• If {Stats}{DisableInvocationFromBrowser} config parameter is false (it's false in this installation), the twiki/bin/statistics script can also be executed as a CGI script - just enter the URL in your browser. Examples:

The maximum number of items in columns

There are columns having a list of items. The maximum number of items listed in a column is specified as follows.

Affiliation breakdown of views, saves, and uploads

If you run TWiki in an orgaization, you may want to see division breakdown of topic views, topic saves, and file uploads - in a month, how many topic views are there from the R&D division, the Sales division, etc.

You can have affiliation breakdown at the Topic views, Topic saves, and File uploads columns of WebStatistics and SiteStatistics as follows.

<-- -->

<--statDate-->

<--statViews-->

<--statSaves-->

<--statUploads-->

<--statTopViews-->

<--statTopViewers-->

<--statTopContributors-->

Affiliation breakdown is turned off by default. To turn it on, you need to do two things.

1. Provide getAffiliation($cUID) object method in the current user mapping handler. It's supposed return the affiliation (division, department, etc.) of the $cUID. If the affiliation is unknown, it returns undef.
2. Set {Stats}{Breakdown} configuration papameter true by putting the following line in lib/LocalSite.cfg.

   $TWiki::cfg{Stats}{Breakdown} = 1;
   

Excluding some webs from WebStatistics update

You can exclude webs from WebStatistics update by specifying {Stats}{ExcludedWebRegex} config parameter as follows.

$TWiki::cfg{Stats}{ExcludedWebRegex} = '^(Trash(x\d+x)?\d*|Sandbox\d*)\b';

You may wonder when this is needed.

There are webs not worth updating WebStatistics such as the Trash web. When a web is deleted, it becomes a subweb of the Trash web. By default, not only the Trash web but also subwebs of the Trash web are subject to WebStatistics update.

On a large TWiki site, you may have dozens of Trash webs - you may rotate Trash webs and you may be UsingMultipleDisks (each disk requires its own Trash - e.g. Trashx1x and Trashx2x). If you have Trash, Trash1, ..., Trash10 for rotation and if you use 3 disks for TWiki, you end up having 33 Trashes.

Preventing WebStatistics and SiteStatistics from growing big

WebStatistics topics grow in size every month. By default you have only 10 lines per month, but you may have a lot more. If so, in 5 years, WebStatistics gets really big. Besides, if you run the statistics script every day, you increase the revision of each WebStatistics by one every day. If a topic has hundreds of revision, some operations such as getting the original creator of the topic takes long.

There is an option to prevent the boundless growth of WebStatistics. If you set $TWiki::cfg{Stats}{TopicPerYear} true, the statistics script writes the result to WebStatisticsYYYY where YYYY is the current year (e.g. WebStatistics2024) instead of WebStatistics. The parameter is false by default.

• If TWiki:Plugins/RedirectPlugin is installed, viewing WebStatistics causes redirection to the WebStatisticsYYYY of the year. Otherwise, WebStatistics shows links to WebStatisticsYYYY topics.
• After you change {Stats}{TopicPerYear} to true but before you run the statistics script, you should run twiki/tools/switch2yearlystats to rename WebStatistics of all webs to WebStatisticsYYYY of the year. In case WebStatistics is not in the same format as its current template, it's renamed to WebStatistics0000.

The description above is applied to Main.SiteStatistics as well. If {Stats}{TopicPerYear} is true:

• The site-wide statistics are written to Main.SiteStatisticsYYYY of the year instead of Main.SiteStatistics
• Main.SiteStatistics shows the list of Main.SiteStatisticsYYYY topics or redirects to the latest one depending on the availability of RedirectPlugin.
• twiki/tools/switch2yearlystats renames Main.SiteStatistics to Main.SiteStatisticsYYYY of the year or Main.SiteStatistics0000.

Upgrade from pre 6.0

Statistics topic conversion

There are several changes made to WebStatistics and SiteStatistics. If existing statistics topics are kept as they are, topic update by the statistics script doesn't work well. By running tools/convert_stats_twiki6 after upgrade, all statistics topics are converted for the current version of statistics.

Top Contributors on SiteStatistics

The number of contributors listed on the "Top Contributors" column on SiteStatistics is specified by {Stats}{SiteTopContrib}. Prior to TWiki 6.0, it was specified by {Stats}{TopContrib}. If you have a custom {Stats}{TopContrib} value, you need to set {Stats}{SiteTopContrib} as well. Otherwise, the number of "Top Contributors" on SiteStatistics becomes the default value, which is 10.

