Error conditions overview

Error conditions play a major role in generating your monitor alerts. Setting up an error condition is the first step of the alert and error flow cycle that lets you receive alert messages.

An Error condition lets you define a set of criteria to inform your monitor of any errors on your website, web service, or server. It serves as your monitor’s basis for deciding which website behaviors result in an error and which don’t.

If, for example, you want to ensure that your website takes less than three seconds to load, you can set an error condition and specify thresholds for the page load time. Similarly, if you want to check if your website’s contents, plugins, or scripts load correctly, you can set specific error conditions for each.

Once any error condition is met, an error is generated, triggering an alert. If alerting is configured, you’ll be notified by an alert message right away.
