OpenVPN bandwidth monitoring
Hi Guys, I have added the monitoring tools, bandwidthd and also ntopng to monitor the openVPN subnet, but without succes. Is there any way to monitor my OpenVPN subnet with some other tool ?
Any idea is well appreciated.
Thanks a lot
Yes you can use a real separate monitoring system called SolarWinds. It's enterprise class minimum 150 objects license. Then you monitor the performance of the network used by openvpn with NPM. And with SolarWinds SAM you monitor the cpu processes for that openvpn software or any software on any OS.
There are many competitors for monitoring systems but my experience it's the best and most comprehensive I've ever used. Nothing comes to par with SolarWinds suite. And I don't work or get paid by them. I just love their software.
Splunk, Nagios, come to mind but they aren't as mature a product.
You could also look at your switch or vlan stats if you have managed switches and route that service thru a specific port to connect to the openvpn server. It's a long shot but that's a free way to do it and low end.
Thanks a lot for suggestions, but I wanted to know if there is any way on the PfSense to monitor my bandwidth of the existing OpenVpn connections. (ntopng is working but it is showing only the public IP address of the clients, I will have a lot of them).
I`m thinking to implemented a Nagios solution for this monitoring if there is no other solution.
If you need the granular data of per session then it's custom code, db to store data and API calls from openvpn, if it even exists for openvpn.
Nagios could give you per IP bandwidth usage. Keep in mind, if someone connects from a router, a cafe or college public IP then many people usage will be under 1 IP. So you won't get a per session number.
If somehow the newest version of Nagios has this capability please let the community here know as I've moved on from that utility long ago.
