Topology Perspective
StackState Self-hosted v4.6.x
This page describes StackState version 4.6.
The Topology Perspective displays the components in your IT landscape and their relationships.
Topology Perspective
The Topology Perspective shows the filtered components and relations in a selected view or the entire, unfiltered topology in explore mode. Components that have one or more health checks configured will report a calculated health state.
When you hover over a component, the component context menu is displayed. This gives you information about the component, including its name, type, health state and propagated health state and the top metrics. You can also run shortcuts and the actions specific to the component from here.
Component context menu
Actions can be used to expand the topology selection to show all dependencies for the selected component. Other actions may be available for specific components, such as component actions that are installed as part of a StackPack.
A list of the available actions is included in the Component Details pane when you select a component and also in the component context menu, which is displayed when you hover over a component.
Actions
Shortcuts give you direct access to detailed information about the specific component:
- Show properties - Opens the properties popup for the component. This is the same as clicking SHOW ALL PROPERTIES in the Component Details pane.
- Investigate in subview - Opens a subview containing only this component. The subview allows you to investigate a single component in all perspectives without needing to adjust the view filters. This is the same as clicking INVESTIGATE IN SUBVIEW in the Component Details pane.
Relations show how components in the topology are connected together. They are represented by a dashed or solid line and have an arrowhead showing the direction of dependency between the components they link. Health state will propagate from one component to the next, from dependencies to dependent components. Relations that have one or more health checks configured will report a calculated health state.
Click on a relation to open the relation details in the right-hand pane.
Indirect relation path
The components and events displayed in the topology visualization can be customized by adding filters.
Click the View Filters icon in the left-hand side menu to open the view filters. Here you can edit:
- Topology filters: The components displayed in the topology visualization.
- Events filters: The events shown in the Events list in the View Details pane on the right-hand side of the screen.
From the Component Details pane, click on a label to add this to the topology filter. The displayed topology will be expanded to include all components and relations with the selected label. To undo a label selection, click the back button in the browser or edit the topology filter in the view filters.
The visualization of components and relations in the topology perspective can be customized in the visualization settings. Click the Visualization Settings icon in the left-hand side menu to open the visualization settings menu. Here you can edit:
- Root cause display - to what extent the view should be expanded when an element in the view reports a DEVIATING or CRITICAL health state or propagated health state.
- Grouping - should all components be displayed individually or should like components be grouped. For details, see component grouping.
- Indirect relations - should relations between components be shown if these connect through other components that are not displayed in the view. For details, see relations.
The Visualization Settings are saved together with the View. For details, see the page Visualization settings.
If one or more components in a view have a critical state, StackState will show the related components and their states as a Problem in the View Details pane.
There are zoom buttons located in the bottom right corner of the topology visualizer. The plus button zooms in on the topology, the minus button zooms out. In between both buttons is the fit to screen button which zooms out so the complete topology becomes visible.
You can locate a specific component in the topology by clicking
CTRL + SHIFT + F and typing the first few letters of the component name. Alternatively, you can select the Find component magnifying glass icon in the bottom right corner of the topology visualizer.If there are components with telemetry streams and health checks in your view, the Topology Perspective will calculate a health state and propagate this state throughout the graph. The propagated health state will help you to see the risk of affecting other components.
It is possible that your view can contain components that have a deviating propagated health state caused by a component that is outside your view. The Topology Perspective allows you to configure whether the view should be expanded to show root cause components that are outside of the currently displayed view:
- Don't show root cause - Do not show the root causes of components shown by the current topology filters.
- Show root cause only - Only show the root causes of components shown by the current topology filters that have a
CRITICALorDEVIATINGpropagated health. Indirect relations are visualized if a component directly depends on at least one invisible component that leads to the root cause. - Show full root cause tree - Show all paths from components shown by the current topology filters that have a
CRITICALorDEVIATINGpropagated health to their root causes.
Root cause
The components in the topology visualization can also be shown in a list instead of a graph:
Filtering(list format)
From list mode, the component list can be exported as a CSV file. The CSV file includes
name, state, type and updated details for each component in the view.- 1.From the topology perspective, click the List mode icon on the top right of the screen to open the topology in list mode.
- 2.Click Download as CSV from the top of the page.
- The component list will be downloaded as a CSV file named
<view_name>.csv.
