WireGuard has quickly become one of the most popular VPN technologies for teams that want a secure, fast, and relatively simple way to connect remote users, offices, cloud networks, and production systems. But there’s a catch: VPN reliability is invisible until it breaks.

If your WireGuard tunnel drops, handshakes stop renewing, peers silently lose connectivity, or routing changes accidentally cut off traffic, you often won’t notice until someone says “I can’t reach the server.” That’s too late—especially when the VPN is part of your production access path, site-to-site connectivity, or internal service mesh.

That’s where WireGuard monitoring comes in.

In this guide, you’ll learn:

• What WireGuard is (and how it works at a practical level)

• What “WireGuard monitoring” actually means

• Why you need to monitor WireGuard services (beyond “is the port open?”)

• The most important WireGuard metrics and signals to track

• Several proven methods for monitoring WireGuard servers and peers

• How to build a complete monitoring setup with uptime checks + performance metrics + alerting

• How Xitoring (Xitoring.com) can monitor WireGuard reliably with minimal effort