• SitePermissions lists the permissions settings of the webs on this TWiki site

• You can define a separate {SMTP}{SENDERHOST} configure setting to set the mail sender host - some SMTP installations require this.
• If you are using SELinux (Security-Enhanced Linux) you might need to configure it to allow TWiki to send e-mails:
  $ sudo setsebool -P httpd_can_sendmail on
$ sudo setsebool -P httpd_can_network_connect on

TWiki also generates overall site usage statistics in Main.SiteStatistics (do not create that page, it is created automatically based on SiteStatisticsTemplate). On a monthly basis, the following items are recorded using system data and TWiki log data across all webs: Number of webs, number of topics, number of attachments, number of topic views, number of topic updates, number of files uploads, data size, pub size, disk use, number of users, number of groups, number of plugins installed compared to total number of plugins available, and the 10 top contributors.

• You can automatically generate usage statistics for the whole site and all webs. To enable this:

• • Call the twiki/bin/statistics script from a cron job - once a day is recommended. This will update the SiteStatistics and the WebStatistics topics in all webs.
  • Attention: The script must run as the same user as the CGI scripts are running, such as user nobody or www-data. Example crontab entry:
    0 0 * * * (cd /path/to/twiki/bin; ./statistics >/dev/null 2>&1)

• The twiki/bin/statistics script can also be executed as a CGI script - just enter the URL in your browser. Examples:

• • Update Nov 2024 for Main web:
    /do/statistics/Main?logdate=2024-11
  • Update Nov 2024 for the ProjectX, ProjectY and ProjectZ webs:
    /do/statistics?logdate=2024-11;webs=ProjectX,ProjectY,ProjectZ

Backup and Restore

TWiki has a solution to backup, restore and upgrade TWiki sites. It can be used via browser and on the command line. The BackupRestorePlugin is pre-installed in TWiki-5.1 and later releases; it can be installed in older TWiki releases as low as TWiki-2001-09-01 (Athens Release) to easily create a backup that can be restored on a new TWiki release. This offers an easy upgrade path for TWiki. See also TWikiUpgradeGuide.

• • Make sure variable {Log}{view}, {Log}{save} and {Log}{upload} are set in configure. This will generate log file entries (see below).

TWiki Site Tools

WebRss and WebAtom - news feeds on recent changes

You can point your news reader at WebRss and WebAtom to find out what is new in a TWiki web. WebRssBase and WebAtomBase have the details. Like WebChanges, this is based on a %SEARCH{}%.

• • NOTE: geturl.pl will do a TWiki CGI request as the TWikiGuest user, so if you use this workaround, the WebStatistics topics you are updating will have to be writable by TWikiGuest.

• • Update current month for Main web only:
    /do/statistics/Main
  • Update Nov 2024 for Main web:
    /do/statistics/Main?logdate=202411

Help with crontab

The crontab command is used to schedule commands to be executed periodically.

• Wikipedia.org:Crontab - crontab documentation
• pycron - crontab for Windows

• • There is a workaround in case you can't run the script as user nobody : Run the utility twiki/tools/geturl.pl in your cron job and specify the URL of the twiki/bin/statistics script as a parameter. Example:
    0 0 * * * (cd /path/to/twiki/tools; ./geturl.pl mydomain.com /urlpath/to/twiki/bin/statistics >/dev/null 2>&1)

./statistics -logdate 200605 -webs TWiki,Sandbox

• • Update current month for all webs you have access to:
    /do/statistics

• • Update Nov 2024 for Main web:
    /do/statistics/Main?logdate=202411
  • Update Nov 2024 for the ProjectX, ProjectY and ProjectZ webs:
    /do/statistics?logdate=202411;webs=ProjectX,ProjectY,ProjectZ

Configuring for automatic operation

• • Make sure variable {Log}{view}, {Log}{save} and *{Log}{upload} in are set in configure. This will generate log file entries (see below).

