Closed Feature: Realtime Server Status report does not work when connecting to SQL 2008 [19079]

amitban — Thu, 16 May 2013 11:18:23 GMT

Reason: Column cpu_ticks_in_ms of view sys.dm_os_sys_info was replaced with ms_ticks in SQL 2008 and higher.
SQL Nexus Version: 3.0.0.0

Hi,

I researched into this since I used this report frequently for monitoring our servers and kind of fixed it for myself by modifying the Report until seemed to work (although I am not sure if the data being returned now is really correct, someone will still have to verify this).

I am providing my modified version as attachment. Tested with SQL 2005 and 2008 R2.
I'd be happy if my modifications turn out to be correct and if they would make it into a future SQL Nexus release.

Regards,
Marc

When I tried to run these 2 reports I get an error that 'The database doesn't have necessary data to run the report'. I later discovered that this is due to the fact that the collation set of the server I loaded the sqldiag data on was case sensitive. When I loaded this data onto a server where the server collation set was case insensitive, these reports started working flawlessly.

I am using SQLNexus to trace a SQL2000 SP4a database instance. I am unable to use any but the ReadTrace_Main report, but that is okay for what I'm doing. The issue I encounter is when I select 'Unique Statements' from the top of the report the following error is thrown: 'Exception: Must Declare Scalar Variable @StartTimeInterval' Unique Batches work and I'm collecting the event start time/end time.

Issue addressed in higher version of RML Utilities.

I was receiving exit code 26 when I manually set the permissions on all of the *.trc files and now I receive ReadTrace exit code: -2. I cannot find any information on this error.
Comments:

Marking issue as closed as this is a by-design behavior and not related to RML Utilities.

This is not a bug! SQL profiler trace files are generated by the pssdiag or sqldiag utility depending on the tool that you are using to collect the data. SQLDIAG will apply ACLs on the trace files as documented here: http://blogs.msdn.com/b/psssql/archive/2008/06/25/how-it-works-trace-trc-file-security.aspx

Folder permission inheritance doesn't happen for security reasons.

I have resolved my issue, but this needs to be resolved as a patch I would believe. First of all my trace files (created by the perf scripts) had double underscores in them. Once I removed the double underscores and added my user account as full control on the tracefiles (not sure why they did not inherit the folder permissions) the import was successful. I have spoken with others who said they noticed this same buggy problem.

I try to collect statistcs using PSSDIAG, I have following error in the SQL_2008_Perf_Stats_Snapshot_Shutdown.OUT file

-- top 10 logical reads by query_hash --
Sqlcmd: Error: Microsoft SQL Server Native Client 10.0 : Unspecified error

I cannot find any more information in log files.

What else can I do to diagnose the problem ?
Comments: ** Comment from web user: amitban **

The most probable cause is that the data collection ended before that output was captured. You can open the .sql file for that script and collect the output manually.

Commented Issue: BLG file import broken in Windows 7 [17449]

rich_mccloud — Thu, 26 Jan 2012 16:17:17 GMT

Hi,

It looks like the BLG file import is broken in Windows 7 (and Win 2008 R2). The error message is about a failed connection to SQL Server from the Performance Data Helper (PDH) so I'm guessing they changed the way relog works from the previous OS versions. Could someone have a look to see if its a quick fix?

Thanks,

Christian
Comments: ** Comment from web user: rich_mccloud **

I also ran into this issue in Win7 x64...the problem was resolved by starting SQL Nexus using the 'Run as Administrator' option...obviously UAC is getting in the way of the BLG import proces.. Hope this helps.

Amitban I understand and know this is strange, but I checked the model DB and the AutoClose option is set to OFF.
When I create manualy a DB, it creates with the AutoClose option set to OFF.
However when SQLNexus creates a DB, it creates with AutoClose option set to ON.

I think the SQLNexus database is being created with AutoClose option set to ON because your model database has that property set. We don't explicitly set AutoClose to ON when creating a new Nexus database.

Hi, I had the same login error, and I found SQLNexus create DBs with "AutoClose Option = True".
Changing "AutoClose Option = False" I solved my login problem.

I hope this can help.

You can reduce the time range for which the data is being fetched using the Parameters tab in SQL Nexus.

Hello. I have the same issue while trying to view details of a query. This happens also in 3.0.
Are there now available some options to set the timeout parameters?

I also tried the below Sol but the tables below are missing in the database
tbl_Requests
tbl_blocking_chains
tbl_notableActiveQueries
Unable to view the Blocking and Wait Statistics OR Bottleneck Analysis reports or getting the error “Database doesn't have the necessary data to run this report”.

The data for the above report is based on the SQL Server 2005/2008 Perf Stats script output depending on the version of the SQL instance that you are collecting data from. The file that normally has the data for the above reports to be generated will have the following naming convention: <ServerName>__SQL_2005_Perf_Stats_Startup.OUT or <ServerName>__SQL_2008_Perf_Stats_Startup.OUT. Ensure that this file has collected at least two snapshots of the outputs of the T-SQL queries present in the SQL Server 2005/2008 PerfStats script. The check that is done to report this error is to check if data is present in the following tables in the Nexus database:

tbl_Requests
tbl_blocking_chains
tbl_notableActiveQueries
