Load Agents

Load Agents are computers emulating virtual users
in the distributed test, orchestrated by this controller.

To create a Load Agent:

1. On a remote computer, install StresStimulus, and in the
StresStimulus menu -> Agent Options, enable Agent Mode.

2. On this computer, add a connection to the Load Agent.

Property

Description

Agent NameThe Load Agent Name
StresStimulus versionThe version of StresStimulus installed on the agent
Host / IP AddressThe Load Agent Host - Enter a network computer name or IP address without "//". Example: AGENT1 or 10.2.2.169.
PortThe TCP port used by the controller to communicate with this agent. The default port is 49998.
Mix WeightRelative number of VUs (in units or percents) emulated on the Load Agent. To disable the Load Agents, set its mix weight to zero.
Allocate at least one thread per VU

Starting thread count is the number of threads created automatically when the test is launched. By default, it is equal to the number of VUs. If more threads are needed, the load engine will gradually create more threads while checking available system resources. Select No to allow .NET Framework to allocate a default (typically smaller) number of starting threads.
