The system has a special "I/O Device" driver for monitoring hosts via ping or TCP connection.
Using the Generic Ping or Generic TCP Connection Test model in the I/O Devices register, it is possible to monitor any IP or host (for equipment monitoring, for example) and configure alarms and events when the host becomes offline. It is also possible to add the status of hosts to a Synoptic Map.
•The Generic Ping driver will use the ICMP protocol to test whether the host is up and running. This method is useful for testing any type of generic IP address.
•The Generic TCP Connection Test driver will test a host TCP port (specified in the settings). The system will constantly open and close connections to this port in order to check if it is accessible. This method is useful for testing not only whether a host is reachable, but whether a service the host is providing is reachable.
The driver has 1 input port, and this port will reflect the ping status. If the port is closed, the host is working, if the port is open, the host is not accessible.
The host out of order alarm can be configured through the Alarm Input Events (Using Port 1) or also through the Communication Failure and Communication Restoration events in the "I/O Device" Registration
The image below exemplifies a simple use of the Synoptic Map to display the status of different hosts, in this case Site 1 is accessible and Site 2 is not accessible.
