Is there an easy well to find out the last time all the cubes on a server were processed? I've got over 20 cubes on one of our SSAS instances and would like to find out the last time the cubes were processed and also the last time the cubes were accessed. I know I can run the code below to look at one cube but I'm looking for a way to do it on all cubes.
SELECT LAST_DATA_UPDATE FROM $system.mdschema_cubes
Any help would be greatly appreciated!
Thanks,
Elizabeth

Would appear you'd need to create some outer loop (maybe using SSIS to do this?) -you can't join a query of the catalogs and cube_schemas.

SSIS might work but I wouldn't know where to start with that.

I run the query below on my server, I get one record per cube.

SELECT Cube_Name, LAST_DATA_UPDATE

FROM OPENQUERY(SSAS_METADATA, 'SELECT * FROM $SYSTEM.MDSCHEMA_CUBES')

WHERE CUBE_SOURCE = 1

I have a linked server on every sql instance that also has SSAS installed on the same box.

i can query the linked server for some of those attributes.

Alvin,

I tried running this on both the DB engine and the SSAS instance. The SSAS instance said The syntax for 'OPENQUERY' is incorrect.

The DB engine returned this error: Could not find server 'SSAS_METADATA' in sys.servers.

Lowell,

I think this is really close to what I need. I created the linked server, which is helpful. The result of the second query is the information I need but still is only returning one row(for one cube) instead of returning 21 rows.

Alvin,

Thanks, I've created the linked server. When I run that query in master on the DB instance I still just get one row for one cube instead of 21 rows for 21 cubes.

I didn't mention that in SSAS I have 21 cube databases. Each cube database has 1 cube associated with it. I don't know if that makes a difference.

That's why you're only seeing 1 cube. The query is only querying one database.

You need to query each database separately. You could do a union of all the queries.

Ah, that's it. I'm having trouble getting the syntax right for this. I created a temp table for the catalog names and then tried to get the last processed date.

CREATE TABLE #TempCatalogs(

Catalog varchar(50)

)

insert into #TempCatalogs

SELECT *

FROM Openquery(SSASLocalInstance, 'SELECT [CATALOG_NAME] FROM $SYSTEM.DBSCHEMA_CATALOGS')

--Find last process date for specific row with value BI_PSoft_TimeCard_Cube

SELECT Last_Schema_Update As lst,*

FROM Openquery(SSASLocalInstance, 'SELECT * FROM $SYSTEM.mdschema_cubes') AS a

WHERE convert(varchar(50),cube_name) = 'BI_PSoft_TimeCard_Cube'

This returns no results.

Can you log onto Analysis Services using SSMS and create a new DMX query:

SELECT * FROM $SYSTEM.DBSCHEMA_CATALOGS

What output do you see here?

Raunak,

This is perfect! I see all of the cubes on the server. Thanks so much!

OK, one more question. The query I ran shows the last processed date if you right click on the cube database properties on SSAS, which is not the same date if you drill down into the cube properties. What is the difference between those 2 properties?
