What does Sealed and Unsealed Management Packs mean

What does Sealed and Unsealed Management Packs mean

• Management packs are either sealed or unsealed. A sealed management pack is a binary file that cannot be edited. An unsealed management pack is an XML file that can be edited. Sealed management packs should have an .mp extension, while unsealed management packs should have an .xml extension.

• In general, management packs obtained from an application or hardware device vendor are sealed.

Although you cannot change the settings in a sealed management pack, you can still customize the applied settings of a management pack after it is imported by using overrides or by creating additional settings such as rules, monitors, and tasks that supersede the management pack's default settings. All customizations that you create are saved to a separate management pack file.

Each management pack can contain any or all of the following parts:

• Monitors, which direct an agent to track the state of various parts of a managed component.
• Rules, which direct an agent to collect performance and discovery data, send alerts and events, and more.
• Tasks, which define activities that can be executed by either the agent or the console.
• Knowledge, which provides textual advice to help operators diagnose and fix problems.
• Views, which offer customized user interfaces for monitoring and managing this component.
• Reports, which define specialized ways to report on information about this managed component.
• Object discoveries, which identify objects to be monitored.

New Windows Server Operating System Management pack for Windows 2012 R2 version 6.0.7297.0

New Windows Server Operating System Management pack for Windows 2012 R2 Version 6.0.7297.0

• Microsoft has released a new MP for Windows Server which include 2012,2012 R2, Windows 2008

Following are the Fixes that has been done in this latest

• 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
