SSDB-8987, SSDB-7326

On Microsoft® Windows® 2008 R2, a SQL Server version 2012 instance with a name that contains inverted commas (''; (for example:'X641_ENT1') can encounter issues with the retrieval of WMI data. This is by design on the part of Microsoft.

Workaround: If WMI data is not retrieved, the instance name without the '' should be added in the field Service Name in the Agent Properties dashboard.

SSDB-8949

When editing the properties of the Foglight Agent Manager concentrator (Dashboards > Administration > Agents > Agent Status), the name of the Foglight Agent Managers should be entered in the Downstream FglAMs section exactly as they appear in the topology, under Home > Agents > All agents > <Agent name> > RMI data > Fglam host property.

SSDB-5542

Creating a user-defined collection with more than one SQL in it will not alert the user, however, only the first SQL in the collection will be executed.

SSDB-5248

Editing a user-defined collection results in periodic overlap of data.

SSDB-2455

User-defined collection names and fields must be entered in Latin characters (A to Z), without any special symbols.

SSDB-2379

When working with Global View while the screen resolution is set to 1024 by 768 pixels, it is advisable to switch to the browser's full view (F11 toggles between full and normal views in all browsers).

SSDB-2060

On SQL Server 2008, deadlocks on two different databases of the same instance become one chained deadlock.

Workaround: Implement trace flag -T1234

ODB-2984

In the Global Administration > User-defined Collections screen, it is possible to create two collections that bear the same name with a different capitalization (for example: MyCollection and Mycollection); however, the more recently created collection will not appear in the topology, nor will it be displayed on the User-defined Collections panel.

ODB-2829

When running user-defined collections on dynamic tables, deleted items are still kept in the topology. As a result, the number of rows displayed on the user-defined collections table will exceed the configured value for maximum allowed rows.

ODB-1606

Performing an upgrade process on a large environment (more than 50 agents) takes time to complete.

n/a

Need to wait for more than ten minutes between the upgrade of the Foglight Management Server and Foglight for SQL Server.

n/a

In environments configured to monitor SSAS agent only, when upgrading to version 5.9.2.1 or later, the upgrade process will fail.

Workaround: In the Administration > Agents > Agent Status dashboard, click Deploy Agent Package, then follow on-screen instructions to deploy the SSAS package manually.

n/a

On mixed Windows and Linux environments, SQL PI stops monitoring after upgrading the Foglight database cartridge to 5.7.5.30 and higher.

Workaround: Perform the procedure described in the Knowledge Article 212566. If you are upgrading from 5.7.5.30 (and higher) to version 5.9.2.1 or later, redo this procedure.

n/a

Monitoring Analysis services is supported only on Agent Managers running on Windows which must have a version of .NET 3.5 installed.

n/a

If the WMI exception "Format specifier '%s' " is entered in agent log the following workaround is recommended:

Workaround:

For Windows® Vista® and Windows Server 2008 or above: 

According to http://support.microsoft.com/kb/929851, the default dynamic port range for TCP/IP has changed in both versions. The new default start port is 49152 and end port is 65535. Subsequently, monitoring instances that run under these operating systems can be carried out by setting a static (fixed) WMI port in Windows Server.

For more information, see the Knowledge Article 114559 available at https://support.quest.com/kb/114559.

n/a

In cases when Foglight or the Agent Manager are installed on a VM the following need to be reserved:

  • Memory - the full amount of the required machine memory

  • CPU - the amount of CPU MHz

Execution Plan

Defect ID

Known Issue

SSDB-11283

Execution plan may not be resolved

SSDB-11582

Sometimes, query_hash is changed by SQL Server and generating a plan using the Generate button fails. SQLhash isn't found in XML so the screen displays No operation was found and the execution plan changes are missing.

SSDB-11657

Time range changes are not effecting the execution plan dashboard.

n/a

In the Execution Plan comparison popup, the date of the selected plan is the insert time to the SQL PI repository and not the execution time.

n/a

In the Execution Plan Comparison popup for statement - the estimated plan appears only as the selected plan on the left side. It cannot be selected from the list.

 

 


Third party known issues

The following is a list of third party issues known to exist at the time of this release.

 

Defect ID

Known Issue

FOGDG-650

The Foglight Agent Manager (FglAM) failed to restart when upgrading DB Cartridge, which is due to "Could not obtain a deployment lock" error.

