webalizer(1) The Webalizer webalizer(1)
NAME webalizer - A web server log file analysis tool. SYNOPSIS webalizer [ option ... ] [ log-file ] webazolver [ option ... ] [ log-file ] DESCRIPTION The Webalizer is a web server log file analysis program which produces usage statistics in HTML format for viewing with a browser. The results are presented in both columnar and graphical format, which facilitates interpretation. Yearly, monthly, daily and hourly usage statistics are presented, along with the ability to display usage by site, URL, referrer, user agent (browser), username, search strings, entry/exit pages, and country (some information may not be available if not present in the log file being processed). 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 intel‐ ligently. In addition, the Webalizer supports xferlog formatted (FTP) log files, squid proxy logs and W3C extended format logs. Logs may also be compressed, via gzip (.gz) or, if enabled at compile time, bzip2 (.bz2). 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 or bzip2 extension of .bz2. 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 2.23 RUNNING THE WEBALIZER The Webalizer was designed to be run from a Unix command line prompt or as a crond(8) job. Once executed, the general flow of the program is: o A default configuration file is scanned for. A file named webalizer.conf is searched for in the current directory, and if found, it's 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 speci‐ fied, STDIN will be forced. o If an output directory was specified, the program does a chdir(2) to that direc‐ tory in preparation 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 uname(2) 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 previ‐ ous 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 sepa‐ rate 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 Webal‐ izer 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. INCREMENTAL PROCESSING The Webalizer supports incremental run capability. Simply put, this allows processing large log files by breaking them up into smaller pieces, and processing these pieces instead. What this means in real terms is that you can now rotate your log files as often as you want, and still be able to produce monthly usage statistics without the loss of any detail. Basically, The Webalizer saves and restores all internal data in a file named webalizer.current. This allows the program to 'start where it left off' so to speak, and allows the preservation of detail from one run to the next. The data file is placed in the current output directory, and is a plain ASCII text file that can be viewed with any standard text editor. It's location and name may be changed using the IncrementalName configuration keyword. 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 process‐ ing 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 time‐ stamps in two separate 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. REVERSE DNS LOOKUPS The Webalizer fully supports IPv4 and IPv6 DNS lookups, and maintains a cache of those lookups to reduce processing the same addresses in subsequent runs. The cache file can be created at run-time, or may be created before running the webalizer using either the stand alone 'webazolver' program, or The Webalizer (DNS) Cache file manager program 'wcmgr'. In order to perform reverse lookups, a DNSCache file must be specified, either on the command line or in a configuration file. In order to create/update the cache file at run-time, the number of DNSChildren must also be specified, and can be anything between 1 and 100. This specifies the number of child processes to be forked, each of which will perform net‐ work DNS queries in order to lookup up the addresses and update the cache. Cached entries that are older than a specified TTL (time to live) will be expired, and if encountered again in a log, will be looked up at that time in order to 'freshen' them (verify the name is still the same and update its timestamp). The default TTL is 7 days, however may be set to anything between 1 and 100 days. Using the 'wcmgr' program, entries may also be marked as 'permanent', in which case they will persist (with an infinite TTL) in the cache until manually removed. See the file DNS.README for additional information and examples. GEOLOCATION LOOKUPS The Webalizer has the ability to perform geolocation lookups on IP addresses using either it's own internal GeoDB database, or optionally the GeoIP database from MaxMind, Inc. (www.maxmind.com). If used, unresolved addresses will be searched for in the database and its country of origin will be returned if found. This actually produces more accurate Country information than DNS lookups, since the DNS address space has additional gcTLDs that do not necessarily map to a specific country (such as .net and .com). It is possible to use both DNS lookups and geolocation lookups at the same time, which will cause any addresses that could not be resolved using DNS lookups to then be looked up in the data‐ base, greatly reducing the number of Unknown/Unresolved entries in the generated reports. The native GeoDB geolocation database provided by The Webalizer fully supports both IPv4 