What can trigger an alert?

Let us first differentiate between measured value alerts and service alerts:

• Measured value alerts are alerts related to measured values. The target group for these alerts are users involved in the analysis of the data.

• Service alerts are alerts related to the devices or data sources that deliver the measured values. The target group for these alerts are service technicians that take care of the measurement hardware or the measurement.

For measured value alerts, there are different triggers for which there is a separate type of alert definition:

• Measured value alerting
  There are two options here:

  1. An alert is triggered if a measured value in a channel has exceeded or fallen below a threshold value set in the alert definition.

  2. An alert is triggered if the device or the data source has detected an alert. The measurement data is then not examined further in Sedrix and an alert is directly created.

• Vibration event alerting
  An alert is triggered if a vibration event has exceeded a certain threshold value relative to a selected standard. The threshold values are given here as a percentage.

• Document alerting
  Alerts are triggered manually here, not automatically.

There are the following types of service alerts:

• Online status alerting
  An alert is triggered if a device or data source sends no data for a certain amount of time.

• Log notification alerting
  An alert is triggered if a certain message occurs in the log of a device. Rules are defined in the alert definition for this purpose.

• Error code alerting
  An alert is triggered if a measured value in a channel has a certain error code.
