8.1.9 Management Cluster
The Management cluster has several different components that must be monitored for continued operation of the vCloud. A sample management dashboard is shown in Figure 66. The dashboard in the example monitors the following vCloud management components:
*SQL Server (vCenter/vCloud Director databases).
*vCenter Server.
*vCloud Director cell.
*vCenter Operations Manager.
*Chargeback.
*vCloud Networking and Security Manager.

The first widget is used to monitor the SQL database for database size and transactions metrics. The Hyperic agent is used to collect these metrics and display them in a scoreboard widget.
The following metrics are used for this widget:
*Metric used: Microsoft SQL Server 2008 (database SQL01-Server MSSQLSERVER).
*Databases: vCloud Director and vCenter (the SQL databases).

The following widget monitors the SQL Server free space on each logical operating system drive. This example uses the following drive letters:
*C:\ Operating system driv.
*D:\ SQL database files.
*E:\ SQL log files.
*F:\ SQL backup.
This example monitors free space available on each of the drives and configures alerts based on thresholds. The metric used is for the resource kind Virtual Machine, and data is collected using VMware Tools. This example uses the Scoreboard widget as shown in the following table.

The same metric can be used to create a widget that monitors the vCenter and vCloud Director cells for free space. Monitor the transfer folder free space of the vCloud Director cells. Using a Scoreboard widget you can create a widget as shown in the following figures. Note that the transfer folder mount point is monitored. The default mount point is /opt/vmware/cloud-director/data/transfer in the Linux operating system (vCloud Director cell).
Example Free Space Widget
 
You can use a Metric Graph widget to monitor historical CPU demand on the following infrastructure objects:
*SQL Server.
*vCloud Networking and Security Manager.
*vCloud Director cells.
*vCenter Server.
The following metrics are used to create the widget.