and IPv6 lookups, is updated regularly and is the preferred geolocation method for use with The Webalizer. The most current version of the database can be obtained from our ftp site (ftp://ftp.mrunix.net/). COMMAND LINE OPTIONS The Webalizer supports many different configuration options that will alter the way the program behaves and generates output. Most of these can be specified on the command line, while some can only be specified in a configuration file. The command line options are listed below, with references to the corresponding configuration file keywords. General Options -h Display all available command line options and exit program. -v Be verbose. Will cause the program to output informational and Debug messages at run-time. -V Display the program version and exit. Additional program specific information will be displayed if verbose mode is also used (e.g. '-vV'), which can be useful when submitting bug reports. -d Debug. Display debugging information for errors and warnings. -i IgnoreHist. Ignore history. USE WITH CAUTION. This will cause The Webalizer to ignore any previous monthly history file only. Incremental data (if present) is still processed. -b IgnoreState. Ignore incremental data file. USE WITH CAUTION. This will cause The Webalizer to ignore any existing incremental data file. By ignoring the incremental data file, all previous processing for the current month will be lost and those logs must be re-processed. -p Incremental. Preserve internal data between runs. -q Quiet. Suppress informational messages. Does not suppress warnings or errors. -Q ReallyQuiet. Suppress all messages including warnings and errors. -T TimeMe. Force display of timing information at end of processing. -c file Use configuration file file. -n name HostName. Use the hostname name. -o dir OutputDir. Use output directory dir. -t name ReportTitle. Use name for report title. -F ( clf | ftp | squid | w3c ) LogType. Specify log type to be processed. Value can be either clf, ftp, squid or w3c format. If not specified, will default to CLF format. FTP logs must be in standard wu-ftpd xferlog format. -f FoldSeqErr. Fold out of sequence log records back into analysis, by treating as if they were the same date/time as the last good record. Normally, out of sequence log records are simply ignored. -Y CountryGraph. Suppress country graph. -G HourlyGraph. Suppress hourly graph. -x name HTMLExtension. Defines HTML file extension to use. If not specified, defaults to html.

CONFIGURATION FILES Configuration files are standard ASCII(7) text files that may be created or edited using any standard editor. Blank lines and lines that begin with a pound sign ('#') are ignored. Any other lines are considered to be configuration lines, and have the form "Keyword Value", where the ´Keyword´ is one of the currently available configuration key‐ words defined below, and 'Value' is the value to assign to that particular option. Any text found after the keyword up to the end of the line is considered the keyword's value, so you should not include anything after the actual value on the line that is not actually part of the value being assigned. The file sample.conf provided with the distribution contains lots of useful documentation and examples as well. General Configuration Keywords LogFile name Use log file named name. If none specified, STDIN will be used. LogType name Specify log file type as name. Values can be either clf, squid, ftp or w3c, with the default being clf. OutputDir dir Create output in the directory dir. If none specified, the current directory will be used. HistoryName name Filename to use for history file. Relative to output directory unless absolute name is given (ie: starts with '/'). Defaults to ´webalizer.hist' in the standard output directory. ReportTitle name Use the title string name for the report title. If none specified, use the default of (in english) "Usage Statistics for ". HostName name Set the hostname for the report as name. If none specified, an attempt will be made to gather the hostname via a uname(2) system call. If that fails, localhost will be used. UseHTTPS ( yes | no ) Use https:// on links to URLS, instead of the default http://, in the 'Top URLs' table. HTAccess ( yes | no ) Enables the creation of a default .htaccess file in the output directory. Quiet ( yes | no ) Suppress informational messages. Warning and Error messages will not be sup‐ pressed. ReallyQuiet ( yes | no ) Suppress all messages, including Warning and Error messages. Debug ( yes | no ) Print extra debugging information on Warnings and Errors. TimeMe ( yes | no ) Force timing information at end of processing. GMTTime ( yes | no ) Use GMT (UTC) time instead of local timezone for reports. IgnoreHist ( yes | no ) Ignore previous monthly history file. USE WITH CAUTION. Does not prevent Incre‐ mental file processing. IgnoreState ( yes | no ) Ignore incremental data file. USE WITH CAUTION. By ignoring the incremental data file, all previous processing for the current month will be lost and those logs must be re-processed. FoldSeqErr ( yes | no ) Fold out of sequence log records back into analysis by treating them as if they had the same date/time as the last good record. Normally, out