connection. Nortel 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 124
Verify current servers
Note: Important: NETSTAT assumes that TCP servers remain
listening.
ATTENTION
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.
