Topology Perspective
See the architecture of your IT landscape.
This page describes StackState version 4.0.
The StackState 4.0 version range is End of Life (EOL) and no longer supported. We encourage customers still running the 4.0 version range to upgrade to a more recent release.
The Topology Perspective displays the components in your IT landscape and their relationships.
Components and relations
The Topology Perspective shows components and relations in the selected view. Components that have one or more checks configured will have a calculated health state.
Component details
When a component is selected by clicking on it, the Component Details panel is shown on the right hand side. This panel displays detailed information of the component:
metadata such as the component's name, type and labels
Filtering
By design, there is only one topology per StackState instance to make sure any part of the topology can always be connected to any other part. The topology is, of course, segmented in many different ways depending on your environment. You can narrow down on the part of the topology you are interested in filtering.
Using basic filtering
The main way of filtering the topology is by using the basic filter panel, accessed using the filter icon.
From here, you can use the basic filter panel to filter the topology on certain properties. If you select a particular property, the topology view will be updated to show only the topology that matches the selected value. Selecting multiple properties narrows down your search (ie, it combines them using an AND operator). Selecting multiple values for a single property expands your search (ie, it combines them using an OR operator).
Using the basic filter panel you can select a subset of your topology based on the following properties:
layers
domains
environments
types
health state
tags / labels
Layers, domains, and environments are a way to organize your topology. The health state reflects how the component is functioning. Use labels to make it easy to navigate your topology.
Filter settings
Show Components adds one or more specific components to the topology selection. You can search for the component by name.
Basic filtering example
Here is an example of using the basic filtering capabilities. This example shows how to filter for particular components and customers.
The same topology selection can also be shown in list format:
Interactive navigation
It is also possible to interactively navigate the topology. Right-click on a component to bring up the component navigation menu:
Selecting an action from the menu allows you to change your view, respective to the selected component.
Quick Actions expands the topology selection in one of the following ways:
Show all dependencies -- shows all dependencies for selected component
Show dependencies, 1 level, both directions -- limits displayed dependencies to one level from selcted compontent
Show Root Cause -- if the selected component is in a non-clear state, adds the root cause tree
Show Root Casue only -- limits displayed components to the root cause elements
Dependencies isolates the selected component (shows only that component) and expands the topology selection in one of the following ways:
Direction -- choose between Both, Up, and Down
Depth -- choose between All, 1 level, and 2 levels
If you require more flexibility in selecting topology, check out our guide to Advanced topology querying with STQL.
Component finder
Locate a specific component in the view by typing the first few letters of it's name in the Topology Perspective. Alternatively, you can select the Component finder icon magnifying glass in the bottom right corner of the topology visualizer.
Zoom in, zoom out and Fit to Screen
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.
Problem clusters
If one or more components have a critical state, StackState will show the related components and their states as a Problem Cluster in the View Overview pane.
Root cause display
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. This means your view can contain components that have a deviating health state caused by a component that is outside your view.
The Topology Perspective allows you to configure whether to show the root cause if it is outside of your view:
Don't show root cause -- do not show the root cause
Show root cause only -- only show the root cause component
Show full root cause tree -- show the entire root cause tree
List mode
The components in the view can also be shown in a list instead of a graph.