• • Attention: The script must run as the same user as the CGI scripts are running, which is user nobody on many systems. Example crontab entry:
    0 0 * * * (cd /path/to/twiki/bin; ./statistics >/dev/null 2>&1)
  • There is a workaround in case you can't run the script as user nobody : Run the utility twiki/bin/geturl in your cron job and specify the URL of the twiki/bin/statistics script as a parameter. Example:
    0 0 * * * (cd /path/to/twiki/bin; ./geturl mydomain.com /urlpath/to/twiki/bin/statistics >/dev/null 2>&1)

Generating statistics manually by URL

• • Update current month for all webs:
    /do/statistics
  • Update current month for Main web only:
    /do/statistics/Main
  • Update January 2000 for Main web:
    /do/statistics/Main?logdate=202411

Log Files

• The log file is defined by the {LogFileName} setting in configure

• Example path name: twiki/logs/log202411.txt

• Actions are logged if enabled in configure by the {Log}{action} flags

E-mail

Configuring outgoing mail

• Net::SMTP can be easily disabled (if there is an installation error) by setting SMTPMAILHOST in TWikiPreferences to an empty value.

• You can set a separate SMTPSENDERHOST variable to define the mail sender host (some SMTP installations require this).

Setting the automatic e-mail schedule

For Unix platforms: Edit the cron table so that mailnotify is called in an interval of your choice. Please consult man crontab of how to modify the table that schedules program execution at certain intervals. Example:

For ISP installations: Many ISPs don't allow hosted accounts direct cron access, as it's often used for things that can heavily load the server. Workaround scripts are available.

On Windows: You can use a scheduled task if you have administrative privileges. TWiki:Codev/CronTabWin is a free scheduler for Windows.

Site Permissions

• TWikiAccessControl describes how to restrict read and write access to topics and webs, by users and groups
• SitePermissions lists the permissions settings of the webs on this TWiki site

Web Changes Notification Service

Each TWiki web has an automatic e-mail notification service that sends you an e-mail with links to all of the topics modified since the last alert.

Tip: Instead of subscribing here, it is easier to "watch" topics of interest. Watching topics gives you the choice of immediate notification or digest notification.

Users subscribe to email notifications using their WikiName or an alternative email address, and can specify the webs/topics they wish to track, Whole groups of users can also be subscribed for notification.

The general format of a subscription is:

three spaces * subscriber [ : topics ]

Where subscriber can be a WikiName, an E-mail address, or a group name. If subscriber contains any characters that are not legal in an email address, then it must be enclosed in 'single' or "double" quotes. Please note that the guest user TWikiGuest does not have an email address mapped to it, and will never receive email regardless of the configuration of that user.

topics is an optional space-separated list of topics:

• ... without a Web. prefix
• ...that exist in this web.

• Using wild-card character in topic names - You can use * in a topic name, where it is treated as a wildcard character. A * will match zero or more other characters - so, for example, Fred* will match all topic names starting with Fred, *Fred will match all topic names ending with Fred, and * will match all topic names.
• Unsubscribing to specific topics - Each topic may optionally be preceded by a '+' or '-' sign. The '+' sign means "subscribe to this topic". The '-' sign means "unsubscribe" or "don't send notifications regarding this particular topic". This allows users to elect to filter out certain topics. Topic filters ('-') take precedence over topic includes ('+') i.e. if you unsubscribe from a topic it will cancel out any subscriptions to that topic.
• Including child-topics in subscription - Each topic may optionally be followed by an integer in parentheses, indicating the depth of the tree of children below that topic. Changes in all these children will be detected and reported along with changes to the topic itself. Note This uses the TWiki "Topic parent" feature.
• Subscribing to entire topic ("news mode") - Each topic may optionally be immediately followed by an exclamation mark ! and/or a question mark ? with no intervening spaces, indicating that the topic (and children if there is a tree depth specifier as well) should be mailed out as complete topics instead of change summaries. ! causes the full topic to be mailed every time even if there have been no changes, and ? will mail the full topic only if there have been changes. One can limit the content of the subscribed topic to send out by inserting %STARTPUBLISH% and %STOPPUBLISH% markers within the topic. Note that "news mode" subscriptions require a corresponding cron job that includes the "-news" option (see details).

Examples: Subscribe Daisy to all changes to topics in this web.

   * daisy.cutter@flowers.com

   * daisy.cutter@flowers.com : Web*

   * DaisyCutter: Petal* (1) WeedKillers (3) Pretty*Flowers

   * StarTrekFan: Star* - *Wars - *sInTheirEyes - *shipTroopers

   * daisy@flowers.com: NewsLetter?

