Changing Grid Settings

To review the Grid's settings, do the following:

How to

  1. To change the Locations, Test Server Instances, or ResultsService Instances, click the Back button once to display the Server Instances page for this grid. Grid settings can be changed either by adding or removing Locations, selecting a Composition(s), changing Result Server settings, or by changing Advanced Settings per Location.Note: Locations are created automatically whenever you configure a Cloud Provider Account for a given cloud vendor. You can review these in advance in the Central list > Locations.
  2. To add an additional Location to this Grid, click the Plus (+) icon in the existing section to add a second one.When you do so, the new location is added to the existing form at the bottom. Select from the drop-down in the new location area to specify a location other than the one shown.
  3. Specify the number of Test Server instances to be created per Location (you can skip this if these settings come from selecting a composition).
  4. Define Result Server instances per Location as a ratio to Test Server instances or as a Fixed Amount.TIP: Click Select Composition(s) to use the settings from one or more test compositions.
  5. Optionally, in the Server Instances page, check Show Advanced Settings (per Location) to perform any of the following tasks:
    • To specify server classes for Test Server or Results Service instances
    Configured Server Classes can be selected from the Server Class drop-down. See Server Classes.
    • To specify a zone in which servers will be launched
    With the default Zone Distribution > All in the Same Zone radio button checked, select a zone from the available zones in the drop-down. Optionally, check the Failover to different zone(s) if initial allocation fails box if you want CloudTest to use different zones on retry.
    • To switch from the default server allocation algorithm (which tries to allocate servers all in one zone and only when it cannot switch to another zone) to another algorithm that will get servers in groups of 25 doing round robin on all of the zones
    Check the Distribute evenly across all zones box to use the alternate round-robin algorithm for server instances.

  6. Click the Next button to return to Step 3: The Summary and Deploy/Tear Down page appears.
