Alert types

There are three types of alerts you can track with Logmore Cloud

  1. Single measurement
  2. Cumulative time
  3. Mission duration

1. Single measurement

Single measurement alert type is good for basic alerts. Alert is generated if any of the measurements made by the QR logger is violating the alert rule.

Alert delay

Alert Delay can be set for Single measurement alerts to allow several consecutive measurements which violate the alert rule limit before generating the alert.

By setting a delay to the alert rule, you allow the alert to be triggered only after that many unacceptable measurements have been logged. The delay value N + 1 (measurement) is when the alert is generated

Examples:

  • Delay value 0 = All measurements outside the set parameters will trigger an alert
  • Delay value 1 = Alert at the 2nd consecutive measurement outside the set parameters
  • Delay value 3 = Alert at the 4th consecutive measurement outside the set parameters

The actual timeframe depends on both the delay setting and the measurement interval. For example, with a 2 measurement delay (delay value 2), the third time a measurement is consecutively outside the set parameters, an alert is generated. With a 10 minute interval, that means that the parameters have been broken continuously for 30 minutes.

2. Cumulative time

Cumulative time alert type tracks the total time the rule is violated during the mission. In some cases, temperature (or any other parameter) variance is OK as long as it doesn't exceed a specific total time. You may want to use this alert rule for instance for shipments that change hands between different carriers often to make sure the product doesn't unfreeze while moving between freezers.

3. Mission duration

You can set an alert to trigger if a mission has lasted for longer than a set time. You might want to use this setting for instance for temperature-sensitive shipments that are transported without temperature-controlled containers, and know that they remain usable for a certain time despite the temperature variance.

Combined with the possibility to end missions automatically on scan, this alert type can provide critical information if loggers go unscanned for too long.
