<title>Stats module</title>

<para>
The OTRS stats module holds features to track operational statistics and generate custom reports associated with OTRS usage. The OTRS system uses the term "stat" generically to refer to a report presenting various indicators.
</para>

<para>
Proper configuration of the OTRS stats module is associated with a multitude of requirements and considerations. These include the various OTRS modules to be evaluated, user permission settings, indicators to be calculated and their complexity levels, ease of configuration of the stats module, speed and efficiency of calculations, and support of a rich set of output variants.
</para>

<para>
Statistical elements, i.e. files which supplement the functionality of the stats module for specific requirements, can be integrated for calculating complex statistics.
</para>

<section id="stats-usage" >
<title>Handling of the module by the agent</title>

<para>
When signed on as an agent, the navigation bar displays the link "Statistics". This has various submenu options, as shown in Figure.

</itemizedlist>
</para>

<para>
When the stats module is installed, it comes preloaded with a few sample reports imported into the system. These are shown as a list on the Overview page. If the Overview list extends to more than a single page, the agent can browse through the different pages. The list of reports can be sorted as desired, by clicking the desired column header in the list. To generate a particular report, click on the stat number associated with the report in the Overiew list. This brings up the "View" interface for the report.

Agents with write rights can edit an existing report configuration by calling up the edit user interface of the stats module. Alternately, they may create a new report. The associated screens can be reached in the following manner:

If incorrect inputs are entered, the previously processed user interface is displayed again and with information about the incorrect input. This information can be found in the OTRS notification section. The next input user interface is only displayed after the current form has been filled out correctly.

<para>
Whether the results of a statistic are to be cached or not can be setup in the configuration. Cached report results are stored as files in the <filename>var/tmp</filename>directory of the OTRS installation (in most cases <filename>/opt/otrs/var/tmp</filename>).
</para>

<para>
Cached stats can be recognized by the "Stats" prefix.
</para>

<para>
If the data is lost, no major damage is caused. The next time the report is called up, the stats module will not find the file any more and so will generate a new report. Of course this will probably take a little longer to run.

It usually does not make sense to generate reports manually via the command line, as the stats module has a convenient graphical user interface. However, generating reports manually does make sense when combined with a Cronjob.
</para>

Imagine the following scenario: On the first day of every month, the heads of department want to receive a report for the past month. By combining a cronjob and command line call the reports can be sent to them automatically by e-mail.

<section id="stats-static" >
<title>Static stats</title>

<para>
The stats module facilitates the generation of static statistics. For every static stat a file exists in which its content is precisely defined.
</para>

<para>
This way, very complex stats can be generated. The disadvantage is that they are not particularly flexible.

Prior OTRS versions 1.3 and 2.0 already facilitated the generation of stats / reports. Various reports for OTRS versions 1.3 and 2.0 which have been specially developed to meet customers' requirements can be used in recent OTRS versions too.
</para>

<para>The files must merely be moved from the <filename>Kernel/System/Stats/</filename> path to <filename>Kernel/System/Stats/Static/</filename>. Additionally the package name of the respective script must be amended by "::Static".
