Where Exometer starts
Uptime monitoring that doesn’t cry wolf.
Exometer checks your websites and APIs from cities around the world. A single failure is a rumour: it counts only after a second location confirms it, so the alert you get is about a real outage, not a bad network path.

What happens when a check fails
- A check fails in Frankfurt. HTTP 503, or a timeout, a refused connection, a bad certificate.
- Another location tries at once. London, or wherever is online, in a different region when it can.
- Both failed: the outage is confirmed. If the retry passes, the failure is kept as unconfirmed and nobody is paged.
- Your alert policy sends it. Right away or after a delay you choose, with reminders while it stays down.
- It answers again. The outage closes and the same people hear that it recovered, and for how long it was down.
One page per check, with the evidence
Open a check and the record is all there, measured from each location rather than averaged into one number you can’t question.
- 90 days
- Daily uptime and every outage, with how long it lasted and why.
- Where the time goes
- Each response split into DNS, connect, TLS, first byte and download.
- Every location
- The latest result from each city, so a regional problem looks regional.
- Expiry
- Certificate and domain registration dates, with a warning days ahead.
- Alerts sent
- Who was told, on which channel, and whether it was delivered.

Alerts where your team already is
Email, SMS and WhatsApp, Slack with one click, Microsoft Teams, Discord, Google Chat, Telegram, and signed webhooks for everything else.
- Confirmed first. Phone numbers and addresses get a code before they receive anything.
- Alert policies. Group channels as “Production on-call” or “Web team” and change who’s paged in one place; new checks start with your default.
- Down, still down, back up. Recovery messages go to whoever got the alert, and certificate or domain expiry warnings go out before they bite.

Checks that test what matters
A health endpoint is a start. Exometer can call the API the way your clients do.
- Requests
- GET, HEAD, POST, PUT, PATCH, DELETE or OPTIONS, with your headers and a JSON, form or text body.
- Credentials
- Basic auth or a bearer token, stored encrypted and never shown again.
- What counts as up
- Any mix of 2xx, 3xx, 4xx and 5xx, or exact codes such as 204 or 418; redirects followed or not.
- How often
- Every 15 seconds to every 24 hours, with a timeout you set.
- From where
- Every location, chosen regions, or specific cities.
- Network
- IPv4 or IPv6, either first with the other as fallback, or one only; certificate verification on or off.
