This test reports statistics pertaining to the different applications executing on a Citrix Metaframe XP server and their usage by Citrix clients. One set of results is reported for each application.

Note:

This test will report metrics only if the XenApp server being monitored uses the .Net framework v3.0 (or above).

Measurement	Description	Measurement Unit	Interpretation
Number_of_processes	Number of instances of the published application currently executing on the Citrix server	Number	Indicates if too many or too few instances corresponding to an application are executing on the host. The detailed diagnosis capability, if enabled, lists the users, their corresponding process Ids, and the CPU and memory utilization (in %) of each of the processes.
Cpu_util	Percentage of CPU used by the published application	Percent	A very high value could indicate that the specified application is consuming excessive CPU resources.
Memory_util	This value represents the ratio of the resident set size of the memory utilized by the application to the physical memory of the host system, expressed as a percentage.	Percent	A sudden increase in memory utilization for an application may be indicative of memory leaks in the application.
Handle_count	Indicates the number of handles opened by this application.	Number	An increasing trend in this measure is indicative of a memory leak in the application.
No_of_threads	Indicates the number of threads that are used by this application.	Number
Virtual_memory_used	Indicates the amount of virtual memory that is being used by this application.	MB
IO_data_rate	Indicates the rate at which this application is reading and writing bytes in I/O operations.	Kbytes/Sec	This value counts all I/O activity generated by an application and includes file, network and device I/Os.
IO_data_oper_rate	Indicates the rate at which this application is issuing read and write data to file, network and device I/O operations.	Operations/Sec
IO_read_data_rate	Indicates the rate at which this application is reading data from file, network and device I/O operations.	Kbytes/Sec
IO_write_data_rate	Indicates the rate at which this application is writing data to file, network and device I/O operations.	Kbytes/Sec
Page_fault_rate	Indicates the total rate at which page faults are occurring for the threads of this application.	Faults/Sec	A page fault occurs when a thread refers to a virtual memory page that is not in its working set in main memory. This may not cause the page to be fetched from disk if it is on the standby list and hence already in main memory, or if it is in use by another process with whom the page is shared.
