Run agents where cloud checks can't reach
An external ping only sees your front door. A ConnLog agent runs inside the box — behind NAT, in private subnets, on bare metal — using outbound HTTPS only.
- Single static Rust binary — no runtime, no Docker
- Outbound HTTPS only — no inbound ports to open
- Installs as a systemd service and auto-updates
Works on any modern Linux distro — x86_64 & aarch64
Alerting
Get alerted before your users notice
When a server goes silent or crosses a threshold, ConnLog emails you within seconds — and emails you again, automatically, the moment it recovers.
- Silence detection from missed heartbeats
- CPU, RAM, disk and load threshold alerts
- Automatic recovery emails — no alert spam
