PingTower

Real-time server availability monitoring

PingTower checks your servers over HTTP/HTTPS, TCP, and ICMP, keeps latency history, and tells you the moment one goes down or comes back — in the browser, by email, or in Telegram.

C# Go Python React TypeScript PostgreSQL ClickHouse RabbitMQ Redis Docker Traefik Grafana

How it works

Probe Evaluate Store Alert
Each server gets its own goroutine that checks it over HTTP/HTTPS, TCP, or ICMP on schedule Failures in a row and slow responses flip a server to DOWN; a success brings it back UP Every ping — latency, RTT, packet loss, TLS, DNS — goes to ClickHouse in batches Status changes reach the browser, email, and Telegram, with a cooldown against spam
PingTower architecture
Services talk to each other only through RabbitMQ

Getting started

I want to… Go to
run everything locally infra: make -C infra up — storages, broker, migrations and all services
understand the event flow the diagram above and the RabbitMQ topology
integrate over REST api — endpoints, JWT auth, /hubs/monitoring hub

Data model

PingTower ERD
PostgreSQL: servers, ping_settings, users, tokens, telegram_accounts, notification_settings · ClickHouse: server_pings
