Monitoring UDP ports

Hi All,

I am trying to evaluate this software for my company, in doing so i have installed the Freeware version, (as it is likely to take me more than 15 days to correctly configure and test this site.

In doing so, i was unaware that it would disable my ability to run External program checks.

I was using a tool from M$ to scna UDP ports, portqry.exe, which worked well.

Since i can no long use this, does anyone have any ideas ho i might check if UDP ports are in a listening state without using externel programs? I need this feature to monitor Software Licensing services.

    Replace the installed s-server.exe with this one:

    Where should this appear?

    I thought it would be an option like TCP is. I am not seeing it though.

    Not sure what you are actually asking AZChris,

    But we will start here:

    Create a new Monitoring rule and under "What do you wnat to monitor?" select:

    APM: Application performance & availability checks

    And then att he bottom of the list select:

    EXTERNAL: enables you to execute custom checks and be alerted on it.

    then you can monitor via whatever program you wish.

    Hi Thanks for responding.

    The initial question was to monitor udp ports without using an external app. I thought maybe that was put into the the monitor options just like the TCP option. If i need to use an external app to monitor it, then I will go that route, as you have outlined.

    Hey Chris,

    I think you will need to use the external tool...

    Good Luck ;)
