Checks your metrics every minute against a set of criteria. False alarm prevention built-in. Notifies you before failures can even happen.
Take full control of your alarms by setting the number of consecutive points until triggered as well as the number of clear points until it can be reset.
Logically combine multiple monitors under a single alarm, with the option of allowing multiple alerts per active alarm, thus allowing greater maintainability of alarms.
Be alerted of any issues by email, SMS or through your favourite application via webhook, e.g. slack.
