The topology in StackState is likely much bigger than what you care about at any given time. StackState allows you to filter the topology to locate the part of the topology you are interested in.
The main way of filtering the topology is by using the basic filter panel, accessed using the filter icon.
When you open StackState’s topology view initially, it will show you all of the topology it can, provided it doesn’t go over the configured topology limit. If there is more topology than can be shown while still keeping the system usable, StackState shows you a warning message and suggest you apply more filters to your topology selection.
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
Using the basic filter panel you can select a subset of your topology based on the following properties:
In addition to specifying which components to show, the basic filter panel also allows you to specify two settings.
Root Cause Analysis automatically expands the topology selection to display the root cause of an issue. There are three settings:
Show Components adds one or more specific components to the topology selection. You can search for the component by name.
Here is an example of using the basic filtering capabilities. This example shows how to filter for a particular layer (
Applications) and a tag (
The same topology selection can also be shown in list format:
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.
Show expands the topology selection in one of the following ways:
Show only with … isolates the selected component (shows only that component) and expands the topology selection in one of the following ways:
