Monitoring Solved.

The native iOS companion for CheckMK.
Real-time alerts on your device via a secure, private relay.

System Architecture

Outbound-Only Plugin

Python plugin connects via notification rule. No inbound ports required on your monitoring server. Secure mapping via license key.

Zero-Knowledge Relay

Relay validates licenses and forwards payload to APNs. Payload is transient; no notification data is persisted on our servers.

~/var/log/notify.log

[20] PING CRITICAL - 100% packet loss
