CheckWatch

Read full description

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.

About

Semaphore Remote

Features
Read full description

Semaphore Remote is an app for users who manage automation with Semaphore UI and need quick access to their tasks from a mobile device. Connect directly to your Semaphore server using a personal API token, browse projects and templates, launch new executions, monitor running tasks, and read raw task output when something needs attention. The app is designed for DevOps workflows where speed and simplicity matter. You can open a project, review available templates, start a run, force an execution when needed, check recent tasks, follow active jobs, and quickly jump to fatal messages, errors, warnings, or the last line of a log. Key features: • Connect to Semaphore UI using a personal API token • Browse projects, templates, and task history • Launch tasks from templates • Force task runs when needed • Monitor running, waiting, and pending tasks • Receive local notifications when monitored tasks finish • Read raw task output with line numbers • Search inside logs • Jump quickly to fatal, error, warning, or last-line matches • Share task logs as text files • Supports English and Italian Semaphore Remote does not require an external account and does not use tracking, analytics, or advertising. The app communicates only with the Semaphore server configured by the user. The server URL and API token are stored locally on the device and used only to authenticate requests to your Semaphore UI instance. Note: Semaphore Remote is intended as a mobile companion tool for quick checks and interventions. Local notifications depend on system background behavior and are not a replacement for server-side alerting.
