Hello All ,
I am looking for a solution on how can we monitor the traffic received on UDP ports ( preferably through Nagios)
As per our setup , we are using Data Diode for highly secure unidirectional flow . There is a backend third party application which is sending data and it comes through data diode to the top layer on specific UDP port ( dual node active-active setup for high availability ) .
Now sometimes we fall in the situation when one of the data diode leg stop working which ultimately impacts the overall data flow .
