webazolver [ option ... ] [ log-file ]

The Webalizer supports CLF (common log format) log files, as well as Combined log formats as defined by NCSA and others, and variations of these which it attempts to handle intelligently. In addition, the Webalizer also supports wu-ftpd xferlog formatted log files, allowing analysis of ftp servers, and squid proxy logs. Logs may also be compressed, via gzip. If a compressed log file is detected, it will be automatically uncompressed while it is read. Compressed logs must have the standard gzip extension of .gz.

webazolver is normally just a symbolic link to the webalizer. When run as webazolver, only DNS file creation/updates are performed, and the program will exit once complete. All normal options and configuration directives are available, however many will not be used. In addition, a DNS cache file must be specified. If the number of DNS children processes to use are not specified, the webazolver will default to 5.

This documentation applies to The Webalizer Version 2.01

o

A default configuration file is scanned for. A file named webalizer.conf is searched for in the current directory, and if found, and is owned by the invoking user, then its configuration data is parsed. If the file is not present in the current directory, the file /etc/webalizer.conf is searched for and, if found, is used instead.

o

Any command line arguments given to the program are parsed. This may include the specification of a configuration file, which is processed at the time it is encountered.

o

If a log file was specified, it is opened and made ready for processing. If no log file was given, STDIN is used for input. If the log filename '-' is specified, STDIN will be forced.

o

If an output directory was specified, the program does a to that directory in prepration for generating output. If no output directory was given, the current directory is used.

o

If a non-zero number of DNS Children processes were specified, they will be started, and the specified log file will be processed, creating or updating the specified DNS cache file.

o

If no hostname was given, the program attempts to get the hostname using a system call. If that fails, localhost is used.

o

A history file is searched for in the current directory (output directory) and read if found. This file keeps totals for previous months, which is used in the main index.html HTML document. Note: The file location can now be specified with the HistoryName configuration option.

o

If incremental processing was specified, a data file is searched for and loaded if found, containing the 'internal state' data of the program at the end of a previous run. Note: The file location can now be specified with the IncrementalName configuration option.

o

Main processing begins on the log file. If the log spans multiple months, a seperate HTML document is created for each month.

o

After main processing, the main index.html page is created, which has totals by month and links to each months HTML document.

o

A new history file is saved to disk, which includes totals generated by The Webalizer during the current run.

o

If incremental processing was specified, a data file is written that contains the 'internal state' data at the end of this run.

Some special precautions need to be taken when using the incremental run capability of The Webalizer. Configuration options should not be changed between runs, as that could cause corruption of the internal data stored. For example, changing the MangleAgents level will cause different representations of user agents to be stored, producing invalid results in the user agents section of the report. If you need to change configuration options, do it at the end of the month after normal processing of the previous month and before processing the current month. You may also want to delete the webalizer.current file as well.

The Webalizer also attempts to prevent data duplication by keeping track of the timestamp of the last record processed. This timestamp is then compared to current records being processed, and any records that were logged previous to that timestamp are ignored. This, in theory, should allow you to re-process logs that have already been processed, or process logs that contain a mix of processed/not yet processed records, and not produce duplication of statistics. The only time this may break is if you have duplicate timestamps in two seperate log files... any records in the second log file that do have the same timestamp as the last record in the previous log file processed, will be discarded as if they had already been processed. There are lots of ways to prevent this however, for example, stopping the web server before rotating logs will prevent this situation. This setup also necessitates that you always process logs in chronological order, otherwise data loss will occur as a result of the timestamp compare.
