How to Enable Remote Control

 

Topic Last Modified: 2008-02-04

To run Exchange Load Generator from multiple clients, you can use the remote control feature to manage all the clients from one computer (called a master computer). You do this by changing the configuration file or by using the user interface.

noteNote:
Make sure that you start the Microsoft Exchange Load Generator Remote Agent service on the remote load generator before you start the simulation.

  1. In the LoadGenConfig.xml file (or whatever you named the file), locate the <RemoteProfile> tag followed by the <EnableRemoteDistribution> tag.

  2. Make sure that the value between the start tags and the end tags is "true".

  3. Add the following to the configuration file to run simulation on two computers:

    <EnableRemoteDistribution>true</EnableRemoteDistribution>

    <RemoteLoadGenerators>

    <RemoteLoadGenerator Name="Remote Load Generator 1"/>

    <RemoteLoadGenerator Name="Remote Load Generator 2"/>

    </RemoteLoadGenerators>

    <LoadBalancing>false</LoadBalancing>

    <PerfmonCountersRefreshTimeinSeconds>5</PerfmonCountersRefreshTimeinSeconds>

    noteNote:
    Although the master computer can also be configured as a load generator, we do not recommend that you do this. This is because the Exchange Load Generator counters will no longer be accurate.
    noteNote:
    If LoadBalancing is set to "true", users will be evenly distributed to remote load generators at the beginning and Exchange Load Generator will monitor the load on the remote client. Users will be reduced if the remote client is overloaded, or more users will be assigned if the remote client is underloaded. If LoadBalancing is set to "false", users will be distributed to remote load generators evenly, but load balancing will not be done.

  1. Open the user interface application.

  2. On the Remote configuration page, click Enable task engine to distribute the load to remote load generators.

  3. On the Remote configuration page, click Enable load balancing on remote load generators to enable or disable load balancing.

  4. From the drop-down list in Remote logging level, select the log level that you want.

  5. Add or delete load generators using the Remote Load Generators selection box.

  1. In the LoadGenConfig.xml file (or whatever you named the file), locate the <RemoteProfile> tag, and then the <LogLevel> tag that follows it.

  2. The default value of LogLevel is Off. This means no log file will be generated on the remote load generator. To enable the log file, type any of the following values depending on the log levels that you want: Information, Error, Warning, Verbose.

    • Information refers to informational messages, warnings, and error-handling messages.

    • Error refers to output error-handling messages.

    • Warning refers to output warnings and error-handling messages.

    • Verbose refers to output all debugging and tracing messages.

  1. In the LoadGenConfig.xml file (or whatever you named the file), locate the <RemoteProfile> tag followed by the <EnableRemoteDistribution> tag.

  2. Make sure that the value between the start tags and the end tags is "true".

  3. Change the file as follows:

    <EnablePerUserGroupDistribution>true</EnablePerUserGroupDistribution>

    <RemoteLoadGenerators>

    <RemoteLoadGenerator Name="Remote LoadGenerator 1">

    <UserGroups>

    <Name>UserGroup1</Name>

    </UserGroups>

    </RemoteLoadGenerator>

    <RemoteLoadGenerator Name="Remote Load Generator 2">

    <UserGroups>

    <Name>UserGroup2</Name>

    </UserGroups></RemoteLoadGenerator>

    </RemoteLoadGenerators>

    <LogLevel>Verbose</LogLevel>

    <PerfmonCountersRefreshTimeinSeconds>5</PerfmonCountersRefreshTimeinSeconds>

    <LoadBalancing>true</LoadBalancing>

</RemoteProfile>

noteNote:
You cannot have load balancing and EnablePerUserGroupDistribution turned on at the same time. This is because load balancing involves moving users around, and that would probably violate the user group definition for each remote load generator.
