Plotting data from logs

by Juliet Kemp

Very useful article on using gnuplot to plot log data information. I used it yesterday to look at the data on LDAP response rates that I've been collecting for a few weeks, and the suggested script (with appropriate minor changes) worked great. On the last line, points may be better than lines, depending on what you're graphing.

It transpires that the occasional blip in LDAP response rates here isn't particular time-dependent (although there's a couple of minor peaks at the two times when I know most people are around and doing stuff), so I need to consider the matter further.

I saw your comment regarding Gnuplot for log-analysis, and thought you might be interested to know that there is now a book on Gnuplot: "Gnuplot in Action". You can pre-order it directly from the publisher: Manning: Gnuplot in Action.

If you want to learn more about the book and the author, check out my book page at Principal Value - Gnuplot in Action.

Let me know if you are interested in a review copy.
