poll

public PollStatus poll(MonitoredService svc,
                       Map<String,Object> map)

This method is the heart of the plug-in monitor. Each time an interface requires a check to be performed as defined by the scheduler the poll method is invoked. The poll is passed the interface to check

By default when the status transition from up to down or vice versa the framework will generate an event. Additionally, if the polling interval changes due to an extended unavailability, the framework will generate an additional down event. The plug-in can suppress the generation of the default events by setting the suppress event bit in the returned integer.

Specified by:

poll in interface ServiceMonitor

Specified by:

poll in class AbstractServiceMonitor

Parameters:

svc - TODO

map - The package parameters (timeout, retry, etc...) to be used for this poll.

Returns:

The availability of the interface and if a transition event should be suppressed.
