How can we monitor traffic on UDP port coming through Data diode ? 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 .
As per current situation , I am using a customised shell script which uses TCPDUMP on UDP ports to ensure we are receiving data on both leg of Data daiode . The script use to monitor the TCPDUMP traffic every 15 min and if no data received in last 15 min then sleep for 10 min and check again.
If no data received while second check then raise an alarm via Nagios . |

Their new naming convention takes some getting used to, but once it was fully adopted, it improved economy, flexibility, and functionality.

Versioning question for a major upgrade project Project to be performed in 2 equally complex phases, each phase to deliver to production about 4 months apart. The project has been identified as 8.0.

DevOps tools can be strategic assets, but they are not as important as established CM standards and process. It's up to us as practitioners to ensure that the DevOps tool chain implementation supports the corporate CM policy.
