Openvpn monitoring

**CMK version:2.2
**OS version:ubuntu 22.04

I’m trying to monitor the vpn usage of the server, but it seems it currently only monitors the currently connected user and needs a service discovery after each user has connected.
At least currently it only sees one service which is specifically my vpn connection.

Also won’t this cause the issue that when user disconnects i loose all the data of that users vpn usage as checkmk doesn’t see the service anymore ?

Hi @liliang

That’s correct, the Check is only checks the client connections. You can read more about that here:

Normally you use this check to monitor site 2 site tunnels.

To troubleshoot specific VPN issues, you won’t find a suitable out-of-the-box check for that. Because there are many possible origins for issues. Especially in networking.

I would suggest monitoring the round trip time with a ping check and also check for packet loss.
If it is End users then there are many possible reasons why you have issues that you can’t even influence in the end (slow Wi-Fi at home, not enough bandwidth and so on). But with Ping checks you should be able to get more insights in the end.

Hope this helps.

Best regards
