To accommodate routine application and database maintenance, you can use Load Management to schedule the availability of published applications on your servers. Load Management provides: Maximized system efficiency. Load Management balances published application loads across your server farm based on server or published application load limits set in load evaluators. This feature allows more efficient data flow in your server farm environment. Citrix default load evaluators. Load Management includes two load evaluators that work well in most server farm environments, simplifying your current load configuration without modification until you learn more about Load Management. Customization. Load Management includes a set of rules that you can use to create your own load evaluators, increasing server and published application performance in your server farm. Real-time monitoring. The Load Management Monitor tool lets you view the statistics monitored by your load evaluators after you attach them to a server or published application. Complete List of Available Rules for Load Evaluators Application User Load – Calculates load based on the number of users accessing a specific published application on the attached server. When the number is within the load and high thresholds, Load Management reports a load percentage based on the threshold values. When they exceed the limits set, Load Management reports 100% load. Context Switches – Calculates load based on CPU context switches. A context switch occurs every time the operating system switches from one executing process to another. When the number is within the load and high thresholds, Load Management reports a load percentage based on the threshold values. When they exceed the limits set, Load Management reports 100% load. CPU Utilization - Calculates load based on CPU Utilization. When the number is within the load and high thresholds, Load Management reports a load percentage based on the threshold values. When they exceed the limits set, Load Management reports 100% load. Disk Data I/O – Calculates load based on Disk I/O in Kilobytes. When the number is within the load and high thresholds, Load Management reports a load percentage based on the threshold values. When they exceed the limits set, Load Management reports 100% load. Disk Operations – Calculates load based on the number of disk operations per second. When the number of disk operations per second is within the load and high thresholds, Load Management reports a load percentage based on the threshold values. When they exceed the limits set, Load Management reports 100% load. IP Range – Enables or disables access to a published application based upon whether or not the OP addresses of the clients are within a specified IP address range(s). Load Throttling - Determines load based on user logon operations affecting server performance. If logon is an expensive operation (lots of scripts, etc.) then this should be set to High. To maximize load when one user logs on set to Extreme. This means that only one person can log on to this server at a time and other incoming connections will be denied until the logon operation for that user is complete. This helps to minimize the 9am logon effect where servers become loaded too quickly. Memory Usage – Calculates load based on memory utilization. When the memory utilization is within the load and high thresholds, Load Management reports a load percentage based on the threshold values. When the memory utilization exceeds the thresholds, Load Management reports a full load. Page Faults – Calculates load based on the number of page faults per second. A page fault occurs every time the operating system accesses physical memory that has been flushed to disk. Page Swaps – Calculates load based on the number of page swaps per second. A page swap occurs every time the operating system swaps physical memory to virtual memory on disk. Scheduling – Schedules the availability of selected server or pubished applications. It sets the weekly days and hours during which the server or published application is available to users and can be Load Managementd. For example, you can use this rule to precent access to sensisitve data outside of regular business hours. Server User Load – Allows your load evaliator to calculate load based on the number of users on an attached server. When the number of users is less than or equal to the high threshold, Load Management reports a load percentage based on the threshold value. *
