Check for entries of the following form to ensure that the Coordinator is successfully initiating Cube data processing:

INFO PokeCubeProcessing - Sending cube processing request to https://TACHYON.Acme.local:443/Experience/
INFO PokeCubeProcessing - Sent cube processing request successfully

Ensure no errors are reported in the Coordinator log.

If the log reports connection error messages such as the following, then ensure SQL Server Analysis Services (MSSQLSERVER) is running. If not restart it.

ERROR [INV02\Administrator] Tachyon.Server.Common.Http.WebApiExtensions.ApiControllerBase - Invalid request.

If an error occurred is displayed please run the browser developer tools to analyze the Tachyon API calls used to populate this page. If for example, you see authorization errors then please check the SQL user permissions of the Cube using SQL Management Studio. If you see connection errors, check the SQL Service Analysis Service is running.

Check that Cube data has been processed by examining the properties of the TachyonExperience cube:

Ensure TachyonExperience tables Event, DevicePerformance, SoftwarePerformance etc. have been populated. For example, under SQL Management Studio run the following query on the Tachyon Experience database:

select t.Name, e.Data, t.Description from [Event] as e inner join [Topic] as t on t.Hash = e.TopicHash order by t.Name

If no Experience data is present or some missing data, then ensure that the data has been sent from the 1E Client to the Switch by examining %programdata%\1E\Client\1E.Client.log and ensuring that updates have been sent daily from the Agent to the Switch, such as:

[51384] INFO - Generating performance summary events for 2020-01-08T00:00:00.000Z
[51384] INFO - Published 1 device performance and 122 software performance summary events for 2020-01-08T00:00:00.000Z
[45296] INFO - 123 events pending for Switch transmission
[45296] INFO - Withholding 118 event(s) for subsequent Switch payloads
[45296] INFO - Sent 5 events(s) to Switch
[45296] INFO - Storing an additional 118 pending event(s) for subsequent payloads to Switch
[45296] INFO - 118 event(s) pending for subsequent payloads to Switch

If you don't see these kinds of Agent INFO log messages then ensure a policy has been sent to the Agent from the Switch, remember that you have to deploy the Event Subscriptions to the Agents by using the Deploy button in Guaranteed State even if you have no policies (you want) to deploy:

This will generate a policy document containing the event subscription data under %ProgramData%\1E\Tachyon\PolicyDocuments for deployment to devices:

{"Rules":[],"EventSubscriptions":[{"Topic":"Device.Performance"},{"Topic":"Software.Performance"},
{"Topic":"Device.PerformanceAnomaly"},{"Topic":"Patch.Install"},{"Topic":"Patch.Uninstall"},
{"Topic":"Software.Crash"},{"Topic":"Software.Hang"},{"Topic":"Software.Install"},
{"Topic":"Software.Uninstall"},{"Topic":"Software.PerformanceAnomaly"},
{"Topic":"Operatingsystem.Boot"},{"Topic":"OperatingSystem.Crash"},
{"Topic":"OperatingSystem.PerformanceAnomaly"},{"Topic":"OperatingSystem.ServiceFailure"},
