The View Filters pane on the left side of the StackState UI allows you to filter the components (topology), events and traces displayed in each perspective. Applied filters can be saved as a view to open directly in the future.
Topology filters can be used to select a sub-set of topology components to be shown in any one of the available perspectives. You can browse your topology using basic filters or build an advanced topology filter that zooms in on a specific area of your topology using the StackState in-built query language (STQL).

The main way of filtering the topology is by using the basic filters. When you set a filter, the open perspective will update to show only the visualization or data for the subset of your topology that matches the filter. Setting multiple filters will narrow down your search further. You can set more than one value for each filter to expand your search
The example below uses basic filters to return components that match the following conditions:
- In the Domain
- AND has a Health state of
- OR is the Component with the name
The example below uses an advanced filter to return components that match the following conditions:
- In the domain
- AND has a health state of
- OR has the name
Filtering (advanced filter)
To optimize performance, a configurable limit is placed on the amount of elements that can be loaded to produce a topology visualization. The filtering limit has a default value of 10000 elements, this can be manually configured in
etc/application_stackstate.confusing the parameter
Note that the filtering limit is applied to the total amount of elements that need to be loaded and not the amount of elements that will be displayed.
In the example below, we first LOAD all neighbors of every component in our topology and then SHOW only the ones that belong to the
applicationslayer. This would likely fail with a filtering limit error, as it requires all components to be loaded.
withNeighborsOf(direction = "both", components = (name = "*"), levels = "15")
AND layer = "applications"
To successfully produce this topology visualization, we would need to either re-write the query to keep the number of components loaded below the configured filtering limit, or increase the filtering limit.
The View Filters pane on the left side of the StackState UI can be used to filter the events shown in the Events Perspective and in the Event list in the View Details pane on the right of the StackState UI.
The following event filters are available:
- Span types
- Span tags
For example, if you filter the trace list for all spans of type
database, this will return all traces that have at least one span whose type is
To update the existing view with the currently applied filters, click Save view at the top of the screen. To save the current filters as a new view, click Save view as. Read more about StackState views.
To clear any filters you have added and return to the saved view filters or initial clean state, click on the view name at the top of the screen. Alternatively, you can select Reset view from the Save view dropdown menu at the top of the screen, or Reset from the ... menu in the View details pane on the right of the screen.
