Once the Search Service application has been created and when we go to the Search Administration page, if everything went well, we should see tick mark against the installed search components. However there can be instances where we come across the error “Unable to retrieve topology component health states. This may be because the admin component is not up and running”.

There are multiple reasons that can cause this issue. One of the reasons for this, is an issue with the ‘Usage and Health data collection’ service application. Ensure that the service application is created from the service applications page.

If it is not created, launch the Configuration Wizard.
![]()
Select the ‘Usage and Health data collection’ check box so as to create the service application.

Now in some cases the Usage service application will be created but might be in stopped state. In order to get it running, run the below Power Shell script.
- $Usage = Get-SPServiceApplicationProxy | where {$_.TypeName -like "Usage*"}
-
- $Usage.Provision()
![]()
Heading over to the Search Administration page we can now see the entire Search Topology in successfully created state.
