Resource Manager Overview

Resource Manager Overview

As with any enterprise-level system, resource monitoring is an integral part of maintaining optimal performance and determining expansion needs and growth. Resource monitoring is one of your most useful tools when you need to justify hardware upgrades and expansion.

Resource Manager is a Citrix Presentation Server Enterprise Edition component that is designed to monitor resources such as CPU and memory on a Presentation Server. It allows you to generate detailed reports that provide you with information about how a server is performing during certain times of the day. It is also a very useful tool because of its historical data retention option, which allows you to run a report to determine the server's resource usage at any give date and time.

Resource Manager uses metrics to determine a resource's current load. Metrics are evaluation agents or performance-measuring units based on the operating system's performance counters. Metrics can be attached to a resource to measure its current load and report it back to Resource Manager. These metrics can be configured to alert the Citrix administrator when certain thresholds are reached so that steps can be taken to address any concerns.

Alert

Expect to see more questions on Resource Manager in the 223 exam compared to the 256 exam. You should have a basic understanding of the technology for both, but Citrix is currently working to develop a more thorough (and separate) exam to cover Resource Manager and its use in a production Presentation Server environment.
