Using the KairosDB UI

You can use the KairosDB UI to query the data store and graphically view stub metrics for virtual services across IBM® Rational® Test Virtualization Server and IBM Rational Integration Tester as reported to IBM Rational Test Control Panel.

You must install the KairosDB in the same system that is running Rational Test Control Panel.

You can access the KairosDB UI only from browsers local to the system running the Rational Test Control Panel.

  • Task flow in using the KairosDB UI
    You can perform tasks in sequence to use the KairosDB UI to query the data store and graphically view stub metrics for virtual services.
  • Launching the KairosDB UI
    To view the query and the graph of the metrics for the stubs running on Rational Test Control Panel, you must launch the KairosDB UI.
  • Selecting a time range and the time zone
    You must first select the time range during which the KairosDB collected the metrics for the stubs. The time would correspond to the time when the stubs ran on Rational Test Control Panel.
  • Selecting metrics
    You must select metrics for the stubs you ran to include them in the KairosDB query.
  • Grouping metrics
    You can group the data points collected for the metrics in the database into groups and assign aggregators to the grouped data so that the data values can be presented in a simplified graph.
  • Assigning aggregators
    After you group the data points, you can assign aggregators to the grouped data points so that the selected operation is performed on the data points. For example, you can count the number of data points that exist in a 10-minute time period.
  • Assigning tags
    You can use Tags in your query for the selected metric so that the result displays the data points with the selected tags and their values specified.
  • Viewing the graph
    You can view the graph for the query you created using the KairosDB UI. You can view the graph at any stage of the query you are creating.
  • Using the link to the graph
    You can create a link to the graph for your query by using the KairosDB UI so that others can use the link to view the graph.
  • Viewing and saving the query
    After you create your query by using the KairosDB UI, you can view the query and save it to the local folder that you can use later to reload the query in the KairosDB UI.
  • Using the saved JSON request
    You can use the saved JSON query with an HTTP POST or HTTP GET to retrieve the raw data points and their values from the KairosDB data store.
