Sentinel guide
Website Uptime Monitoring with Real Help
Four useful kinds of check
A website can return a successful response while showing an error page, and a server can be reachable while the service you need is not listening. Sentinel separates these cases with four check types: a website check for an HTTP response, a word-on-a-page check for expected content, a port check for a specific network service, and a ping check for basic reachability. Choose the check that matches what you actually need to know.
Intervals built around your plan
Checks run on the interval agreed for your setup during early access. Sentinel does not alert on a single failed request. It waits for two failed checks before notifying you, which helps keep a transient connection blip from waking the team while still surfacing a real outage quickly. Alerts explain the observed result and can go to Telegram, email, Slack, Microsoft Teams, Discord or your webhook.
A status page people can use
For customers or colleagues who need visibility, publish a public status page with the services you choose to show. It gives people a place to check during an incident instead of sending the same question to your team repeatedly.
More than a simple uptime checker
A basic uptime checker answers only whether one URL responded. Sentinel connects website checks with server signals, ports, security hygiene and published software warnings, then puts the context into a message a human can act on. It is still not an audit or a guarantee that every problem will be found. It is a practical monitoring layer for teams that want a clear next step.

Frequently asked questions
How often can checks run?
The available interval depends on the setup you request during early access.
Will one failed request wake me up?
No. Sentinel waits for two failed checks before sending an outage alert, so one network blip does not create unnecessary noise.
Can I share the result?
Yes. You can publish a public status page for the services you choose to show.
