<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>

<h3 id="xslt">HTML interface, XSLT generated</h3>
|
|

|
|
|
|
|
|
<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 />
|
|
|
|
|
<strong>We strongly discourage attempts to scrape data from the web interface</strong> as we do not consider this an
|
|
|
|
|
API and will change it, even completely, between versions!<br />
|
|
|
|
|
<strong>The preferred ways are custom XSLT, JSON and raw XML.</strong></p>

<h3 id="json">JSON API, machine readable data</h3>
|
|
|
|
|
|
|
|
|
|
<p>Since version 2.4.0 Icecast includes a basic JSON API (<code>/status-json.xsl</code>) based on a xml2json template by Doeke Zanstra
|
|
|
|
|
(see <code>xml2json.xslt</code>). It exposes the same set of server statistics that are available through the web interface and
|
|
|
|
|
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.
|
|
|
|
|
Also note that not all variables are available all the time and availability may change at runtime due to stream type, etc.</p>

<h3 id="xslt_advanced">Advanced machine readable data, XSLT generated</h3>
|
|
|
|
|
|
|
|
|
|
<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>
