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

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)

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

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 2012 R2: Update Rollup 7

Microsoft has announced the release of U7 for SCOM 2012 R2, this update was originally delayed due to technical issues but is now available here:

This update contains many fixes which are listed below:

  • The home page link in the Web Console Noscript.aspx file is vulnerable to cross-site scripting (XSS)

    A security vulnerability exists in the Web Console for System Center 2012 R2 Operations Manager that could allow elevation of privilege if a user goes to an affected website by using a specially crafted URL. This fix resolves that vulnerability. For more information, see Microsoft Security Bulletin MS15-086.

  •  “Agents by Health State” report shows duplicate entries and inconsistent data

    Sometimes a single agent has multiple entries displayed in the “Agents by Health State” report. The fix for this issue makes sure the most recent state of the agent is displayed in the report.

  • Dependent tables are not groomed (Event.EventParameter_GUID table)

    The following issues are fixed:

    • In a database, the grooming of certain MT$X$Y tables were missed because of the filtering logic. Therefore, the tables were never groomed. There were scenarios in which lots of unwanted data was stored in these tables. This issue is now fixed, and data is groomed data from these table. This results in performance gains because there is less data from which to query.
    • In Data Warehouse, the grooming of certain tables was missed occasionally because current logic expects the rows to be returned in a certain order. This issue is now fixed, and the grooming of these tables will not be missed. In some scenarios, millions of rows were stored in these tables. This issue is now fixed. Data is now groomed from these tables. This results in performance gains because there is less data from which to query.
  • Management Packs do not synchronize between management servers

    In a SQL AlwaysOn setup, the SQL in the times of failover does not acknowledge the notifications that are registered by SCOM. This leads to inconsistent data in the environment, and the changes in management pack are not reflected in the whole environment. This update resolves this issue.

  • Leaked transaction causes over 100 SPIDs in SCOM database to be permanently blocked by the “p_DataPurging” stored procedure 

    Sometimes, because of a leaked transaction in the p_DataPurging stored procedure, the SPID becomes stuck. This causes other SPIDs to be blocked, and SCOM is brought to a standstill. This issue is fixed in this update. The fix prevents other SPIDs from being blocked.

  • Operations Manager SDK crashes because of SQL errors when QueryResultsReader.Dispose is called

    The Operations Manager SDK could potentially crash when it disposes of a database connection in some scenarios. Additionally, you receive an error message that resembles the following:

    Exception object: 00000004058197a0
    Exception type: System.Data.SqlClient.SqlException
    Message: A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 – An existing connection was forcibly closed by the remote host.)
    InnerException: System.ComponentModel.Win32Exception, Use !PrintException 0000000405819050 to see more.

    This update handles these scenarios gracefully.

  •  You can’t view dashboard performance counters that are created by using the TCP Port Monitoring template

    When you use the TCP Port Monitoring template to monitor network connectivity and the availability of local and remote assets, the template is missing a write action to the data warehouse. With the update, you can present this information on dashboards.

  • Dynamic inclusion rule is added to a group definition unexpectedly if an explicit member instance of the group disappears

    If all the explicit member instances of the group disappear, a dynamic rule is added to the group unexpectedly. With the update, no dynamic rule is generated in these situations.

  •  You can’t create group by using the SQL Server 20XX Installation Seed

    On the Dynamic Members tab of the Group Creation wizard, if you have a host class of your desired class, and if you try to select the inherited property of the host class, group creation fails. For example, if you select the Display Name(Object) property of Host=Windows Computer of the Management Server class on the Dynamic Members tab, group creation fails, and you receive the following exception:

    Processing the template failed. See inner exception for details.
    Verification failed with 1 errors:
    ——————————————————-
    Error 1:
    Found error in 1|StressCollectPerformancecounterMP|1.0.0.0|UINameSpaceb2240e1340254758bc3a0f1bd0082f4d.Group.DiscoveryRule/GroupPopulationDataSource|| with message:
    The configuration specified for Module GroupPopulationDataSource is not valid.
    : Cannot find specified MPSubElement DisplayName, on MPElement= Windows!Microsoft.Windows.Computer, in expression: $MPElement[Name=”Windows!Microsoft.Windows.Computer”]/DisplayName$

    This update resolves this issue.

