Linux Network Traffic Monitor
Posted by deleted_by_reddit@reddit | linuxadmin | View on Reddit | 2 comments
Hi All,
I am looking for linux internet network traffic monitoring tool. I am aware netstat and few other CLI tools can do this but someone will have to sit to monitor the same. I am looking for some sort of agent which runs inside in the machine and can produce stats on which process is talking to which internet destination.
Any suggestion on this free/paid will be really helpful
-Thanks

We had same problem where CLI tools gave us the data but not in a way that was usable over time. The tricky part is that process level visibility and network flows do not always map cleanly without building something custom.
in our case we used prtg alongside flow monitoring to get a consistent view of traffic patters and then narrowed thing down on the host side when needed.
it didnt give full process to destination mapping out of the box but it made spotting abnormal traffic and drilling into it much faster.

Process level traffic monitoring usually needs more than basic CLI tools. Datadog tends to be highlighted for linking network activity with specific processes using system metrics. That can make it easier to track where connections are going.
