Events

When a device is selected in the Performance Analysis > Condition Monitoring menu, the Events tab is available. This tab shows all events created by rules or machines, helping users quickly find and understand potential problems. The AI feature "Event Sequence Detection" looks at connections between events to help spot issues early.

The following display options are available:

The List tab displays events in a list and trigger event sequence detections
The Grouped List tab Display events in a grouped list and count the number of occurrences of each event.
The Chart tab view the events in a chart, based on the timeline. It is possible to zoom in and out of the chart and navigate through time.
The Event sequences tab displays calculated event sequences of the AI Service.

List tab

Machine messages, technical information and rule events of the device are displayed in a table in the detailed view under the Events tab in the List sub-tab. By default, the results of the last 24 hours are displayed. Here its also possible to trigger event sequence detection.

Event Sequence Detection details

If the Backend-Service AI Services module is installed, event sequence detection is available.

When using event sequence detection to find a specific event target, the event sequence detection analyzes event data, such as rule results and machine messages. Event sequence detection can be used to detect anomalies before an event target is reached.

A rule can be created for event sequence detection. A rule is triggered as soon as the specified sequence occurs. In this way, certain behaviors can be identified so that they can be responded to as quickly as possible.

The event sequence detection calculates the following variables:

Confidence

Confidence indicates how often the event target occurs after the sequence.
support

Support indicates how often the sequence occurs before the event target.
Relevance

Relevance is the geometric mean value of Confidence and Support.

Prerequisites

Production planner or Administrator role
The Backend-Service AI Services module has been installed.
At least two event targets have occurred during the specified time period.

Example calculations

Performance size	Description	Calculation
Confidence	In 6 (= dark red A or C) out of 9 (= dark red A or C) cases, the event target (= T) occurs after the sequence. Values in the event sequence details: Event Sequence Details Target event and sequence/number of (viewed) target events = confidence value
support	In 6 (= dark red A or C) out of 8 (= T) cases, the sequence occurs before the event target (= T). Values in the event sequence details: Event Sequence Details Target event and sequence/(target event and sequence + sequence without target event) = support value
Relevance	The relevance indicates how well event sequence detection leads to the target event. Values in the event sequence details: Event Sequence Details √ (confidence value + support value) = relevance value
