The tools found in this section does not assume, that you are sitting on top of your box (which you are not, if you are a real system administrator). You don't even need a remote x-windows desktop. All you need is a browser.
Most of this section describes some of the things, I've been working on in my own time.
Problems, challenges, questions, that may be interesting, but not interesting enough to be pursued during working hours.
The programs are "askware". With the exception of the spider trap, you can't download the source code from this site. If you are interested, you'll have to ask me for a copy. Remember to include the word "please" somewhere in your letter ;-)
The dynamic log analyzer Dylan (written in Perl) does real-time analysis of web-server activity. Among other things it will tell you, how many people are visiting your site right now. Supported platforms are: Netscape/iPlanet web servers running on Solaris, it should work with Apache (and probably other web servers) as long as the underlying OS is some kind of UNIX or Linux. If your site is running on Windows 95, 98, NT, 2000 etc. it is most likely because you don't have the amount of traffic to justify a real server. In which case you don't need this tool.
What's Hot? (also a Perl program) uses an obscure Solaris command "prtdiag -v", available only on Sun hardware. It monitors the CPU temperature, and creates a graph, showing the results from the last 24 hours.
Werd, not "weird" though some may think it so. Another Perl program (am I repeating myself???)). While Dylan does a fair job when it comes to detecting robots or web-crawlers, Werd was written for that sole purpose. When walking the thin line between spamdexing (which is Bad), and promoting your web site (which is Good), Werd can - if configured properly - provide some indications as to how the search engines rank their results, and whether or not they are susceptible to subtle hints in META tags and such.
If you are working with the Sun/Solaris platform, there are lots of different scripts available from Sun's website. Take a look at scripts for monitoring Solaris servers for example.
