I use gkrellm as my linux monitoring app. I have used it since I started but something I miss is I would like to know what app and destination IPs are causing a traffic spike in my laptop.
Searching a bit a come up with this page with several tools:
Based on my requirement, it seems I need two apps.
- nethogs: For finding out the process triggering the traffic spike
- pktstat: For finding out the IPs involved.
Now it is case of remembering the commands 🙂 But as far as I have tested. It seems they can do the job.
