Website Data Alerting for LM Uptime

LogicMonitor raises alerts on websites using LM Uptime when a specified number of checks fail at one or more locations. These alert conditions are configured individually for each website during the setup or management of a Web Check or Ping Check. The way alerts are triggered depends on the type of check and whether it originates from an external checkpoint or an internal  LM Collector. For more information on the setup, see Web Check Overview using LM Uptime or Ping Check Overview using LM Uptime.

Alert messages for websites can be customized globally using templates. There are two template types available, one for individual location failures (Website Alert) and one for aggregated multi-location failures (Website Overall Alert). These messages support tokens to include dynamic, relevant information for more effective alerting. For more information, see Managing Alert Message Template.

Website alerts for LM Uptime can be viewed on the main Alerts page, which shows all active alerts across LogicMonitor, or in the Alerts tab of a specific Website Check or group. The Alerts tab offers a filtered view tailored to the selected website and functions. For more information, see, Alerts Tab and Managing Alerts from the Alerts Page. 

Website Alert Calculation

The time required to trigger an alert is based on the following formula:

(Number of failed checks – 1) × Check interval = Time to trigger an alert

For example, if alerts are set to trigger after 7 failed checks at a 10-minute interval, the alert is raised after 60 minutes of continuous failure. Alerts clear only after the checks pass continuously for the same duration.
