp server at ftp://www.cs.ualberta.ca/pub/Steve/gnetric.tgz, or there is a link from my web page: http://www.cs.ualberta.ca/~steve If you had suggestions of changes or what ever, feel free to send them my direction (although I don't have much time to work on this more, I might be convinced to). If anyone makes a major change, or incorporates it into gmond I trust that they will give it back to the community, although there is no obligation to do so. Thank you, steve.
