# Getting number of subscribers
|
|
|
|
There's an easy way to display number of clients watching the stream. You need to
|
|
|
|
Set up statistics page at location `/stat`
|
|
```sh
|
|
location /stat {
|
|
rtmp_stat all;
|
|
allow 127.0.0.1;
|
|
}
|
|
```
|
|
|
|
Create a simple xsl stylesheet `nclients.xsl` extracting number of stream subscribers
|
|
```xsl
|
|
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
|
|
|
|
<xsl:output method="html"/>
|
|
|
|
<xsl:param name="app"/>
|
|
<xsl:param name="name"/>
|
|
|
|
<xsl:template match="/">
|
|
<xsl:value-of select="count(//application[name=$app]/live/stream[name=$name]/client[not(publishing) and flashver])"/>
|
|
</xsl:template>
|
|
|
|
</xsl:stylesheet>
|
|
```
|
|
|
|
Set up a location returning number of suscribers
|
|
```sh
|
|
location /nclients {
|
|
proxy_pass http://127.0.0.1/stat;
|
|
xslt_stylesheet /www/nclients.xsl app='$arg_app' name='$arg_name';
|
|
add_header Refresh "3; $request_uri";
|
|
}
|
|
```
|
|
|
|
Use HTTP request `http://myserver.com/nclients?app=myapp&name=mystream` to get the number of stream subscribers. This number will be automatically refreshed every 3 seconds when opened in browser or iframe.
