Monitoring the health of NPM

[Australian]

Hi all,

Looking for some help with monitoring Nginx Proxy Manager after some odd behaviour.

I am fine with troubleshooting the Server & Platform that NPM sits on but i am not as experienced with NPM itself and was hoping someone could give me a steer.

There have been a few instances where the server becomes unreachable but yet still kind of works. I cannot browse to the NPM Dashboard, cant RDP or Teamviewer onto the server and cant even open the Console on VMware but CAN SSH onto it and the proxied hosts are... proxied fine. A magic reboot fixes it.

So the Network Proxy Manager is running on Ubuntu Server 24.04 which is a VM running on VMware ESXi 8
Connectivity via OpenSSH, RDP and also Teamviewer as a backup way of getting onto my network when i am outside and if for whatever reason OpenVPN is not available.

I am using PRTG for Monitoring.

Any ideas on what i should be monitoring within NPM ??
