Document Version

This guide was written based on the 6.0.6972.0 version of
the Monitoring Pack for Windows Server Operating System.

Changes in This Update

Unless explicitly noted, these updates apply to all
operating system versions supported by this Monitoring Pack:

• Updated the Cluster shared volume
  disk monitors so that alert severity corresponds to the monitor state.
• Fixed an issue where the
  performance by utilization report would fail to deploy with the message “too
  many arguments specified”.
• Updated the knowledge for the
  available MB monitor to refer to the Available MB counter.
• Added discovery and monitoring of
  clustered disks for Windows Server 2008 and above clusters.
• Added views for clustered disks.
• Aligned disk monitoring so that all
  disks (Logical Disks, Cluster Shared Volumes, Clustered disks) now have the
  same basic set of monitors.
• There are now separate monitors
  that measure available MB and %Free disk space for any disk (Logical Disk,
  Cluster Shared Volume, or Clustered disk). NOTE: These monitors are disabled by default for Logical Disks, so you will need to enable them.

• Updated display strings for all
  disks to be consistent, regardless of the disk type.
• The monitors generate alerts when
  they are in an error state. A warning state does not create an alert.
• The monitors have a roll-up monitor
  that also reflects disk state. This monitor does not alert by default. If you
  want to alert on both warning and error states, you can have the unit monitors
  alert on warning state and the roll-up monitor alert on error state.
• Fixed an issue where network
  adapter monitoring caused high CPU utilization on servers with multiple NICs.
• Updated the Total CPU Utilization
  Percentage monitor to run every 5 minutes and alert if it is three consecutive
  samples above the threshold.
• Updated the properties of the
  Operating System instances so that the path includes the server name it applies
  to so that this name will show up in alerts.
• Disabled the network bandwidth
  utilization monitors for Windows Server 2003.
• Updated the Cluster Shared Volume
  monitoring scripts so they do not log informational events.
• Quorum disks are now discovered by
  default.
• Mount point discovery is now
  disabled by default.

This version of the Management Pack consolidates disk
monitoring for all types of disks as mentioned above. However, for Logical
Disks, the previous Logical Disk Free Space monitor, which uses a combination
of Available MB and %Free space, is still enabled. If you prefer to use the new
monitors (Disk Free Space (MB) Low Disk Free Space (%) Low), you must disable
the Logical Disk Free Space monitor before enabling the new monitors.

The default thresholds for the Available MB monitor are not
changed, the warning threshold (which will not alert) is 500MB and the error
threshold (which will alert) is 300MB. This will cause alerts to be generated
for small disk volumes. Before enabling the new monitors, it is recommended to
create a group of these small disks (using the disk size properties as criteria
for the group), and overriding the threshold for available MB.

Due to a glitch, the version of the MP published in the
in-product catalog that you see in the SCOM UI is 6.0.6970.0. This will be
updated in the coming days. The 6970 version is upgradeable to 6972 and has the
same functionality. We prefer that customers use the 6972 version, which is the
officially released version.
