See it in action
You say
Set up a monitor for my 'portfolio' app at http://localhost:8080 and its 'postgres-db' Docker container. I want Telegram alerts sent to my bot.
Your agent does
I've generated a monitoring package for 'portfolio'.
- health_monitor.py: Configured with HTTP and Docker checks.
- portfolio-monitor.service/timer: Runs every 5 mins.
- install.sh: Sets up the state dir and systemd units.
Run ./install.sh then python3 health_monitor.py --test to verify your bot token.
About this skill
The problem
Standard monitoring tools often spam your inbox every few minutes when a service is down, leading to alert fatigue and muted notifications. Relying on heavy monitoring stacks for a single self-hosted app or Raspberry Pi is overkill and consumes unnecessary resources.
What it does
- Generates a Python monitor that probes HTTP endpoints and Docker containers on a custom schedule.
- Tracks service status in a local JSON state file to detect transitions.
- Sends Telegram notifications only when a service changes state (down or recovered), remaining silent when healthy.
- Calculates and reports total downtime duration in the recovery alert.
- Provides a complete deployment package including systemd timers, an idempotent install script, and a test mode.
Frameworks & tools
Python, Docker, systemd, Telegram Bot API, and Linux.
Why this beats prompting it yourself
Writing a script is easy, but getting the state-change logic right is difficult. This skill ensures you never get duplicate alerts for the same outage and includes a production-ready systemd configuration that handles environment variables securely through an EnvironmentFile.
Use cases
- Monitor uptime for a personal website or self-hosted dashboard.
- Watch critical Docker containers like databases or Nginx proxies on a Pi.
- Receive immediate Telegram alerts for production outages without the noise of interval pings.
- Track outage history and duration for basic reliability reporting.
Known limitations
Requires a Linux environment with systemd for the scheduling components. Designed for simple up/down status checks rather than complex performance metrics or telemetry.
