Introducing Load Manager Rules

Administrator-defined rules provide the framework to determine server load. For example, you can set the rule called server user load to be considered full at 100 users. When this limit is reached, the server is not available for additional connections.

The rules included in Load Manager are:

•Application user load

•Context switches

•CPU utilization

•Disk data I/O

•Disk operations

•IP range

•Memory usage

•Page faults

•Page swaps

•Scheduling

•Server user load

Load evaluators are made up of one or more rules and their load settings. You create load evaluators to perform customized load management tasks and then attach them to servers. You can create as many load evaluators as you need for optimum server or published application performance. However, each server can have only one load evaluator attached to it. Load evaluators can vary on each server, and each load evaluator can contain any combination of rule types and values.

Working With Load Evaluators

The Default and Advanced load evaluators are predefined evaluators that cannot be modified. The Default load evaluator contains one rule—server user load—that reports a full load when 100 users log on to the server. The Default load evaluator is attached to your server by default when you activate your Advanced or Enterprise Edition license, enabling Load Manager. You can create new load evaluators for your specific needs.
