• system.daemon for the notification daemon.
• criticality.daemon for the prioritization daemon.

Returns:

the type of the daemon

getStartTime

Date getStartTime()

Returns the time of the last daemon start.

Returns:

the start time

getLastExecutionTime

Date getLastExecutionTime()

Returns the time of the last daemon execution.

Returns:

the last execution time

isRunning

boolean isRunning()

Returns whether the daemon is currently up and running.

Returns:

true, if the daemon is running, otherwise false This flag is determined heuristically based on start time, last execution time, daemon periodicity, current time and acknowledgement state.

getAcknowledgementState

Returns the acknowledgement state of the daemon query.

Returns:

acknowledgement state or null if the daemon operation was done without acknowledgement

getDaemonExecutionState

DaemonExecutionState getDaemonExecutionState()

Returns the execution state of the daemon.

Returns:

execution state

getExecutionLog

org.eclipse.stardust.engine.core.runtime.beans.DaemonExecutionLog getExecutionLog()

Return the execution log of the last daeon execution
