isPokeOutputEnabled

public boolean isPokeOutputEnabled()

Returns true if the poke command should generate output. The default implementation returns true. Subclasses may disable poke output by returning false. If output is enabled, the poke command prints detailed information about whether or not the process is running or needs to be restarted, and if a restart was necessary, whether the restart was successful. This information is very useful to capture in a log for diagnostic purposes.

Returns:

true if poke output should be enabled, false otherwise

                        java.lang.String msg)
