Analog Analog for Macintosh
Comments and questions: Jason@Summary.Net
I am a big fan of Stephen Turner´s log analysis program Analog. It is the most popular Web server log analysis tool in the world. It´s fast, flexible, easy to use, produces attractive output, and it´s FREE! For more information about Analog, or if you want a Unix, Windows, DOS, VMS, OS/2, VMS, Acorn, RiscOS, BeOS, or BS2000/OSD version, visit the Analog homepage.

Analog is a product of Stephen Turner. I maintain the Macintosh Classic version, and have contributed all of the Macintosh Classic specific code, as a service to the Macintosh user community. I originally ported Analog to the Macintosh because Analog was almost 250 times as fast as the best alternative at the time and it had a much more useful report as well. The full source code for the Macintosh version of Analog is available, including project files for Metrowerks CodeWarrior.

I also produce a commercial log analysis program, Summary, unrelated to Analog. It reports on many things that Analog doesn't, including visit counting, and is easier to configure and use, but then it isn't free.

Analog is currently available in four versions. Analog 6.0, available as a Carbon application for Mac OS 8.1 or newer, including Mac OS X. Analog 4.16 is a Classic Mac application for PPC Macs, Analog 3.2 is available for the 68K (very old Macs). Analog 2.1.1e is the last version with support for NetPresenz log format.

* DNSTran speed up DNS lookups and translates IP addresses into domain names.
* Analog Helper adds a native Macintosh user interface to Analog, $39 shareware.
* Report Magic adds graphs and some cool HTML formating to Analog. I ported Report Magic to the Macintosh, and like Analog it's free.
* Summary is my shareware alternative to Analog. It is easier to setup and has many more reports than Analog but it is not free.

February 13, 2001
Analog 4.16: Security fix for a buffer overflow bug. See for more information. Note that the Macintosh does not support the forms interface, so this is not a serious problem on the Macintosh. Some configuration settings might cause older versions of Analog to crash, but it is not a true security risk without the forms interface. Small correction to Brazilian Portuguese language file.
February 5, 2001
Analog 4.90b2: This is the first beta test for Analog version 5 on the Macintosh. As this is an early beta release, keep in mind that there may be bugs and crashes. If you need accurate and reliable reporting you should wait for a final version to be released. If you want a preview of the exciting new features coming in version 5 you should try this out. New features since version 4.1x include:
* Twelve new reports: Yearly Report, Quarterly Report, Five-Minute Summary, Quarter-Hour Summary, Hour of the Week Summary, Host Failure Report, Host Redirection Report, Virtual Host Failure Report, Virtual Host Redirection Report, User Redirection Report, Internal Search Word Report and Internal Search Query Report.
* Pie charts are now included at the top of most reports. *CHART commands to control them.
* New command GENSUMLINES to control which lines are listed in the General Summary.
* The "Distinct hosts" line now appears in the General Summary even if you aren't making a Host, Organization or Domain Report.
* New commands DESCRIPTIONS and DESCFILE to provide descriptions of each report.
* New commands REPORTSPAN and REPORTSPANTHRESHOLD to list the time period covered by each report.
* New commands ROBOTINCLUDE and ROBOTEXCLUDE for listing robots in the Operating System Report.
* New command INTSEARCHENGINE to allow the internal search reports. * New command DNSTIMEOUT (on some platforms) to reduce the time taken for failed DNS lookups.
* New LINKINCLUDE and LINKEXCLUDE commands. (See how to upgrade). * New columns E and e for time of first request; and S, s, Q, q, C and c for data in last 7 days; also corresponding SORTBY and FLOOR commands. * Substantial internal changes to allow these new columns without using extra memory if they are not wanted, and to substantially reduce code size (from what it would have been otherwise!).
* LaTeX output style.
* All files are now looked for in the "right" directories. This should improve usability substantially, especially from the form interface. (See how to upgrade).
* If you specify a CACHEFILE command but no LOGFILE command, analog won't read the default logfile. (See how to upgrade).
* US English now uses the 12-hour clock by default. (See how to upgrade).
* Computer readable output now reports the busiest time period for the time reports.
* Several commands have changed to better names, but the old names should still work.

