Alert processing

Below is an example of processing an event that is raised to alert in CrystalBridge® Monitoring:

_{Process of event occurrence}

During the process of event occurrence (X-axis: Value and Y-axis: Duration), the KPI line starts below the threshold but then begins to rise and crosses the threshold. This is when the process of detecting alerts starts:

When the KPI value reaches and crosses the threshold, the progress turns "Grey", which indicates the KPI value still has a chance to return under the threshold for up to a certain time-frame and the Duration has started for an event in CrystalBridge® Monitoring.
Since the KPI has remained above the threshold for the allocated time, the progress turns "Red", an event is started and the alert is raised.
The event continues even if the KPI value falls below the threshold "Grey area" because the progress needs to remain below the threshold for a certain period. If the progress stays below the threshold long enough, then the duration would stop. However, for this example, the progress again rises above the threshold and so the event continues.
As the event duration continues and an event period has elapsed, the system re-raises the alert to inform you the event is still occurring.
During the elapse of the second event period, another (third) alert could be raised depending on how you configured the event. This is because, this time the progress has dropped below the threshold, but the progress is grey since the progress has not remained below the threshold for a certain time frame.
Once the line has remained below the threshold long enough, the progress changes to green, and the event duration is finished. The system raises a green alert and informs you the event has ended.

Examples of e-mail alerts

After you set up the alert notification as an email, you may receive a similar message as below. CrystalBridge® Monitoring can send in one email more alerts at a time. The subject line shows the date and time of the first alert occurrence and the body of the email displays the number and the type of the alert, which occurred on a particular system.

Following notification types may occur:

This figure shows an error type alert.

This figure shows a success-type alert.

This figure shows a warning-type alert.

This figure shows an issue-type alert.

This figure shows an info-type alert that is sent when an alert is closed.