   * buttercup@flowers.com: NewsLetter! (1)

   * GardenGroup: AllNewsLetters? (3)
   * petunia@flowers.com: - ManureNewsLetter

   * 'IT:admins' : Web*

A user may be listed many times in the WebNotify topic. Where a user has several lines in WebNotify that all match the same topic, they will only be notified about changes that topic once (though they will still receive individual mails for news topics).

If a group is listed for notification, the group will be recursively expanded to the e-mail addresses of all members.

Warning: Because an email address is not linked to a user name, there is no way for TWiki to check access controls for subscribers identified by email addresses. A subscriber identified by an email address alone will only be sent change notifications if the topic they are subscribed to is readable by guest users. You can limit what email addresses can be used in WebNotify, or even block use of emails altogether, using the {MailerContrib}{EmailFilterIn} setting in =configure.

Tip: List names in alphabetical order to make it easier to find the names.

Note for System Administrators: Notification is supported by an add-on to the TWiki kernel called the MailerContrib. See the MailerContrib topic for details of how to set up this service.

Note: If you prefer a news feed, point your reader to WebRss (for RSS 1.0 feeds) or WebAtom (for ATOM 1.0 feeds). Learn more at WebRssBase and WebAtomBase, respectively.

• • Make sure variable $doLogTopicView, $doLogTopicSave and $doLogTopicUpload in TWiki.cfg are set. This will generate log file entries (see below).

• • Attention: The script must run as the same user as the CGI scripts are running, which is user nobody on many systems. Example crontab entry:
    0 0 * * * (cd /path/to/TWiki/bin; ./statistics >/dev/null 2>&1)

Log File Details

TWiki generates monthly log files which are used by the statistics

• The log directory is defined by the $logDir variable in TWiki.cfg
• The file name is log<year><month>.txt
• Example path name: twiki/data/log202411.txt
• Each access gets logged as:
  | <time> | <wikiusername> | <action> | <web>.<topic> | <extra info> | <IP address> |
• Example log entry:
  | 01 Nov 2024 - 01:04 | Main.TWikiGuest | view | TWiki.WebRss |  | 66.124.232.02 |
• Actions are logged if enabled in TWiki.cfg by the $doLogTopic<action> flags
• Logged actions:

  Script	Action name	Extra info
  attach	attach	when viewing attach screen of previous uploaded attachment: filename
  changes	changes
  edit	edit	when editing non-existing topic: (not exist)
  register	register	E-mail address
  save	save	when replacing existing revision: repRev 1.3 when user checks the minor changes box: dontNotify
  search	search	search string
  rdiff	rdiff	1.4 1.3
  rename	rename	when moving topic: moved to Newweb.NewTopic
  rename	move	when moving attachment: Attachment filename moved to Newweb.NewTopic
  upload	upload	filename
  view	view	when viewing non-existing topic: (not exist) when viewing previous topic revision: r1.3

TWiki Site Tools

• You can create a WebNotify link using TWikiVariables with %NOTIFYTOPIC%

TWiki handles WebNotify entries that include the WikiName of a user or a TWikiGroup and an optional e-mail address. Example entries in WebNotify:

	 * Main.FredBloggs
	 * Main.FredBloggs - secondary@home.com
	 * Main.EngineeringGroup

The first entry is the default form, the notification gets sent to the e-mail address specified in the user's home page. The second entry lists an alternative e-mail address. The third entry specifies a group, the notification gets sent to each member of the group.

You can also use %MAINWEB% instead of Main, but this is not necessary even if you have renamed the main web by configuring $mainWebname in TWiki.cfg.

mailnotify also relies on two hidden files in each TWiki/data/[web] directory: .changes and .mailnotify. Make sure both are writable by your web server process. .changes contains a list of changes; go ahead and make this empty. .mailnotify contains a timestamp of the last time notification was done.

• Net::SMTP can be easily disabled (ex: if there is an installation error) by setting SMTPMAILHOST in TWikiPreferences to an empty value.

• You can set a separate SMTPSENDERHOST variable to define the mail sender host (some SMTP installations require this).

• You can create a WebNotify using TWikiVariables with %NOTIFYTOPIC%

• You can create a WebStatistics link using TWikiVariables with %STATISTICSTOPIC%

WebChanges

To check for the most recently edited topics while on-site, use the WebChanges link, usually located on the upper toolbar. It lists the most recently modified topics, newest first, along with the first couple of lines of the page content.

