Measureing System Performance

Hello all,

I've been sifting through the wiki, but I haven't found any tools bundled with WeBWorK for gathering and reporting time series data on system performance (such as CPU usage and network traffic). However, I did find the timing_log_check.pl script mentioned in the following link:


I would like finer data then this tool is generating. So, I am considering installing the RRDtool to get long-term statistics on my system (see http://en.wikipedia.org/wiki/RRDtool for more info), but I wanted to check first if anything else is available that I overlooked.

Thank you.

Hi Kurt,

I had not heard of that tool before, but it looks great. If you get it running and collect some data from it we'd really appreciate it if you could document it's use on the wiki - I think there is a lot of interest in collecting good performance data.

We have been using Munin [http://munin-monitoring.org] for quite a while. Here is what the default, out-of-the-box Munin install on Ubuntu shows for a dedicated Webwork box:

Before Munin, I tried RRDTool directly (http://www.math.dartmouth.edu/cgi-bin/ddr/webwork/webwork), and of course it's gives all the flexibility, and one can plot whatever they want, but it so much easier to just 'apt-get install munin-node' :)

Munin plugins are quite easy to write. Looks like the timing_log_check.pl can be a good start for at least one of such plugins. But what Webwork parameters (or their derivatives) would it be useful to keep track off over the time?

I have used Nagios to monitor my boxes, along with a modified script I found on here to dump out the number of users. I also have some R code that flips through the logs to see what kind of devices were accessing the site.

I am considering using Google Analytics to provide some more information on the network traffic.

In MAA on "Webwork" server, I am using “webmin” tool, which is basically a GUI interface for Linux administration and it has different add-on modules. One of the add-on is  “webmin system stats” for system performance / application monitoring.

Webminstats is a Webmin's module which display a graphical log of historic information. It's modular in design, as to be able to log everything from CPU usage to email box size.

URL for "Webmin" is http://www.webmin.com/

Tool "webmin system stats" can be downloaded  http://sourceforge.net/projects/webminstats/
