SCOM: Alerting on Exchange 2013 Database Failover

Leave a reply

As it turns out the Exchange 2013 MP will not be able to alert you should your Exchange 2013 databases fail over, this is by design, as Microsoft does not consider this condition to be an issue.

There is a great article by Scott at flobee.net which addresses this issue for Exchange 2010, it is quite simple to apply the same thinking for use with Exchange 2013. The event is the same, the target just needs to be Exchange 2013 server.

SCOM: The System Center Management service terminated with service-specific error %%-2130771964

Leave a reply

Just a quick issue which bares being noted.

A colleague of mine had an issue where the health service on one of his management servers would not start. The error displayed was “The System Center Management service terminated with service-specific error %%-2130771964″

The resolution is simple, rename the Health Service State folder and then start the service.

This issue is caused by corruption in the health service cache which is preventing the service from starting,

SCOM: Error in SNMP GET response from IP Address: Status: noSuchInstance(129)

3 Replies

Today I was addressing this error in the Operations Manager event log at one of my customers:

Error in SNMP GET response from IP Address: Status: noSuchInstance(129)

According to What Gets Monitored with System Center Operations Manager 2012 Network Monitoring this can be caused by several things:

Possible Resolutions

  • Stale Discovery Data – Device has been reconfigured since the last discovery and Operations Manager is attempting to monitor a component that no longer exists on the device.
  • If the device doesn’t support the workflow, then a solution is to disable the workflows utilizing the value for the device. This will prevent these workflows loading and failing in the future.
  • Possibly a device issue, try updating the Firmware and OS on the device
  • Possible a discovery issue where the instance is being discovered incorrectly.  For example Operations Manager is expecting to monitor a performance counter but this is a virtual interface and the counters are not present for the interface.  Try running a re-discovery for the device.

In my clients case the network devices in question did not respond to the information request of certain workflows.

I resolved the issue by creating a group and adding the ports which were not returning data to that group. Then I evaluated each of the event log errors for the name of the workflow that was executing the snmp get, see example below:

Log Name:      Operations Manager
Source:       Health Service Modules
Event ID:      11009
Error in SNMP GET response from IP Address: 10.11.11.1, Status: noSuchInstance(129).
One or more workflows were affected by this.
OID: .1.3.6.1.2.1.10.7.2.1.2.268
Workflow name: System.NetworkManagement.MIB2.NetworkAdapter.InputPacketBroadcastPct
Instance name: Port-37

There is a great reference at http://mpdb.azurewebsites.net which you can use to match up the workflow name to the corresponding rule or monitor. If I use the above example and search the page for System.NetworkManagement.MIB2.NetworkAdapter.InputPacketBroadcastPct I can see it correlates to a rule called Input Broadcast Packets Percentage (netcor) which I can override to turn off against the group I created earlier.

It can be a lengthy process and there are other causes which are easier to address so you will need to do some testing in each individual case.

SCOM: Updated Windows Server MP v6.0.7297.0

Leave a reply

Version 6.0.7297.0 of the Windows server management pack has been released and in available for download here.

Updates in this version:

  • In 2008, 2012 platforms, the “Logical Disk Free Space (%) Low” monitor do not alert as expected when free space is 0%. With this fix, this monitor will alert when free space is 0%
  • In all platforms, logical disks are un-discovered if we configure them as Asymmetric storage on Failover Cluster. With this fix, this issue will be resolved
  • The Windows Server OS Management pack collects logical disk size is megabytes. During discovery this value used to be assigned to integer property. When logical disk size is significantly large (for example, when disk is of several petabytes), in megabytes format it goes out of boundaries of integer type. As a result the workflow fails while trying to insert discovery data. To support large logical disk another double properties was introduced, since double type has much more wide values range. Old integer property with constant “-1” value is preserved for upgrade compatibility and marked as DEPRECETED
  • “Volume Mount Points on Dynamic Disks” aren’t discovered by Microsoft Windows Server 2012 Discovery MP. With this fix, this issue will be resolved
  • MP has been modified to not discover System Reserved volumes on Windows Server 2012 to ensure it is consistent with the rest of the OS versions

SCOM: Update Rollup for Microsoft Monitoring Agent

Leave a reply

Microsoft has released a new Update Rollup for the Microsoft Monitoring Agent it is available through windows update or via the catalog link in the KB article here.

Issues that are fixed in this update rollup

  • Support for Windows Server 2008 and Windows Vista. Add support for Windows Server 2008 and Windows Vista on-boarding to the Microsoft Operations Management Suite.
  • Maintain original identification after Operations Management Suite is disabled and then re-enabled or after agent is reinstalled. Preserve the identification of the system during upgrades or when enabling and disabling the Operations Management Suite. Previously, disabling and then re-enabling a connection to the Operations Management Suite caused a new agent identification to be generated.
  • Always use the Microsoft .NET Framework 4.0 for loading managed modules if it is available. Set a preference for the .NET Framework 4.0 when managed code is loaded in management packs. The .NET Framework 2.0 is used if the .NET Framework 4.0 is not available. Previously, the .NET Framework 4.0 would be used on Windows Server 2012, Windows 8, or later versions of Windows operating systems while the .NET Framework 2.0 was loaded on earlier versions of Windows.
  • Fix the Apply button that is not working in the Microsoft Monitoring Agent control panel.
  • Remove a dialog box that is displayed during a silent installation when a restart was required.

SCOM: Deleting a MP with a Microsoft.SystemCenter.SecureReferenceOverride dependency

3 Replies

This situation will occur when you try and remove a management pack that utilities a Run As account. You’ll get an error that the management pack is dependent on Microsoft.SystemCenter.SecureReferenceOverride and removing that can be a little bit painful.

Anyone one who has ever removed a management pack with a dependency knows the old method of exporting the management pack, removing the offending refference and importing it back again. The steps for Microsoft.SystemCenter.SecureReferenceOverride are slightly different but the principle is the same.

1. First you need to remove the Run AS account from the Run As Profile
2. Export the Microsoft.SystemCenter.SecureReferenceOverride management pack
3. Edit the management pack and remove the references as you would with any other dependency
4.  Increment the management pack version
5. Re import the management pack

Here is a nice method from Matthew Long which uses powershell and doesn’t require any XML editing.

The below is copied for my records, original posting here

  1. Open a powershell session with the Operations Manager module/snappin loaded.
  2. Type: $MP = Get-SCOMManagementpack -Name Microsoft.SystemCenter.SecureReferenceOverride
  3. Now we can view the referenced management packs by typing $MP.References
  4. From the list of items in the Key column, note down the alias of your MP you wish to delete.  If you are having trouble finding it, the Value column will list the full ID of the MP.
  5. Now that we know the MP alias, we can remove it from the Secure Reference MP by typing $MP.References.Remove(“yourMPAliasGoesHere“)
  6. Now we can verify the MP is valid by entering $MP.Verify()  to ensure there are no orphaned overrides, etc.
  7. Finally, we can save our changes by typing: $MP.AcceptChanges()
