Method Details

controlProbe

public void controlProbe(BasicTcpControlEvent event)
                  throws RemoteControlFailedException

Convenience method for control events.

Specified by:

controlProbe in interface IProbeController

Parameters:

event - The event that contains the information for remote control

Throws:

RemoteControlFailedException - if the connection can not be established within a set timeout.

updateProbeParameter

public void updateProbeParameter(String ip,
 int port,
 String hostname,
 String pattern,
 Map<String,List<String>> parameters)
                          throws RemoteControlFailedException

Updates the given parameters for a probe.

Parameters:

ip - Address of the monitored application.

port - Port of the TCP controller.

hostname - The name of the component which is using this IP and port.

pattern - The pattern of the method that should is monitored.

parameters - The map of parameters to be set, the key is the name and the values the values for the parameter.

Throws:

RemoteControlFailedException - if the connection can not be established within a set timeout.

activateMonitoredPattern

public void activateMonitoredPattern(String ip,
 int port,
 String hostname,
 String pattern)
                              throws RemoteControlFailedException

Activates monitoring of a method (pattern) on one monitored application via TCP.

Parameters:

ip - Address of the monitored application.

port - Port of the TCP controller.

hostname - The name of the component which is using this IP and port.

pattern - The pattern of the method that should be monitored.

Throws:

RemoteControlFailedException - if the connection can not be established within a set timeout.

activateParameterMonitoredPattern

public void activateParameterMonitoredPattern(String ip,
 int port,
 String hostname,
 String operationSignature,
 Map<String,List<String>> parameters)
                                       throws RemoteControlFailedException

Activates monitoring of a method (pattern) on one monitored application via TCP and transfers parameter.

Parameters:

ip - Address of the monitored application.

port - Port of the TCP controller.

hostname - The name of the component which is using this IP and port.

operationSignature - The pattern of the method that should be monitored.

parameters - The map of parameters to be set, the key is the name and the values the values for the parameter.

Throws:

RemoteControlFailedException - if the connection can not be established within a set timeout.

deactivateMonitoredPattern

public void deactivateMonitoredPattern(String ip,
 int port,
 String hostname,
 String pattern)
                                throws RemoteControlFailedException

Deactivates monitoring of a method (pattern) on one monitored application via TCP.

Parameters:

ip - Address of the monitored application.

port - Port of the TCP controller.

hostname - The name of the component which is using this IP and port.

pattern - The pattern of the method that should no longer be monitored.

Throws:

RemoteControlFailedException - if the connection can not be established within a set timeout.

isKnownHost

public boolean isKnownHost(String ip,
 int port)

Checks if a host is known. The searched pattern is ip:port.

Parameters:

ip - the IP of the host.

port - the used port of the TCP connections

Returns:

true, if the connections to the host was already established.
