org.opennms.netmgt.poller.monitors.SmtpMonitor
This class is designed to be used by the service poller framework to test the availability of the SMTP service on remote interfaces. The class implements the ServiceMonitor interface that allows it to be used along with other plug-ins by the service poller framework.

Method Detail |
public int poll(NetworkInterface iface, java.util.Map parameters, Package pkg)
Poll the specified address for SMTP service availability.
During the poll an attempt is made to connect on the specified port (by default TCP port 25). If the connection request is successful, the banner line generated by the interface is parsed and if the extracted return code indicates that we are talking to an SMTP server we continue. Next, an SMTP 'HELO' command is sent to the interface. Again the response is parsed and a return code extracted and verified. Finally, an SMTP 'QUIT' command is sent. Provided that the interface's response is valid we set the service status to SERVICE_AVAILABLE and return.
iface
- The network interface to test the service on.parameters
- The package parameters (timeout, retry, etc...) to be used for
this poll.
