NAME

Apache::DBILogConfig - Logs access information in a DBI database

SYNOPSIS

# In httpd.conf
PerlLogHandler Apache::DBILogConfig
PerlSetVar DBILogConfig_data_source DBI:Informix:log_data
PerlSetVar DBILogConfig_username    informix
PerlSetVar DBILogConfig_password    informix
PerlSetVar DBILogConfig_table	     mysite_log
PerlSetVar DBILogConfig_log_format  "%b=bytes_sent %f=filename %h=remote_host %r=request %s=status"

DESCRIPTION

This module replicates the functionality of the standard Apache module, mod_log_config, but logs information in a DBI-compliant database instead of a file. (Some documentation has been borrowed from the mod_log_config documentation.)

LIST OF TOKENS

DBILogConfig_data_source

A DBI data source with a format of "DBI::driver:database"

DBILogConfig_username

Username passed to the database driver when connecting

DBILogConfig_password

Password passed to the database driver when connecting

DBILogConfig_table

Table in the database for logging

DBILogConfig_log_format

A string consisting of formats separated by white space that define the data to be logged (see FORMAT STRING below)

FORMAT STRING

A format string consists of a string with the following syntax:

%[conditions][{parameter}]format=field

format

Formats specify the type of data to be logged. The following formats are accepted:

a Remote IP-address
A Local IP-address (not yet supported)
B Bytes sent, excluding HTTP headers.
b Bytes sent, excluding HTTP headers. In CLF format i.e. a '-' rather than a 0 when no bytes are sent.
c Connection status when response is completed. 'X' = connection aborted before the response completed. '+' = connection may be kept alive after the response is sent. '-' = connection will be closed after the response is sent. (not yet supported)
e The contents of the environment variable specified by parameter
f Filename
h Remote host
H The request protocol
i The contents of the header (specified by parameter) in the request sent to the server.
l Remote logname (from identd, if supplied)
m The request method
n The contents of note (specified by parameter) from another module.
o The contents of the header (specified by parameter) in the reply.
p The canonical Port of the server serving the request
P The process ID of the child that serviced the request.
q The query string (prepended with a ? if a query string exists, otherwise an empty string)
r First line of request
s Status. For requests that got internally redirected, this is the status of the *original* request.
t Time, in common log format time format or the format specified by parameter, which should be in strftime(3) format.
T The time taken to serve the request, in seconds.
u Remote user (from auth; may be bogus if return status (%s) is 401)
U The URL path requested.
v The canonical ServerName of the server serving the request.
V The server name according to the UseCanonicalName setting (not yet supported).

field

A database column to log the data to

parameter

For formats that take a parameter

Example: %{DOCUMENT_ROOT}e

conditions

Conditions are a comma-separated list of status codes. If the status of the request being logged equals one of the status codes in the condition the data specified by the format will be logged. By placing a '!' in front of the conditions, data will be logged if the request status does not match any of the conditions.

Example: %!200,304,302s=status will log the status of all requests that did not return some sort of normal status

DEBUGGING

Debugging statements will be written to the error log if LOGLEVEL is set to 'warn' or higher

PREREQUISITES

  • mod_perl >= 1.11_01 with PerlLogHandler enabled

  • DBI

  • Date::Format

INSTALLATION

To install this module, move into the directory where this file is located and type the following:

perl Makefile.PL
make
make test
make install

This will install the module into the Perl library directory.

Once installed, you will need to modify your web server's configuration as above.
