Gateway Watchdogv1.0.0

A company running an internal API gateway for microservices needs to ensure high availability. The watchdog automatically detects and restarts the gateway with backoff and cooldown, preventing service disruptions for critical HTTP services.

In edge deployments with limited supervision, the watchdog runs locally to maintain gateway connectivity. Its boot grace period avoids false restarts during startup and progressive retries allow temporary network glitches to resolve.

MSPs managing multiple customer gateways can deploy this watchdog on each service node. The cooldown mechanism prevents restart loops, helping maintain service-level agreements with reliable gateway health checks.

Hobbyists running a home server with a gateway service for remote access benefit from automated recovery. The watchdog uses lightweight Bash and logs to a single file, making it easy to monitor without complex tools.

SaaS providers with a gateway component in their stack can embed this watchdog as a resilience layer. The combination of HTTP, port, and stale PID checks prevents unnecessary restarts while keeping the gateway responsive.

Package the watchdog as a plugin or integration for popular monitoring platforms (e.g., Prometheus exporter). Charge a subscription fee for premium features like advanced alerts or multi-gateway dashboards.

Offer consulting and customization of the watchdog for enterprise clients with complex gateway setups. Provide deployment, tuning, and 24/7 incident response for a retainer fee.

Keep the watchdog script open-source, but sell a companion desktop/mobile app for remote monitoring and overrides. The app provides a GUI for logs, status, and manual restarts, with in-app purchases for extended history.