  • Add MPB support to the SCOM online catalog

    The Management Pack catalog supports only those management packs that have the .mp extension and not the .mpb file-name extension. When this feature is implemented, the Management Pack catalog now supports MPB files.

    This update helps include management packs such as Azure Management Pack and SQL Management Pack on the Management Pack catalog that were not featured because of the .mpb file-name extension.

  • Active Directory Integration in Perimeter Network fails when there is only an RODC present

    When Active Directory Integration is enabled, the SCOM agent cannot talk to an RODC to obtain SCP information and instead looks for a RW domain controller. With this update, the Agent obtains SCP information from the RODC if information is available.

  • System Center Operations Manager subscriptions that use the filter to search for specific text in the description (of the message) do not work

    When you create a message subscription by using a criterion that contains specific text in the message description, no alerts were received through notifications. With this update, you receive notifications when the message description has specific text.

  • CLR load order change

    The current behavior for agents is to choose a CLR version based on the operating system version. For Windows Server 2012 and newer, the .NET Framework 4.0 is loaded. For operating systems older than Windows Server 2012, the .NET Framework 2.0 family is loaded. On management servers, the .NET Framework 2.0 family is loaded. This essentially maps the .NET Framework version used to the version available out-of-box on the server. The problem with the current behavior is that even if the Management Pack author knows that .NET Framework 4.0 is present on the system, it cannot be used.

    In the new behavior, the agent loads the .NET Framework 4.0 if it is available else it falls back to the .NET Framework 2.0.

  • Problems in obtaining monitoring objects by using “managementGroup.EntityObjects.GetObjectReader”

    In large System Center Operations Manager installations, when entity objects under a management group are retrieved by the object reader by using buffered mode, the object reader sometimes encounters System.Collections.Generic.KeyNotFoundException messages. With this update, the object reader ignores the invalid objects if they are not available.

  • The “Threshold Comparison” setting in the consecutive-samples-over-threshold monitor cannot be configured

    Although you configured the Threshold Comparison setting in the consecutive-samples-over-threshold monitor, the conversion of the Threshold float value from the management pack was incorrect for the German locale and caused monitor configuration failures. This issue is now fixed in this update for every supported locale.

  • Agentless Exception Monitoring (AEM) causes the Health Service to crash because the maximum path length of 248 character is exceeded

    When AEM client monitoring is turned on, sometimes the Windows error reporting file is created in a large file hierarchy. In scenarios in which the path is longer than 248 characters, AEM monitoring was causing the Health Service to crash. This issue is fixed.

  • After you update management packs, the newly added default (visible) columns to view are not visible automatically

    The first time that a view is opened on the console, registry keys are written in the HKEY_Current_User hive. The customization settings for the user are written in the registry. If the default view changes, the customization settings in the registry are not updated to reflect the new defaults. This update adds the newly added default column in the view.

  • Branding update

    Updates the “Operational Insights” name to “Operations Management Suite” in the System Center Operations Management console.

 

UNIX and Linux Management Pack

  • In some cases, Unix and Linux agents report incorrect CPU Processor Time

    The Unix and Linux agents use Percent IO Wait Time when calculating the Percent Processor Time for a CPU object. The agents no longer include the IO Wait Time in the calculation when they return Percent Processor Time.

Updates that are included in this update rollup

The following files are updated to support the following manageable operating systems.

Operating system Management pack
Debian 8 (x64) Microsoft.Linux.UniversalD.1.mpb
Debian 8 (x86) Microsoft.Linux.UniversalD.1.mpb