of sequence log records are ignored. CountryGraph ( yes | no ) Display Country Usage Graph in output report. CountryFlags ( yes | no ) Enable or disable the display of flags in the top country table. FlagDir name Specifies the directory name where the flag graphics are located. If not speci‐ fied, the default is in the flags directory directly under the output directory being used. If specified, the display of country flags will be enabled by default. Using 'FlagDir flags' is identical to using 'CountryFlags yes'. DailyGraph ( yes | no ) Display Daily Graph in output report. DailyStats ( yes | no ) Display Daily Statistics in output report. HourlyGraph ( yes | no ) Display Hourly Graph in output report. HourlyStats ( yes | no ) Display Hourly Statistics in output report. PageType name Define the file extensions to consider as a page. If a file is found to have the same extension as name, it will be counted as a page (sometimes called a pageview). PagePrefix name Allows URLs with the prefix name to be counted as a page type regardless of actual file type. This allows you to treat contents under specified directories as pages no matter what their extension is. OmitPage name Specifies URLs which should not be counted as pages, regardless of their extension (or lack thereof). GraphLegend ( yes | no ) Allows the color coded graph legends to be enabled/disabled. GraphLines num Specify the number of background reference lines displayed on the graphs produced. Disable by using zero ('0'), default is 2. IndexMonths num Specify the number of months to display in the main index (yearly summary) table. Default is 12 months. Can be set to anything between 12 and 120 months (1 to 10 years). YearHeaders ( yes | no ) Enable/disable the display of year headers in the main index (yearly summary) ta‐ ble. If enabled, year headers will be shown when the table is displaying more than 16 months worth of data. Values can be 'yes' or 'no'. Default is 'yes'. YearTotals ( yes | no ) Enable/disable the display of year totals in the main index (yearly summary) ta‐ ble. If enabled, year totals will be shown when the table is displaying more than 16 months worth of data. Values can be 'yes' or 'no'. Default is 'yes'. GraphMonths num Specify the number of months to display in the main index (yearly summary) graph. Default is 12 months. Can be set to anything between 12 and 72 months (1 to 6 years). VisitTimeout num Specifies the visit timeout value. Default is 1800 seconds (30 minutes). A visit is determined by looking at the difference in time between the current and last request from a specific site. If the difference is greater or equal to the time‐ out value, the request is counted as a new visit. Specified in seconds. IndexAlias name Use name as an additional alias for index.*. DefaultIndex ( yes | no ) Enables or disables the use of 'index.' as a default index name to be stripped from the end of URLs. This does not effect any index names that may be defined with the IndexAlias option. MangleAgents num Mangle user agent names based on mangle level num. See the -M command line switch for mangle levels and their meaning. The default is 0, which doesn't mangle user agents at all. StripCGI ( yes | no ) Determines if URL CGI variables should be stripped from the end of URLs. Values may be 'yes' or 'no', with the default being 'yes'. TrimSquidURL num Allows squid log URLs to be reduced in granularity by truncating them after num slashes ('/') after the http:// prefix. A setting of one (1) will cause all URLs to be summarized by domain only. The default value is zero (0), which will dis‐ able any URL modifications and leave them exactly as found in the log file. SearchEngine name variable Allows the specification of search engines and their query strings. The name is the name to match against the referrer string for a given search engine. The variable is the cgi variable that the search engine uses for queries. See the sample.conf file for example usage with common search engines. SearchCaseI ( yes | no ) Determines if search strings should be treated case insensitive or not. The default is 'yes', which lowercases all search strings (treat as case insensitive). Incremental ( yes | no ) Enable Incremental mode processing. IncrementalName name Filename to use for incremental data. Relative to output directory unless an absolute name is given (ie: starts with '/'). Defaults to ´webalizer.current' in the standard output directory. DNSCache name Filename to use for the DNS cache.

Specify zero (0) to disable. CacheIPs ( yes | no ) Cache unresolved IP addresses in the DNS database. Default is 'no'. CacheTTL num DNS cache entry time to live (TTL) in days. Default is 7 days. May be any value between 1 and 100. GeoDB ( yes | no ) Allows native GeoDB geolocation services to be enabled or disabled. Default value is 'no'. GeoDBDatabase name Allows the use of an alternate GeoDB database name. If not specified, the default database will be used. GeoIP ( yes | no ) Allows GeoIP (by MaxMind Inc.) geolocation services to be enabled or disabled. Default is 'no'. If native GeoDB geolocation services are also enabled, then this option will have no effect (and the native GeoDB services will be used).
