Thanks are due to the author of getstats, Kevin Hughes. In the days before analog there were only three serious logfile analysis programs, and only one of them, getstats, had attractive output. I wrote analog when getstats stopped being able to cope with the size of our logfile, but my output still looks somewhat similar to his.
Thanks are also due to all those who helped in the early stages of writing this program, and gave me the encouragement to continue with analog and to release it publicly. Those who made helpful suggestions during the first few weeks of the program are numerous, but I must mention particularly Dan Anderson, Martyn Johnson, Joe Ramey, Chris Ritson, Quentin Stafford-Fraser and Dave Stanworth. Above all Gareth McCaughan gave me lots of programming advice. The program would have run much more slowly without him.
My employer, the University of Cambridge Statistical Laboratory, kindly lets me distribute analog from their web server, and the Christmas Island domain provides the address analog.cx. Many other people have provided mirror sites for analog, starting with Dave Stanworth (again!). The full list of mirror sites is listed elsewhere; thanks to all of them. Many thanks also to ISite for providing the mailing lists, and to The Mail Archive for archiving the analog-help list.
Mark Roedel first suggested porting analog to different platforms, and made the original DOS port. Shortly afterwards, Jason Linhart made the Mac port, and has continued to contribute lots of extra code for that platform and for the program in general. The Mac version also includes code contributed by Stephan Somogyi and Nigel Perry. Later ports were made by Dave Jones, Martin Zinser & Rick Dyson (OpenVMS), Magnus Hagander (Win32), Ivan Martinez (OS/2), Nick Smith (Acorn RiscOS), Scott Tadman (BeOS), Thomas Engel (NeXTSTEP), Martin Kraemer & Holger Schranz (BS2000/OSD, including EBCDIC support), and Hideyuki Yahagi (AS/400). Thank you also to the people who make precompiled versions available for various platforms.
The regular expression parsing is taken from Philip Hazel's excellent PCRE library. The graphics use Thomas Boutell's gd library, the libpng library, and the zlib library by Jean-loup Gailly & Mark Adler. The zlib library is also used for logfile decompression on the Mac. Each of these libraries is subject to its own copyright and licensing conditions: PCRE licence, gd licence, libpng licence, zlib licence. The BS2000/OSD port includes code developed by the Apache Group for use in the Apache HTTP server project. If NEED_MEMMOVE is defined at compile time, then this product includes software developed by the University of California, Berkeley and its contributors.
The form interface is based on an idea by James Dean Palmer. Thanks to all the other people who have contributed bits of code too: I apologise for not having room to name all of them. And thanks to those who have written helper applications, for making analog more usable.
