What is a check?

A check is the part of My Pingdom that is monitoring your URL, some might call it a monitor. It contains settings related to how you want it monitored and notified. Some of these settings include a name, a URL, an Alert Policy and an interval of how often the check tests your site for availability.

There's no limit on how many times we will test it, just how many URLs you can set up to monitor. Well, there is a limit per se, as the smallest interval is once a minute, this comes to 525600 requests a year per check.