Workaround: Perform the procedure described in the Knowledge Article 266110.

n/a

Anti-Virus Protection tools installed on Windows® may negatively impact CPU and system performance of machines running Foglight the Agent Manager and the SQL PI repository.
To reduce resource consumption it is highly recommended that you exclude the following directories from being scanned by the Anti-Virus tools:

  • <installation directory>:\Quest\<foglight>

  • <installation directory>:\Infobright

  • <installation directory>:\Quest\<FoglightAgentManager>

n/a

WMI-related issue

Problem: WMI support is affected by the firewall

Workaround: For Windows versions prior to Windows 2008/Vista, use the following steps:

  1. Open TCP port: 135.
    WMI by default uses the port range 1024 to 5000.

  2. Open up a range of ports above port 5000.
    Port numbers below 5000 may already be in use by other applications and could cause conflicts with your DCOM applications. It is recommended to have at least 100 ports opened, as several system services rely on these RPC ports to communicate with each other.

  3. Add the registry key, including additional ports.

    • Use the RPCCfg.exe (Windows Resource Kits) by running: rpccfg.exe -pe 5009-5009 -d 0

    • Manually add the registry keys under: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Rpc\Internet

For Windows Vista® and Windows Server 2008:

According to Microsoft® http://support.microsoft.com/kb/929851, the default dynamic port range for TCP/IP has changed in these versions. The new default start port is 49152 and end port is 65535.

Subsequently, monitoring instances that run under these operation systems can be carried out by using either of the following options:

  • Configure the firewalls to allow traffic between servers in the dynamic port range of 49152 through 65535 (less secure).

  • Limit the port range that is used in each monitored server.

n/a

As a result of the change introduced in Java 6 update 29 to how data is sent to databases, users may experience connection failures when using the Microsoft JDBC Driver for SQL Server® to connect to SQL Server. This interoperability enhancement is available in the following SQL Server versions:

  • SQL Server 2012 Production version and later

  • SQL Server 2008 Service Pack 3 Cumulative Update 4

  • SQL Server 2008R2 Service Pack 1 Cumulative Update 6

  • SQL Server 2008R2 Service Pack 2

n/a

Third Party Limitations

Monitoring an SQL Server instance that resides on a Windows 2008R2 or higher requires a workaround as follows:

  1. Browse to https://support.quest.com/ and log in

  2. Perform solution https://support.quest.com/kb/SOL65870

n/a

Some base values are not updated when using the Win32_PerfRawData_PerfDisk_LogicalDisk WMI class to calculate performance data in Windows Vista or in Windows Server 2008, because this class does not contain the PercentDiskTime_Base metric.

Workaround: A hotfix is available on Microsoft site, http://support.microsoft.com/kb/961435/en-us.

n/a

Due to a known Microsoft issue (https://support.microsoft.com/en-us/kb/3036328), on SQL Server instances version 2014 the SQL text presented may be truncated.

n/a

The Windows System Center 2012 Endpoint Protection tool may negatively impact CPU and system performance of machines running Foglight and the Agent Manager. To reduce resource consumption it is highly recommended that you exclude the following directories from being scanned by the tool:

  • <installation directory>\Quest\<foglight>

  • <installation directory>\Infobright

  • <installation directory>\Quest\<FoglightAgentManager>

n/a

SQL's and execution plans may not be collected on SQL Server 2014 as a result of a Microsoft bug

"The values of column query_hash and query_plan_hash are NULL for DMV sys.dm_exec_requests in SQL Server 2014"  http://support.microsoft.com/kb/2953592

n/a

The Foglight Time Bar Chart click event does not work with Chrome version 40.x.x.x and 39.x.x.x. https://code.google.com/p/chromium/issues/detail?id=428308

 

Workaround for all missing WMI metric cases

In some cases, running the command: %windir%\system32\wbem\wmiadap.exe /f in Windows' command-line (CMD) may solve the problem of missing WMI classes. This command parses all the performance libraries on the system and refreshes the Performance Counter Classes. For further details, see http://msdn.microsoft.com/en-us/library/aa394528%28VS.85%29.aspx

 


Upgrade and compatibility

Upgrade and compatibility

A direct upgrade to Foglight For SQL Server 5.9.4.20 is only available from version 5.7.5.x or above. Customers that are running 5.7.x of the product must first upgrade to version 5.7.5.x and then upgrade to version 5.9.4.20. A direct upgrade to Foglight for SQL Server 5.7.x is only available from version 5.5.8 or later. Customers that are running earlier versions of the product must first upgrade to version 5.5.8 and then upgrade to version 5.7.x.

For example, if your Foglight for SQL Server is version 5.5.8 and you are going to upgrade to version 5.9.4.20, the upgrade path will be 5.5.8 > 5.7.x > 5.7.5.x (or above) > 5.9.4.20.

 

Foglight for SQL Server 5.9.4.20 requires:

  • Management Server version 5.9.2, 5.9.3, or 5.9.4
