New Post: Question about using ASTrace service against a tabular instance/model...

furmangg — Wed, 27 Mar 2013 02:59:31 GMT

I would use ASTrace and make sure you use a .tdf which just requests the minimum events and columns you need. I think you're going down the right path.

Thanks for the reply!

So if I wanted what is essentially the trace profiler info (what query ran when and by whom), logged to a database for usage statistics collection purposes, what would you recommend?

thanks again,

furmangg — Mon, 25 Mar 2013 14:09:16 GMT

I'm not sure if you can open what's saved to ASTraceTable in Profiler. The goal is just logging it to a SQL table without Profiler being the tool that's logging to the SQL table, since there's a cost for that GUI being open.

Generally people use ASTrace to log important trace events to a table. For example, you can log the Query Begin event and capture the MDX queries that are being executed.

To interpret it, I would either run a Profiler trace simultaneously and then compare ASTrace and Profiler to interpret what the numbers in ASTraceTable mean. Or you could also look at the following file (slightly different path depending on your version and instance name) to figure out what EventClass and EventSubclass mean:
C:\Program Files\Microsoft SQL Server\MSAS11.TABULAR\OLAP\bin\Resources\1033\tracedefinition110.xml

Hi,

I think I've got this installed and running correctly. When I browse my a tabular model in ssms, every field I drag onto the query pane results in a new row added to the ASTraceTable table.

But the columns in ASTraceTable aren't human-readable, by contrast with what I see when I run SQL Profiler.

The events and associated data mentioned in the ASTrace documentation, like QueryEnd, with its query text and so on, I see those in SQL Profiler trace. But in ASTraceTable, all I see are columns like EventClass, EventSubclass, IntegerData, and so on.

So my question is: how do I transform the data in the ASTraceTable into the more human readable version that SQL Profiler provides? What am I missing?

Thanks much,
sff

Even Iam facing the issue, Is this package is also compataible for ASTRACE Files in 2012. Because Iam getting the similar error when Iam running the package

New Post: Error encountering while stopping data Collection

scornik — Mon, 16 Jan 2012 08:21:31 GMT

Hi all,

Finally I have get rid off the final error also by "re-configuring" MDW database.

But now no error is occuring but after stopping "mdw.workload_runs" table is showing empty?

any idea?

Hi ,

I was able to get rid of 'SSASServerSSASInstanceName' scripting variable not defined." refencing from ">http://sqlsrvanalysissrvcs.codeplex.com/workitem/14885".

But still stuck in "Msg 208, Level 16, State 1, Server DACW0072\SQL2K8R2, Line 2
Invalid object name 'MDW.snapshots.performance_counters'." error.

Hi,

I found the root cause of the above problem: I hadn't enabled "Data Collection" and after enabling the above error goes away.

But, while stopping the collection I am encountering the following error:

From SSAS_perf

Any one have any idea?

I am getting the following errors while stopping the data collection:

After that If I try to start the data collection the following message appears:

From SSAS_perf

Can you help me out, what am I doing wrong? I am analyzing SSAS on same server.

New Post: ResMon Cube is empty

Glad you found a workaround that works for you. I have definitely seen the problem you mention before.

I believe the object activity DMV just shows activity since the last time the SSAS service started.

New Post: ResMon Cube is empty

tomerdg — Thu, 29 Dec 2011 11:59:22 GMT

I found the problem - the connection between the dims and the MeasureGroup are based on the processing-time "minute-wise". Perhaps because there are may cubes in my server, the different object dimension take more than a minute to process. Let's say the processing start at 14:26 - the dimensino key contains an object with the 14:26 key, but the MG runs 2 minutes later so the same object in the MG has the key of 14:28, and they don't match. I chaged the connection to be "hour-wise" and it fixed the issue ( as long as I don't start the process at 14:59 :).

BTW - does the object activity DMV contain data for each object since its creation? (i.e- the number of agg. hits is the total number an aggregation was hit since the object was created?)

thanks

I'm not sure what could be the problem. Feel free to post an issue under the issue tracker and attach the XMLA script for your modified cube.

New Post: ResMon Cube is empty

tomerdg — Wed, 28 Dec 2011 10:00:58 GMT

Hi,

First of all - thanks for creating this cube. It really seems like a good solution for monitoring the SSAS server.

I created the ResMon cube on my server. I processed it a few times (some of the times using the ProcessResMon.xmla), but when I browse the cube there's no data. All the measure groups partitions are indeed empty (estimated size 0), although rows do return when I run the DMV queries. The dimensions do have members and the Sessions cube is filled with data as well.

I should mention that I changed the solution a little bit - since the MemoryObject dim wouldn't process due to duplicate key error, I added the OBJECT_TIME_CREATED to its key. ( I figured that even if this causes a problem it should be limited to the memory-usage measureGroup).

Any help would be appreciated.

Thanks

Tomer

New Post: Analysis Trace Data?

furmangg — Sat, 24 Sep 2011 14:24:21 GMT

I believe Start_Collection.cmd is going to call Start_SSAS_Server_Trace.xmla which will begin logging trace events to a file. Then you'll need to run Load_SSAS_trace_data.dtsx to load the .trc files into SQL server for the reports to see them. But all this is documented in that word doc you mentioned.

Hello:

As per your word doc "A Solution for Collecting Analysis Service Performance Data for Performance Analysis.docx" As shown below.

'Using the Sample Reports to Query the Collected Data' on page-9 as state below.

You could also use these reports to compare a specified time period with a baseline. We have also used these reports to analyze an Analysis Services profiler traces sent to us by customers to determine the worst performing queries and to quickly identify the types of problems that the data reveals are the source of the problem for the poorly performing queries.

Thanks

furmangg — Tue, 20 Sep 2011 20:58:40 GMT

Can you elaborate? Which doc are you referring to? What type of information is your customer expecting to see?

There are a number of samples inside this "SSAS Community Samples" project on CodePlex. Which are you referring to?

aaditya2000 — Mon, 19 Sep 2011 22:55:37 GMT

hello:

In your doc you mentioned that you have used this report for traces collected for your customer.

My question is, if do profiler traces for Analysis Server, then how i can use your report to display results for this trace.

Any sample about how to modify & use for new traces is greatly appreciated.

Thanking in advance.

Thanks

I figured out the problem, I had to run the package under 32 bit debug mode to make it work

Thanks for your help !

I took at look at this and my guess is that the red line is throwing an error, but the catch statement just absorbs the error so you don't see it. I would add a breakpoint inside the catch and then step through the code to see what error you're getting. Maybe sTraceFileName isn't pointing to a valid trace file or something? Or maybe that trace file is still being written to? My guess is that the exception you're seeing from your post above is from the line I highlighted in blue... so maybe the code above it didn't work as expected.

Dim issuccess As Boolean = True
Try
' Open the trace file as a reader
myTraceFile.InitializeAsReader(Me.Variables.sTraceFileName)
Catch goof As Exception
System.Diagnostics.Trace.WriteLine(goof.InnerException)
issuccess = False
End Try

Dim numfields As Integer = 0
If myTraceFile.FieldCount >= 1 Then
numfields = myTraceFile.FieldCount
Else
numfields = 17
End If

Oops. You can't put a breakpoint on a script component (i.e. a script in the data flow). So maybe just change the code to just throw the error instead of catching it temporarily.
