Class MarkFailEventDetector

java.lang.Object
  network.detectors.EventDetector
      network.detectors.MarkFailEventDetector

All Implemented Interfaces:

java.lang.Runnable, java.io.Serializable

public class MarkFailEventDetector

extends EventDetector

Looks for the MARK message in the syslog file. If the MARK message is not seen in a specified amount of time, a MarkFailEvent will be created This is used to detect if the syslog daemon is down

MarkFailEventDetector

public MarkFailEventDetector(ConfigObject configObj)

Creates a MarkFailEventDetector with the default mark time specified in AdminClient The mark time is the amount of time the detector will wait for a mark event before creating a MarkFailEvent

MarkFailEventDetector

public MarkFailEventDetector(long markTime,
                             ConfigObject configObj)

Creates a MarkFailEventDetector with the specified mark time specified in AdminClient

Parameters:

markTime - The amount of time the detector will wait for a mark event before creating a MarkFailEvent

MarkFailEventDetector

public MarkFailEventDetector(java.lang.String markTime,
                             ConfigObject configObj)

Creates a MarkFailEventDetector with the specified mark time specified in AdminClient

Parameters:

markTime - The amount of time the detector will wait for a mark event before creating a MarkFailEvent. Must be parseable into a long

Method Detail

getParamList

public static java.lang.String[] getParamList()

Returns array of strings containing all the parameters that can be used as input to modify this detector. Each entry in the array corresponds to one parameter with structure " : ".

Returns:

parameterList, an array of Strings indicating parameters and their types

translateParameters

public static java.lang.Object[] translateParameters(java.lang.String[] inputarray)
                                              throws java.lang.Exception

This function takes an array of strings from GUI which contains input and converts them to array of objects and returns.

Parameters:

inputarray - an array of strings that contains user inputs.

Returns:

objArray an array of objects converted from the array of strings got from user.

Throws:

java.lang.Exception

modifyDetector

public void modifyDetector(java.lang.Object[] object)
                    throws java.lang.Exception

Allows modification of detector configuration by passing a Long object of milliseconds for the new time out.

Overrides:

modifyDetector in class EventDetector

Parameters:

object - an array of Objects with a Long object as the only parameter

Returns:

Throws:

java.lang.Exception

getGeneratingEventClassName

public java.lang.String getGeneratingEventClassName()

Returns the name of the event that this detector triggers

Specified by:

getGeneratingEventClassName in class EventDetector

Returns:

A String containing the name of the event this detector triggers

generateEvent

public java.util.Vector generateEvent(Event triggeredEvent)

Receives either a TimerEvent or SyslogEvent. If triggeredEvent is an instance of TimerEvent, this will check to see if the syslog has received a mark message in the amount of time specified in the constructor. If triggeredEvent is an instance of SyslogEvent, this will check to see if a mark message has been written to the syslog and update the time counter.

Specified by:

generateEvent in class EventDetector

Parameters:

triggeredEvent - The event triggering this detector

Returns:

A vector of events this detector creates
