Figure 113: TCP server definition
The definition of a connection contains the following parameters.
• Define the parameter id (name) with a unique identifier of the monitored item. For
example, value Mail Server defines the connection. Avaya recommends that you choose
meaningful names name for the parameters.
• Define the parameter "port" to identify the port number. For example, use the value 25
specified the port used for SMTP servers.
• Define the parameter "state".
• Define the parameter "Listening" for monitoring TCP Servers.
A TCP Server is always up and running and in "state" of "listening" on port 25 on a local
system that runs the eFR monitoring process.
Note:
You can use the command window to verify the current servers. The command "netstat –a
–n" shows a screen similar to the one shown in the following figure. In the figure, a TCP
server, in the first column with the value TCP, listening on port 25, in the second column
ending with :25, is in the "state" of "listening".
Figure 114: Verify current servers
Note:
Important: NETSTAT assumes that TCP servers remain listening.
Important:
Only apply NETSTAT monitoring to TCP Servers that are multiple access socket servers.
When a TCP server is a single connection server, the TCP server is connected while it is
monitored by NETSTAT.
The following figure shows a more complete definition of a configuration section monitoring
the state of TCP Server that is expected to be always in state "listening". The figures illustrates
the example of an environment running a local Internet Information Server with SMTP Server
component "listening" to default port 25.