This is simply a preset SEARCH. The number of topics listed by the limit parameter.:

%SEARCH{".*" web="TWiki" regex="on" nosearch="on" order="modified" 
reverse="on" limit="50"}%

WebIndex

WebIndex lists all web topics in alphabetical order, with the first couple of lines of text. This is simply a preset SEARCH:

%SEARCH{"\.*" scope="topic" regex="on" nosearch="on"}%

TWikiSiteTools

Utilities for searching, navigation, and monitoring site activity

Overview

TWikiSiteTools include utilities for navigating, searching and keeping up with site activity. Preferences can be configured by web or site-wide. You are currently in the TWiki web.

Monitoring Topic Changes

TWiki provides two highly configurable, automated site monitoring tools, WebNotify, to email alerts when topics are edited, and WebStats, to generate detailed activity reports.

WebNotify Recent Changes Alert

Each TWiki web has an automatic email alert service that sends a list of recent changes on a preset schedule, like once a day. Users can subscribe and unsubscribe using WebNotify in each web.

Setting Up WebNotify

The Perl script mailnotify is called by a deamon in regular intervals. The script sends an automated email to subscribed users if topics were changed in a web within last interval.

Configuring Outgoing Mail

TWiki will use the Net::SMTP module in case it is installed on your system. You need to specify the SMTPMAILHOST variable in TWikiPreferences.

You can use an external mail program like sendmail in case the Net::SMTP module is not installed. In this case specify the $mailProgram in twiki/bin/TWiki.cfg.

Setting the Automatic Email Schedule

For Unix platforms: Edit the cron table so that mailnotify is called in an interval of your choice. Please consult man crontab of how to modify the table that schedules program execution at certain intervals. Example:

% crontab -e
15,45 * * * * (cd ~twiki/public_html/bin; ./mailnotify -q)

For ISP installations: Many ISPs don't allow hosted accounts direct cron access, as it's often used for things that can heavily load the server. Workaround scripts are available.

On Windows NT/2000: You can use a scheduled task if you have administrative privileges. Note: AT on an NT machine is pretty limited. Microsoft lists several third-party replacements (as of 2001-11-20, none of them free).

WebChanges

To check for the most recently edited topics while on-site, use the WebChanges link, usually located on the upper toolbar. It lists the _ most recently modified, newest first, along with the first couple of lines of the page content.

How does it work?

WebStatistics Site Usage Log

You can generate a listing manually, or on an automated schedule, of visits to individual pages, on a per web basis. Compiled as a running total on a monthly basis. Includes totals for Topic Views, Topic Saves, Attachment Uploads, Most Popular Topics with number of views, and Top Contributors showing total of saves and attachment uploads. Previous months are saved.

Configuring for Automatic Operation

• You can automatically generate usage statistics for all webs. To enable this:
  • Make sure variable $doLogTopicView, $doLogTopicSave and $doLogTopicUpload in TWiki.cfg are set. This will generate log entries in file twiki/data/log<date>.txt .
  • The WebStatistics topic must be present in all webs where you want to have statistics. You can use the topic in the Main web as a template.
  • Call the twiki/bin/statistics script from a cron job, once a day is recommended. This will update the WebStatistics topics in all webs.
  • Attention: The script must run as the same user as the CGI scripts are running, which is user nobody on most systems. Example crontab entry:
    0 0 * * * (cd /path/to/TWiki/bin; ./statistics >/dev/null 2>&1)
  • There is a workaround in case you can't run the script as user nobody : Run the utility twiki/bin/geturl in your cron job and specify the URL of the twiki/bin/statistics script as a parameter. Example:
    0 0 * * * (cd /path/to/TWiki/bin; ./geturl mydomain.com /urlpath/to/TWiki/bin/statistics >/dev/null 2>&1)

Generating Statistics Manually by URL

• The twiki/bin/statistics script can also be executed as a CGI script, just enter the URL in your browser. Examples:
  • Update current month for all webs:
    http://mydomain.com/twiki/bin/statistics
  • Update current month for Main web only:
    http://mydomain.com/twiki/bin/statistics/Main
  • Update January 2000 for Main web:
    http://mydomain.com/twiki/bin/statistics/Main?logdate=200001
