Let’s get technical (if you’re into that)

You don’t need to be computer savvy to set up our tool. But if you are, we’re happy to explain exactly how it works and how you can customize Oh Dear to your specific needs.

world map

Multi-location monitoring

to prevent false alerts

Each site is monitored from a primary location and verified from a secondary location. You can choose your primary location from within the Oh Dear dashboard.

If the primary location reports an error to Oh Dear, the secondary location is used to verify the problem. We'll only trigger an alert if both the primary and the secondary checks report the site as down. This prevents any false alerts.

200 http response

HTTP/200 response

within a reasonable timeframe

If we fail to receive an HTTP/200 response within a reasonable timeframe, we mark your site as down. When we see website failures for 2 minutes in a row, we send out notifications so you can intervene. This prevents monitoring flaps and false positives.

You can change the timing threshold in your settings. Prefer to get alerted after 5 minutes instead of 2? Not a problem. Our downtime reports give you all the details to quickly verify and troubleshoot any alert.

In our report you'll find useful commands to replicate our monitoring, this allows to you see exactly what we see.

content verification

Content verification

& checkstring monitoring

Is just monitoring a status code not enough? We can verify the existence of a piece of text on the page too (a so called "checkstring"). If we receive an HTTP/200, but the checkstring is missing in the source code, we'll mark the site as down.

select http verb

Monitoring beyond a GET request

Verify submissions, monitor search results,…

By default we monitor using a GET HTTP call, but you can also change this to POST, PUT or PATCH.

Each method can have its own form payload. This allows you to simulate a form submission and monitor search results, contact forms, API endpoints, ...

You could even perform a website login through a POST call and verify the account page loads properly.
