public JabbixRequest(AgentServer srv,
                     Socket sock)

Creates a request task object with the specified parametres.

Parameters:

srv - a metric agent server using to get the suitable metric agent for a key being requested

sock - a connected socket to read the request data from and send the retrieved metric value to

Method Detail

run

public void run()

Starts the request process. If the command parameter isn't set on the request process start, then an attempt is made to read the command from the socket and parse it. If the command is parsed successfully the parsed and command properties are set. Then the command is processed. If it is identified as a metric key then a metric agent is requested from the agent server and the fresh metric value is retrieved from it. The new metric value is then sent to the requester as a data response.
