Investigating events
To open the Active Events screen, select Active Events from the Events menu.
Based on your historical data, the product builds models that reflect what normal is in your environment. The realtime or playback data is compared against these models and a Z-Score is calculated for each KPI Group. The Z-Score provides a distance measure of how far a raw value is from its modeled mean in terms of standard deviation units. A High deviation reflects a standard deviation that is twice as large as the Low deviation.
For example, if we define the low deviation limit as ±1.5 standard deviations from the mean, and the high deviation limit as ±3.0 standard deviations from the mean, then the Low deviation state range is between 1.5 and 3 standard deviations from the mean and the High deviation state range is more than 3 standard deviations from the mean. The model sensitivity dictates the normal range and the ranges of the levels of deviation.
You can change the sensitivity of the product so the score needs to have a higher variance from the Z-Score to change the state. For more information, see Setting-the-global-sensitivity-level.
If BMC AMI Ops Insight has not detected any anomalies, a summary of the monitored KPIs and KPI groups is displayed.
A summary of the events is displayed at the top of the page:
A tile is displayed for each Db2 Data Sharing Group, Db2 subsystem, and LPAR that is in an anomaly state, as follows:

6 | Classification of the event |
7 | Drill-down hyperlink to investigate an event |
To view events by LPAR or Db2 Data Sharing Group
Click Group by, and select LPAR or Db2 Data Sharing Group.
The tiles are grouped on the display by LPAR or Db2 Data Sharing Group according to your selection.
To filter specific events, click Filter, check the events you want to view, and then click Apply.
To investigate an event
To investigate an event, click Investigate in the tile of the event you want to investigate.
The following tabs are available:
- Probable Cause Analysis—Information that helps you identify the source of the event
- Event Progression—Details of the event over time
In the Probable Cause Analysis and the Event Progression tabs, when you click
, the following options are displayed:
Probable Cause Analysis
The Probable Cause Analysis tab displays the current most probable sources (classifications) of the anomaly based on the current data. It provides a graphical representation of the current impacted KPI Groups and the connections between them on the most critical paths. Any change in the classification during the running of an event is indicated by 
.
You can expand the WLM importance total group by clicking any node to display all the available WLM importance group in that node. The Event Classification section has a filter option to view a subset of information in the classification graph.
Below the graphical representation, the affected KPI Groups are listed with more details.
Graphical representation of affected KPI Groups
The tab contains a graphical representation of the affected KPI Groups and includes the following sections:
Item | Section |
|---|---|
1 | |
2 | |
3 | |
4 | |
5 | |
6 | |
7 | |

The graphical representation displays an icon for each KPI Group that is defined in the application. Each icon indicates the category the KPI Group belongs to. For details, click Legend (
) on the right of the screen. The KPI Groups are connected by arrows that indicate how they influence each other. These arrows are then included in the paths that are identified to be most likely sources of the problem, (classifications).
The icons are color coded as follows:
Color | Description |
|---|---|
Red | Classification This indicates that the KPI Group has been identified as a source of the current anomaly. |
Orange | High deviation from normal |
Amber | Low deviation from normal |
Grey | Normal |
Limit breaches are indicated in the graphical representation by a red dot orbiting around the affected KPI Group.
1. Event Timeline
Above the graphical representation is a timeline of the event. You can select a specific point on the timeline to see the state of things at that time. All other areas of the tab are affected by the timeline. Use the arrows (< or >) to jump forward on the timeline or click Event Start or Latest Ingested to go to the beginning of the event or the latest data.
2. Limit Breaches
Limit breaches are listed on the left, above anomaly classifications.
In some cases, The breached KPI Group is also the source of the problem. If that happens the KPI Group appears in red with the orbiting dot, and no Limit Breach Path is available.
