Unhealthy components in a view are grouped into based on how they're connected in the topology. When StackState identifies a problem, this will be reported in the right panel under Problems.
The View summary and Subview summary tabs list all problems that impact components in the current view or subview.
The Component details tab lists all problems that involve the selected component.
The Direct relation details tab lists all problems that involve the selected direct relation, its source component or its target component.
You will find the most recently updated problem at the top of the list and the problem with the oldest update at the bottom. Whenever a problem is created or updated, it will move to the top of the list. Within each problem, the involved components are listed in order of the timestamp of their last health state change, from the most recent at the top to the oldest at the bottom.

Select a problem to open detailed information about it in the right panel details tab - Problem details.
The Problem details tab gathers together all the information you need to get started investigating a problem in your landscape:
Select a Metric stream anomaly event in the Events Perspective.
Detailed information about the event is displayed in the right panel details tab - Event details.
The affected stream is displayed highlighting the detected anomaly.
Element properties changed events are generated whenever relevant properties of a component are updated at the synchronization source. For example, if AWS security rules are changed or a load balancer has increased its capacity. Exact details of the change are provided.
Select an Element properties changed event in the Events Perspective.
Detailed information about the event is displayed in the right panel details tab - Event details.
Click Show all changes in the right panel details tab.
A diff of the old and new properties is displayed.
Version changed events are generated whenever the version property of a component is updated.
Root cause - Each problem has a single root cause. This is the unhealthy component at the bottom of the dependency chain.
Contributing cause - A problem can contain any number of contributing causes. These are all of the unhealthy components in the problem, other than the root cause.
Healthy components - A number of healthy components are also included in a problem:
Upstream healthy dependencies of the root cause or one of the contributing causes.
Within a problem subview, you have access to all perspectives containing data specific to the problem time window and the involved components. The applied filters can be adjusted, but it isn't possible to save the subview. You can share the problem subview with other StackState users, including any modifications you have made, as a link.
To exit the Problem Subview, click the view name in the top bar of the StackState UI.
All in the problem (the root cause and contributing causes).
The of unhealthy components - events that may have triggered the unhealthy state changes in the problem.
Click INVESTIGATE IN SUBVIEW to open all components in a problem in a dedicated, temporary .
For each reported problem, StackState will list all events that are likely to have contributed to unhealthy state changes in the problem. These could be events of type Anomaly, Element properties changed or Version changed that occurred within the and relate to components in the problem. If no relevant probable cause events are available in StackState, the list will be empty.
Anomaly events are generated whenever an anomaly is detected by the . For metric stream anomalies, details of the metric stream where the anomaly was found are provided.
Click on the metric stream graph or select inspect from its menu (...) to open the and inspect the stream in more detail.
A problem subview is a temporary StackState view. The filters applied to a problem subview return all components related to the problem root cause and any contributing causes within the . This is a larger set of components than would be shown by selecting to show the . The following components will be included:
Downstream healthy components with an unhealthy that originates from either the root cause or one of the contributing causes.
