CheckWatch

CheckWatch is the iOS companion for CheckMK that helps you stay on top of incidents without exposing your monitoring server to the public internet. Receive push notifications for host and service problems, scan a QR code to pair with your CheckMK setup, and review your monitoring state directly from your device. CheckWatch is built for admins, operators, and on-call engineers who need fast signal without unnecessary complexity. What you can do with CheckWatch: - Get real-time push notifications for CheckMK alerts - Keep your CheckMK server behind your firewall by using a secure relay - Pair a device quickly with QR-code setup - View hosts, services, and recent notification history in the app - Acknowledge problems and manage downtime from mobile - Configure quiet hours so alerts stay silent when you are off-call - Use it with CheckMK Raw, Enterprise, Cloud, and MSP editions How it works: 1. Install the CheckWatch plugin on your CheckMK server. 2. Purchase a subscription in the app to activate alert delivery. 3. Scan the pairing QR code from CheckMK. 4. Start receiving alerts on your device. Privacy comes first. CheckWatch does not use analytics or advertising SDKs, and it does not collect your CheckMK credentials. Only the minimum data needed for push delivery and subscription validation is processed. CheckWatch requires a CheckMK server that you manage and the CheckWatch plugin installed on that server.
