134 MetaFrame Solutions Guide

ICA packets use TCP port 0x5D6 or 1494 using decimal notation. It is recognized

in Network Monitor by looking for the 5D6 in either the Source Port or

Destination Port address. A display filter can be set on the Source and Destination

port to show only 0x5D6 packets in Network Monitor.

Network Monitor is not the only place to get information about ICA traffic.

If you have connection problems, use MetaFrame Administration to monitor the

ICA connection status while a user attempts to log on.

ICA packets are encrypted. If an analysis of a trace is necessary to troubleshoot a

problem between the MetaFrame server and an ICA Client, save the capture data

to a file. Send this capture data to support personnel if the problem cannot be

resolved.

Performance Monitor

The hardware and software configuration used with a MetaFrame server has a

large effect on system performance as measured by user response time. The most

useful tool in tuning a MetaFrame server is Performance Monitor. Performance

Monitor is a graphical tool that collects and examines data concerned with system

activity. The overall performance of a MetaFrame server can be examined by

monitoring the following areas:

Processor(s)

Memory

Hard Disk(s)

Network

System throughput problems usually occur when demand for one of these

resources exceeds the supply. The available resources in this case are the

microprocessor(s), memory, hard disk(s), and networking hardware and software.

Finding out how user applications interact with each of these resources is a logical

first step when you start monitoring.

When monitoring a system, you are really monitoring the behavior of its objects.

In MetaFrame, an object is a standard mechanism for identifying and using a

system resource. Objects are created to represent individual processes, sections of

shared memory, and physical devices. Performance Monitor groups counters by

object type. A unique set of counters exists for the processor, memory, cache, hard

disk, users, processes, and other object types that produce statistical information.

Certain object types and their respective counters are present on all systems.

However, other counters, such as transport-protocol counters, appear only if the

computer is running the associated software.
