Analog is a program to measure the usage on your web server.
It tells you which pages are most popular, which countries people are
visiting from, which sites they tried to follow broken links from,
and all sorts of other useful information.
How much does it cost?
Nothing. It's free.
How fast is it?
Very, very fast. Last time I checked, I was
uncompressing and processing
56 million logfile lines in 35 minutes on a 266MHz
chip: that's about 1GB of data every five minutes.
Of course, newer machines will be faster.
How big a logfile can it cope with?
It depends on your system. But I know of one site using it on logfiles
of over one billion lines (c. 100GB) [Google search].
Can it speak different languages?
Yes. You can have the output in any of 33 different
How configurable is it?
Very. The default output will be satisfactory for most people, but there
are hundreds of options producing 32 different
reports for those who want to do things differently.
Is it easy to install?
Yes. There are executables available for several platforms including
Windows (95/NT and later) and Mac, and it compiles straight out of the
box on most other platforms.
What platforms does it run on?
Almost any. It's written in standard C, so should compile on almost
any machine with a C compiler. It's known to work under Windows (all
versions), DOS, Mac, all Unix & Linux, OS/2, OpenVMS, Acorn RiscOS,
BeOS, Mac OS X, NeXTSTEP, and several mainframes. And probably more I
forgot to mention!
What web servers does it work with?
Any. The server just has to write its logfile in a form analog can read.
Analog can read all standard formats, and the user can specify
