Question

No graph data after starting VPN

VPN Monitoring Ubuntu
Asked by EatingAquamarineScubaDiver

Hi guys, I recently succeeded in configuring a VPN connection for my droplet. I did however lose my health data in the graphs, probably since the DO graph data can’t be obtained from behind the VPN.

I ran into similar SSH-connection problems because of connecting to a VPN, so I’m guessing this is the same problem. To ensure SSH-availability I excluded port 22 from the VPN to be allowed, so maby if anyone knows which port is used by DO for the droplet health data I’m able to allow that connection aswell? I want to state clear that I’m guessing, any more information about the health data monitoring is much appreciated.

Kind regards, R.

Hi there,

I think that the Droplet health metrics stop showing if the monitoring agent can’t reach DigitalOcean’s metrics endpoint. It sends data out over HTTPS (port 443), so if your VPN setup is blocking or rerouting outbound traffic, that’s likely the issue.

Try allowing outbound traffic to metrics.digitalocean.com on port 443 in your VPN config or firewall rules. That should get your graphs back online. Also, good call on excluding port 22 for SSH, same idea applies here, just for monitoring traffic.
