Method Detail

getAgent

org.rhq.core.domain.resource.Agent getAgent()

Returns the agent domain object which provides the information about the agent.

Returns:

agent information

startSending

void startSending()

Puts this agent client in "sending mode" which enables this client to begin sending messages to the agent. Calling this method will immediately begin sending messages that were flagged as guaranteed delivery and have yet to be successfully sent (that is, messages spooled will be flushed out to the agent).

stopSending

void stopSending()

Stops the agent client from sending messages. Any messages sent asynchronously with guaranteed delivery will be spooled and sent the next time an agent client is started.

ping

boolean ping(long timeoutMillis)

Returns true if the agent is up and this client can communicate with it. This will return false if, for any reason, the agent cannot be pinged (which could mean the agent is down, or a network problem has occurred that prohibits the client from reaching the agent).

Parameters:

timeoutMillis - the amount of time, in milliseconds, the caller wants to wait before considering the agent down

Returns:

true if the agent can be pinged; false if this client cannot communicate with the agent for some reason
