This page describes StackState version 4.6.
Overview
Telemetry streams in the right-hand component pane of the StackState UI are displayed in order of telemetry stream priority. There are four levels of priority: High, Medium, Low, and None. By default, all streams have priority set to none.
Stream priority is used in StackState to help determine the following:
The order in which streams are displayed in the Telemetry list in the component and relation details pane on the right-hand side of the StackState UI. Streams are ordered by priority (highest at the top) and then alphabetically.
The streams that are shown as Top metrics in the component context menu - this is the pop-up displayed when you hover the mouse pointer over a component in the Topology Perspective. The most recent metric received from the first three streams in the Telemetry list will be displayed.
The order in which streams are displayed in the Metrics Perspective.
Set the telemetry stream priority
To change the priority of a specific stream, follow the instructions below.
1. Open the Component Details pane
Locate the component that you want to edit Telemetry streams for. Click on the component to open the Component Details pane on the right of the screen - see the screenshot below:
This displays the details of the component, such as Properties, Health status, and Telemetry.
2. Choose the telemetry streams to prioritize
Components can have multiple Telemetry streams. They are presented in a column, so not all of them are visible at first. Let's say that instead of BytesReceivedRate, you want to see PacketsReceivedRate right after the basic_health stream. Click on the triple dots menu in the top-right corner of the basic_health stream and choose Edit:
3. Set stream priority
In the basic_health stream edit screen, set the Priority field to High, as this stream should be presented at the top of the list. Click Save and confirm the change:
Now navigate to the PacketsReceivedRate stream and open the stream editing screen. Set the Priority field here to Medium:
All streams have their priority set to None by default, so the PacketsReceivedRate stream is presented above them and below the basic_health stream, which has its priority set to High.