Analog 1.92b1 Added support for new options in WebSTAR 2.0 log files. WebSTAR should be used in WebSTAR Format or Common Log Format. Extended Log Format is not supported. Fixed a bug with trailing periods on domain names.
October 8, 1996
Analog 1.92b Updated to the latest Unix version, providing support for English, US-English, French, German, Spanish, Italian, and Danish. Source available also.
October 6, 1996
Analog 1.91b4c Now reads NetPresenz log files, thanks to Nigel Perry (! Support is preliminary but appears to work.
October 5, 1996
Analog 1.91b4b source release includes the DNS lookup code and other minor bug fixes.
September 29, 1996
Analog 1.91b4b adds support for DNS lookups. Includes native support for MacTCP and OpenTransport. Also note that Analog is (and has been) compatible with WebCenter (version 1.0a7 or newer) logs in both WebSTAR compatible and common log file format modes.
July 22, 1996
Analog 1.91b4a solves a problem that caused a fatal error if OpenTransport was not present.
July 15, 1996
Analog 1.91b4, Cache file now includes page request information. Other minor bug fixes. Brought source code release up to current version.
July 9, 1996
Analog 1.91b3a, Fixes a problem with page hits in browser reports. Analog 1.91b3, Fixed the HOSTALIAS command, broken in the previous release.
July 8, 1996
Analog 1.91b2, Fixed problems with the HOSTEXCLUDE and CASE INSENSITIVE options. Now includes experimental DNS lookup code, set NUMLOOKUP ON in analog.cfg. This code is experimental, use with caution. DNS lookups can take hours for a large log file, and may freeze the machine for several minutes at a time. Standard release no longer includes source code.
July 2, 1996
Analog 1.91b, Updated to the latest Unix version. Many small changes including: new File Type Report, number of requests for pages (as opposed to raw requests) now calculated throughout, FILEALIAS a a and FILEALIAS a b; FILEALIAS b c now work, now quits automatically if no warnings have been issued, "Mozilla (compatible)" separated out in Browser Summary, major internal changes should improve speed, and many others.
Using Analog for Macintosh

I´ve added support for MacHTTP, Quid Pro Quo, WebSTAR Enhanced log files (WebSTAR version 1.2.1 or higher), and NetPresenz (Analog 2 only). I have not implemented a Macintosh style user interface or the Analog form cgi. Configuration is done in the Analog.cfg and manconf.cfg files. See the Analog ReadMe file for more information on the settings in these files.

Support for WebSTAR Enhanced log files and Quid Pro Quo in WebSTAR compatible mode requires that you include the following fields:
either HOSTNAME or both CS-HOST and CS-IP or both of C-IP and C-DNS, DATE, URL or CS-URI or CS-URI-STEM
It will also read BYTES_SENT, BYTES, TIME, RESULT, AGENT, REFERER, USER and CS_STATUS, if present, to provide additional information and reports. Order should not matter, and additional fields will be ignored. Analog parses the field order from additional information in the log file provided by WebSTAR 1.2.1 or higher. The WebSTAR DNS lookup option is not required, if it is off you may want to turn on DNS lookups in Analog. For Analog 2.1 set NUMLOOKUP to ON in Analog.cfg. For Analog 2.9 set DNS to WRITE in analog.cfg.

NetPresenz log files can be read in Analog version 2.x thanks to Nigel Perry ( with help from Peter Lewis. Processing NetPresenz log files changes the meaning or behavior of some Analogs reports. In Analog 2.1 when using NetPresenz the browser summary and detail reports do not contain information on browsers since NetPresenz does not record that information. Instead the browser report is used to report on the distribution of access between HTTP (web browsers), Gopher, and FTP. The browser detail report will further break FTP access down by user name. NetPresenz does not report the number of bytes transferred, so sorting by bytes transferred is suppressed and the bytes and %bytes columns will be blank if displayed. In Analog 2.9 none of this additional information is displayed and FTP and gopher requests are ignored.

If the report created by analog does not show anything except a small header and there are a large number of corrupt log file entries, Analog is probably failing to recognize that your log file is a WebSTAR log file. In order to read WebSTAR log files Analog looks for a line that starts with "!!LOG_FORMAT" followed by a list of fields separated by spaces. Versions of WebSTAR prior to 1.2.1 do not have this line, and so can only be read if you add it manually.

Users of AppleShare IP may need to manually set the log file format. Change the LOGFORMAT command in your analog.cfg file to two lines that read:
LOGFORMAT (%m/%d/%y\t %h:%n:%j\t%C\t%S\t%R\t%b)
LOGFORMAT (%m/%d/%y\t%h:%n:%j\t%C\t%S\t%R\t%b)

If you want Analog to always exit when processing is complete, set WARNINGS to OFF in manconf.cfg. This is handy if you have set up Analog to run periodically on your server machine. Be careful when using this option, since it is impossible to see most error messages in this mode. Normally Analog will exit if there are not any errors and will wait for you to quit if there are errors.

Analog now reads Zip (.zip), GZip (.gz), and BZip2 (.bz2) files automatically. People downloading logs from Unix machines will probably want to compress the log on the Unix machine, and Analog can then read that file directly. Mac users might also want to compress their log files to save disk space, this can be done with a program like MacGZip, available from InfoMac and other places.
