<h2>Overview</h2>
<p>Icecast provides extensive run time statistics. Both in the form of active connection numbers and cumulative counters (since server startup or respectively source connection startup).</p>
<a name="xslt"></a>
<h2>HTML interface, XSLT generated</h2>
<p>Icecast comes with a basic, XHTML web interface. It exposes a basic set of server statistics that should fulfil basic user needs. If so desired the files in web-root can be customized to contain more or less information (see section on raw XML data below). <br/>
We strongly discourage attempts to scrape data from this interface as we do not consider this an API and will change it, even completely, between versions. The preferred ways are custom XSLT, JSON and raw XML.</p>
<a name="xslt_advanced"></a>
<h2>Advanced machine readable data, XSLT generated</h2>
<p>Icecast uses the very powerful libXSLT engine to transform its internal raw statistical data into custom tailored interfaces. Many people have written custom XSLT code that produces e.g. plain text "now playing", XSPF, VCLT, munin interface data, etc.</p>
<p>Since version 2.4.0 Icecast includes a basic JSON API (/status-json.xsl) based on a xml2json template by Doeke Zanstra (see xml2json.xslt). It exposes a basic set of server statistics that should fulfil basic user needs. The intention is to not break backwards compatibility of this interface in the future, still we recommend to design robust software that can deal with possible changes like addition or removal of variables.</p>
