Know about the problem before your users do.
Sentinel watches your servers, containers and services, and explains what's wrong when something breaks: the likely cause and the first steps, in plain language. It never changes production on its own.
The problem
Outages get reported by customers, disks fill up, certificates expire and logs pile up unread. Classic monitoring sends too many alerts, so the important one gets missed.
How it works
Inventory
Servers, containers, domains, certificates and backups, documented once.
Watch
Health checks, resources, certificate expiry, backup results and suspicious logins.
Explain
Alerts summarised with the likely cause and first steps, with the noise filtered out.
Act with approval
Runbook actions prepared in advance, run only when you approve them.
What you get
- Monitoring of your servers, containers and services
- Alerts by email, Telegram or your team chat
- Runbooks for the incidents that matter
- A regular health report
Built with
Docker, Proxmox, Cloudflare, watchdog scripts, n8n, Telegram or email
A good fit if
- You learn about outages from your customers
- Nobody owns monitoring full time
- You run self-hosted servers or containers
Our own infrastructure, more than twenty containers running sites, agents and pipelines, is watched by the same kind of watchdog scripts with daily reports, backed by 16 years of enterprise infrastructure operations.
