rtsp monitoring

Hi!

 

 

I found a description of a monitor to RTSP. However I am having trouble interpreting it. This is the monitor:

 

 

monitor RTSP-TCP {

 

defaults from tcp

 

recv "200 OK"

 

send "OPTIONS /sample_100kbit.mp4 RTSP/1.0\nCSeq: 1\n\n"

 

}

 

 

Does it mean that i have to configure a TCP monitor, fill the send string field with OPTIONS /sample_100kbit.mp4 RTSP/1.0\nCSeq: 1\n\n and the rcv string field with 200 OK?

 

 

Thanks in advance

    I have added the refered monitor with receive string = 200 OK.

     

    However when I stop the associated publishing point on Windows Media server, the member status remain green.

     

     

    When I sniff the network I see that after the string is sent, I allways get 200 OK. The difference comes in subsequent packets.

     

     

    How can I differentiate the two Publishing Point status?

    You would want to configure the receive string to be a string found only in good responses. There is a limit to how many bytes the monitoring daemon, bigd, will check for the receive string. I searched on AskF5, but couldn't find the value. I think it's around 1000 bytes though.

    hoolio is correct, set your Receive string to a value that is found in a subsequent packet only when the server is healthy.

     

     

    LTM will examine up to 5MB (5120 bytes) of the response for a match. AskF5 solution 3451 has the details: Click here
