Workaround the issue by upgrading to Splunk version 7.2.x and above.
Despite Splunk 8.03 and Splunk App for Infrastructure 2.1.0, I also have this no result panels (whereas the data is ok in analysis panel).
Is it because the requests search for "cpu.*" ? How can I adapt this to windows (and linux) machines ?
Do you have "meta = **entitytype::Windows_Host**" in UF Perfmon inputs.conf stanza?
