Gopher Log Analyzer 3.4 Andy Wick awick@csugrad.cs.vt.edu

What is it: glog will allow you to analyze your gopher log files. Hopefully supplying you will useful reports/plots/histograms. It is very easy to use, and compile. It should compile with any standard ansi compiler, and now it should even work under VMS. (thanks Dennis R. Sherman)

To compile: (assuming gcc) gcc glog34.c -o glog

How to use: glog -h will display the options :). But as a short example.

To create a [H]ost report, a [D]ata report with detail of [H]osts and width of 132, a plot of [T]ypes with basename of "test", and finally a histogram of t[I]mes. The log file is called gopher.log. Don't forget, reports always go to stdout, unless the -o options is used.

% glog -rH -w 132 -rDH -f test -pT -gI < gopher.log | more

Tested on: Amiga DOS, SunOS 4.1.3 (purify 2.0.3), Ultrix 4.2A gcc 2.3.3 and higher was used on all platforms.

Features: * The command line is parsed as the reports/plots/histograms are generated, so that it is possible to change options for each separately. But options are NOT reset for each new one.

* Produces reports/plots/histograms on the [D]ata, [H]osts, day of the [W]eek, data [T]ypes, T[I]me, and [M]onth/date sorted (ie. sorted by date).

* Produces detailed reports on any thing you can produce a normal report for. Yes, you can even produce a host detail report of a hosts report. (But it doesn't do you much good :)

* Change the width of the reports.

* You can specify the filename for plots, it defaults to gopher. (The program appends a .dat, and and .run to the name)

* You can request as many plots as you want. (But remember to change the filename or you will overwrite the last plot)

* The program is now a lot easier to add new types of reports to, you only need to add 3 short routines, a variable, and edit 2 functions. (Well, maybe it is simple for me. :)

* Can select starting and ending month. (Sorry no wrap around)

* Average/Estimating can be done with the -aX option. Possible values for "X" are [E]verything (default), [Y]ear, [M]onth, [W]eek, [D]ay, and [H]our

Changes: 3.4 4/4/94 bug fixes and enhancements: Andy Wick - awick@csugrad.cs.vt.edu John-David Childs - jdc@selway.umt.edu Dennis R. Sherman - dennis_sherman@unc.edu

* improved coding efficiency in ProcessLine() * fixed bug when identifying FTP type to include ftp-vms: and ftp-nopasv: strings used by the NOPASV patch * allows DEFINING whether you want to output the text users searchs for * works under VMS * added histogram support * added averaging/estimating support * added input/output files options * fixed up this file and comments

3.3 7/20/93 bug fixes: John-David Childs - jdc@selway.umt.edu

* Fixed up main() routine so that: errors on the command line (or -h as the first parameter) cause glog to print the help information and abort. * Fixed PrintHelp() routine so help message is more understandable. * changed FILETYPE character from ' ' to 'I' (What about Image?)

3.2 7/19/93 Andy Wick - awick@csugrad.cs.vt.edu Slight bug in ProcessLine dealing with searches fixed.

3.1 7/17/93 Andy Wick - awick@csugrad.cs.vt.edu adds some features of the old glog that were removed by mistake. * Supports all known log entries now. (I was missing search, binary, and someothers) * Can now have a tIme report * The report presentation is a little better * Can specify a starting and ending month for the whole command with -s <num> and -e <num>. These are the only options that are used for the WHOLE command. The rest are from left to right.

TODO: * Fix up plots some more * Make some documentation * Improve error checking * Allow wrap around starting/stoping months.

If anyone has any ideas or suggestions please send them to me.
