count with and without filter

[PowerBeeEye]

I am working with the data below - table of organizations, servernames and services installed on each server:

Query_Server_Services

Company	forest	SystemName	ServiceName
Contoso	contoso.com	ContosoSrv1	svc1
Contoso	contoso.com	ContosoSrv1	svc2
Litware	litware.net	LitwareSrv1	svc1
Litware	Litware.ca	LitwareSrv1	svc2
Fabrikam	fabrikam.org	Fabrikamsrv1	svc1
Fabrikam	fabrikam.org	Fabrikamsrv2	svc2

I have slicers for company name, forest name and service name.

If I filter for company, forest and service, how can I get the number of servers in that company and forest WITHOUT that service?

I have been able to plot the number of servers WITH the service using 

= CALCULATE (DISTINCTCOUNT(Query_Server_Services[SystemName]))

Any help is appreciated!

For your count with service you don't need the calculate.

Count with service = DISTINCTCOUNT ( 'Table'[SystemName] )

Then we can use that one and some filtering to calculate those without the selected service.

Count without service = 
CALCULATE(
    DISTINCTCOUNT('Table'[SystemName]),ALLEXCEPT('Table','Table'[Company],'Table'[forest])) - [Count with service]

This counts the total number of systems for the selected [Company] and [Forest] using any service the subtracts the count for the selected service leaving us with the number not using the service.

My sample file is attached for you to look at.

Quick question - how can I get a list of servers NOT running a service (SVC2, for example).

Since there are no rows indicating that SVR2 is NOT running SVC2, I understand this is not possible by default.

But would be possible to find "find all servers running SVC1 (assuming it runs on all servers) but NOT SVC2 (selected using the slicer)?

Thanks!

That was an interesting one.  This should get you what you are looking for.

Systems without service = 
VAR _Systems = VALUES ( 'Table'[SystemName] )
VAR _AllSystems = ALL ( 'Table'[SystemName] )
VAR _Missing = EXCEPT(_AllSystems,_Systems)
RETURN 
CALCULATE ( 
    CONCATENATEX ( 
        VALUES ('Table'[SystemName]), 'Table'[SystemName],", " ),
        ALL ( 'Table'[ServiceName] ),
        'Table'[SystemName] IN ( _Missing ) 
)

@jdbuchanan71thank you very much; again this has been incredib;y helpful!

@PowerBeeEye  it might work

Measure = CALCULATE(COUNTROWS('Table'), ALL('Table'[ServiceName]))
