Resource Manager Components

Resource Manager Components

Resource Manager relies on the following three components to gather, manage, and maintain data:

• Farm Metric Server The farm metric server is responsible for collecting and interpreting farm-wide metric information from the zone data collector and reporting alerts or alarms if metric thresholds are exceeded. By default, this is the first server where you install Resource Manager. The second server on which you install Resource Manager is designated as the backup Farm Metric Server.

  Because Farm Metric Servers retrieve updates from the zone data collector every 15 seconds, Citrix highly recommends that the zone data collector also be designated as the Farm Metric Server.

• Database Connection Server You select and configure this server to receive summary information once a day from each of the Presentation Servers in the farm. This information is then written by the Database Connection Server into the Summary Database. It is recommended that the Database Connection Server be configured on an MPS server with relatively low load to ensure optimal performance.

  The storage of historical metric information is an optional component of Resource Manager. If historical data is not going to be maintained , the Database Connection Server is not required.

• Summary Database When historical data is retained for Resource Manager, it is stored in the Summary Database. Unlike the Data Store for the Citrix Presentation Server farm, the Summary Database for Resource Manager must be deployed on either a Microsoft SQL Server or an Oracle database.
