My goal is simply at the end of the month to know that Acme Co's VM used n GB of data.Overview of ntopng Network Monitoring System Here is my current configuration at /etc/ntopng/nf. Or do I need to specifically disable them somehow? Lastly, I've disabled all DNS features. I'm assuming that the web server component is either idle or disabled as I have not set any values for those params. I'm actually only interested in the INBOUND traffic as well, as uploads are not billable, so I've already set the -capture-direction=1 flag to only track RX traffic (from Bucket to VM). I'm ONLY interested in the connection described above, so is there a way to apply a filter to only track connections from a certain origin rather than tracking ALL traffic? I've noticed that the overhead of ntopng is not inconsequential, and these are not resource rich VM's, so I'd like to lessen it's memory/resource footprint if I can. I've installed ntopng community edition on the VM and right now it's dumping all it's data into a MySQL database. I need to be able to track client data usage between their VM and an S3 compatible object storage bucket (accessed via https).
