No Alert from SQL MP when clustered services go down

  • Статья

I recently ran into the following issue:

The SQL Server Management Pack has several monitors to monitor various SQL Services:

However, on a SQL Cluster, if one of these services is taken offline:

We don't get an alert from SQL (we do get a cluster alert saying that a cluster is offline), and the monitor stays healthy:

This happens because:

  1. By default, a Basic Service Monitor will only monitor services whose startup type is Automatic
  2. On a Clustered SQL instance, the service startup type will be set to Manual

To fix this, you simply need to set the "Alert only if startup type is automatic" override to "False" for the Clustered SQL Instances

Now, the health state is changed when the service is down and we are properly alerted:

NOTES:

  • The SQL Monitors affected by this are:

    • Microsoft.SQLServer.2008.DBEngine.ServiceMonitor
    • Microsoft.SQLServer.2008.ReportingServices.ServiceMonitor
    • Microsoft.SQLServer.2008.AnalysisServices.ServiceMonitor
    • Microsoft.SQLServer.2008.IntegrationServices.ServiceMonitor
    • Microsoft.SQLServer.2008.DBEngine.FullTextSearchServiceMonitor
    • Microsoft.SQLServer.2008.Agent.ServiceMonitor
    • Microsoft.SQLServer.2005.DBEngine.ServiceMonitor
    • Microsoft.SQLServer.2005.ReportingServices.ServiceMonitor
    • Microsoft.SQLServer.2005.AnalysisServices.ServiceMonitor
    • Microsoft.SQLServer.2005.IntegrationServices.ServiceMonitor
    • Microsoft.SQLServer.2005.DBEngine.FullTextSearchServiceMonitor
    • Microsoft.SQLServer.2005.Agent.ServiceMonitor

  • You must have at least version 6.0.6441.0 of the SQL Server Management Pack for this to work.  The latest version is 6.0.6460.0 and can be downloaded here.

  • If you manually create a Basic Service Monitor in the OpsMgr console, the "Alert only if startup type is automatic" override will not work.  You'll need to export the MP and edit the XML to add <CheckStartupType>true</CheckStartupType> to the monitor configuration (this is already done in the latest SQL MP):

Before change (not working):

<ComputerName>$Target/Property[Type="Windows!Microsoft.Windows.Computer"]/NetworkNam
e$</ComputerName>
<ServiceName>Messenger</ServiceName>
</Configuration>
</UnitMonitor>

After change (working):

<ComputerName>$Target/Property[Type="Windows!Microsoft.Windows.Computer"]/NetworkNam
e$</ComputerName>
<ServiceName>Messenger</ServiceName>
<CheckStartupType>true</CheckStartupType>
</Configuration>
</UnitMonitor>

    Interesting....just checked the SQL 2000 MP myself and CheckStartupType is not there.  So, for SQL 2000, you would need to do the following:
  1. Disable the current service monitor in the SQL 2000 MP
  2. Create a new service monitor in your custom MP.
  3. Modify the XML to include "<CheckStartupType>true</CheckStartupType>" I haven't verified this yet, but I believe that if you are using R2, the "<CheckStartupType>true</CheckStartupType>" will already be in the XML when you create a service monitor (of course, that doesn't fix the current SQL 2000 MP).

    You'll only want to target the SQL Cluster with this override....so it will only apply to the current active node of the cluster.  When setting the override, select "for a specific object of type: SQL 2005 DB Engine" and select your SQL cluster...or, create a group of the clustered DB Engines and target that group.  Again, the key is to target only the clustered DB Engines.

    Can you verify how the override is set?  Are you targeting the override at "SQL 2005 DB Engine" and selecting ONLY the SQL Clusters, and not the physical cluster nodes?

    I have tried input "$Target/Property[Type="SQL!Microsoft.SQLServer.DBEngine"]/ServiceName$" into the service name field as the SQL MP does. But got an error said "Unknown alias [SQL]" How to define such alias in my custom MP? Thanks!

    oh! really a good way!! Another small question: what is the difference between "SQL Server Windows Service Name" and "SQL Server Windows Service Name If Clustered Resource"? Thanks Again!!
