Configure thresholds to get alerted when a monitor is Down

How to set thresholds and get alerted based on the number of DOWN locations?

By configuring the proper thresholds for your web application, you can decide when to get alerted for a DOWN monitor. Let's say you have a web application that you monitor from our three global locations and your downtime rule is set as three locations, by default. Based on the threshold configuration, alerts will be triggered only when all the three monitoring locations report an outage; not when anyone of these three locations (including the primary location) report an UP status.
However, if you still wish to get alerted even when a single monitoring location reports an outage, you must then change the Downtime Rules  " Number of locations to report monitor as down " in Threshold profiles to one location. This can be modified as per your need.

To access the threshold profile settings, follow the steps below:
  1. Log in to Site24x7.
  2. Navigate to Admin > Configuration Profiles > Threshold and Availability > Add Threshold Profile > Threshold Profile.
  3. In the pop-up that appears, under the Downtime Rules section, in the Number of locations to report monitor as down field, select the desired number of locations to report the monitor as DOWN.
  4. Click Save.
