    Hey Robert,<br>
    <br>
    sorry for my late reply. Your messages are flagged as spam here
    (Google Mail)<br>
    Yes, check_mk and nagios are free and open source.<br>
    It is more likely a system health monitor (is port 5060 reachable
    and what is the answer => active checks)<br>
    And it's reading from standard unix tools (like ps, free - CPU usage
    => passive checks)<br>
    It saves that data in a history (and builds fancy graphs) and sends
    me mails / SMS messages when some service is down.<br>
    <br>
    I've attached a screenshot from the webinterface.<br>
    <br>
    So check_mk can't monitor RTP traffic, but you can write your own
    checks in Python (at least the webview)<br>
