The primary function of the <var class="product">SirTune</var> product is to provide information
#REDIRECT [[SirTune introduction]]
to User Language programmers to make it easy for them to
improve the performance of their programs.
This is accomplished in two stages:
<ol>   
<li>Data is collected in a running Online or <var>BATCH204</var> region.
This data is obtained by "polling."       
That is, at regular intervals <var class="product">SirTune</var> examines the state of the Online. 
or <var>BATCH204</var> region and records data pertinent to this state.       
<p>
The part of <var class="product">SirTune</var> that collects this data is called the   
<b>data collection</b> portion, which
is integrated with the <var class="product">[[Sirius Mods]]</var> for <var class="product">SirTune</var> versions after 1.5, or which
consists of a separately distributed load module named <b>SIRTUNE</b> 
for <var class="product">SirTune</var> 1.5 and earlier versions. </p>   
 
<li>After this data is collected, it is summarized and presented
in a set of reports that indicate to a User Language programmer the
potential performance problem areas.
These problem areas can generally be refined to an arbitrary level of
detail (for example, individual lines of code in a procedure).
<p>
The part of <var class="product">SirTune</var> that summarizes and produces reports is called the
<b>reporting</b> portion, which consists of a User Language program 
named <var>SIRTUNEREPORT</var>, distributed in the SIRIUS file as part of <var class="product">User Language</var>.</p>
<p>
Pre-7.2 releases required a separate reporting load module 
distributed under the name <var>SIRTUNER</var>.</p>
