connections per VHost

Wowza Streaming Engine
1

Hi,

How can I check total connections per VHost ?

I have the default VHost at port 1935 and a new VHost at port 1936. If I check:

http://:1935

and

http://:1936

Wowza always returns the same value for both ports (server=4).

How Can I check each port’s connections ?

here my VHost.xml

You will have to create a HTTProvider that returns connection count just for that VHost. Use this:

package com.wowza.wms.example.module.http;
import java.io.*;
import com.wowza.wms.http.*;
import com.wowza.wms.logging.*;
import com.wowza.wms.vhost.*;
public class HTTPVHostCount extends HTTProvider2Base {
	public void onHTTPRequest(IVHost vhost, IHTTPRequest req, IHTTPResponse resp) {
		if (!doHTTPAuthentication(vhost, req, resp))
			return;
		String retStr = "<html><head><title>"
				+ "</title></head><body>VHost " + vhost.getName() + " connection count = " + vhost.getConnectionCounter().getTotal() + "</body></html>";
		
		try {
			OutputStream out = resp.getOutputStream();
			byte[] outBytes = retStr.getBytes();
			out.write(outBytes);
		} catch (Exception e) {
			WMSLoggerFactory.getLogger(null).error("HTTPTest: " + e.toString());
		}
	}
}
}

You will need to compile this in the Wowza IDE, then add HTTProvider 2nd to last in the list of HTTProviders of the HostPort:

<HTTPProvider>
	<BaseClass>com.wowza.wms.example.module.http.HTTPVHostCount</BaseClass>
	<RequestFilters>vhostcount*</RequestFilters>
	<AuthenticationMethod>none</AuthenticationMethod>
</HTTPProvider>

Then you can reference like this in a browser:

http://[wowza-address]:1935/vhostcount

Will return:

VHost defaultVHost connection count = 1

Or if you add it your custom VHost in the HostPort that uses port 1936

http://[wowza-address]:1936/vhostcount

Will return:

VHost [CustomVHostName] connection count = 1
