Readme for analog3.0

Computer-readable output style

This section describes the computer-readable output style. You can select this style by means of the command 
OUTPUT COMPUTER
This style is designed to be easy to read into spreadsheets, or post-process with graphics creation tools, for example.

Each line in the output is separated into fields by means of a special string. You can specify this string by means of the COMPSEP command; for example 

COMPSEP :::
if for some reason you wanted three colons between each column. Make sure not to use anything that might occur in the output: for example, a single or double space would not be suitable.

Each line in the preformatted output begins with a letter indicating which report the line is part of. (The code letters for the reports are listed in the section on Configuring the Output.) After that, there follows a field indicating the remaining columns in the report (using the letters RrPpBbD as usual). Then there are the numerical data and then the name of the item. Times actually take up several fields: year, month, date, hour & minute, or as many of those as are necessary to identify the time.

The general summary is a bit different. After an initial x, there is a two-character code saying what the line contains. The possible codes are

HN
HOSTNAME
HU
HOSTURL
PS
Program start time
FR
Time of first request
LR
Time of last request
L7
Time last 7 days starts after
SR
Total successful requests
S7
Total successful requests in last 7 days
PR
Total successful requests for pages
P7
Total successful requests for pages in last 7 days
FL
Total failed requests
F7
Total failed requests in last 7 days
RR
Total redirected requests
R7
Total redirected requests in last 7 days
NC
Logfile lines without status code
C7
Lines without status code in last 7 days
NF
Number of distinct files requested
N7
Number of distinct files requested in last 7 days
NH
Number of distinct hosts served
H7
Number of distinct hosts served in last 7 days
CL
Number of corrupt lines in the logfile
UL
Number of unwanted lines in the logfile
BT
Total number of bytes transferred
B7
Total number of bytes transferred in last 7 days

If you do anything interesting with this output style, I should be delighted to hear about it. Anyone want to write a program to turn it into those pretty charts that executives seem to love?
