Method Detail

startWorkerProcesses

void startWorkerProcesses(GrinderProperties properties)

Signal the worker processes to start.

Parameters:

properties - Properties that override the agent's local properties.

startWorkerProcessesWithDistributedFiles

void startWorkerProcessesWithDistributedFiles(Directory distributionDirectory,
                                            GrinderProperties properties)
                                              throws ConsoleException

A variant of startWorkerProcesses(net.grinder.common.GrinderProperties) that checks the properties are reasonable for the distribution directory, and adjusts the supplied properties to have the appropriate relative paths.

Parameters:

distributionDirectory - The distribution directory.

properties - The properties. If the associated file is in the distribution, the agent doesn't reload the distributed copy. However,it uses its location to resolve any relative grinder.script path.

Throws:

ConsoleException - If the grinder.script property is set to a relative path outside of the distribution directory (e.g. ../foo.py.

ConsoleException - If an error occurred calculating file paths.

Since:

3.11

resetWorkerProcesses

void resetWorkerProcesses()

Signal the worker processes to reset.

stopAgentAndWorkerProcesses

void stopAgentAndWorkerProcesses()

Signal the agent and worker processes to stop.

addProcessStatusListener

void addProcessStatusListener(ProcessControl.Listener listener)

Add a listener for process status data.

Parameters:

listener - The listener.

getNumberOfLiveAgents

int getNumberOfLiveAgents()

How many agents are live?

Returns:

The number of agents.
