Class SSLCertMonitor

java.lang.Object

org.opennms.netmgt.poller.monitors.AbstractServiceMonitor

org.opennms.netmgt.poller.monitors.SSLCertMonitor

All Implemented Interfaces:

ServiceMonitor

@Distributable
public final class SSLCertMonitor
extends AbstractServiceMonitor

This class is designed to be used by the service poller framework to test the validity of an SSL certificate on a remote interface. The class implements the ServiceMonitor interface that allows it to be used along with other plug-ins by the service poller framework.

Method Detail

poll

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

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.

Poll the specified address for HTTP service availability. During the poll an attempt is made to connect on the specified port. If the connection request is successful, check the X509Certificates provided by our peer and check that our time is between the certificates start and end time. Provided that the interface's response is valid we set the service status to SERVICE_AVAILABLE and return.

Specified by:

poll in interface ServiceMonitor

Specified by:

poll in class AbstractServiceMonitor

Parameters:

svc - TODO

parameters - 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.

getSocketWrapper
