All Implemented Interfaces:

AgentInterface, RequestAgentInterface, HasStateMachineModel, java.lang.Runnable

public class LogViewerPage
extends RequestAgent
implements java.lang.Runnable

This agent registers itself into the ServiceManager and accepts http requests to view information stored in log files. Given a directory, this agent will look for all the files in that directory and treat them as log files. The agent uses a mapping which provides information about how these files should be displayed. The logfile mapping maps a name to a text pattern. The agent will display the names and the matching lines of the log files.
