Introduction to Resource Manager (RM)

What is Resource Manager, actually?
Resource Manager collects, displays and stores data about system performance, applications or process use.
Is this not exactly the same things that Performance Monitor (standard available in Windows) does?
Citrix RM definitely has some overlap with Performance Monitor, but adds some extra functionality to it.
These additional functionalities are the benefits of Resource Manager.
Real Time Watcher, on the monitored counters (called Metrics within Resource Manager) you can assign two thresholds (warning and error). If these thresholds are exceeded Resource Manager can warn you via several methods like SMS, E-mail or SNMP.
Resource Manager can store the collected data for a longer time. This makes it possible to generate reports based on current and past activity.
Resource Manager has an option to create billing reports based on self defined costs.
Resource Manager collects, besides the system counters, also Citrix specific data like Application usage, User activity and Farm information.
If your infrastructure already contains an advanced monitoring system like Tivoli NetView, HP OpenView, or CA Unicentre, these solutions provide the Network Manage component. This component ports the data from Resource Manager to the monitoring system, so the data is also available in those systems. Citrix also support this functionality for Microsoft Operations Manager (MOM).
