Monitoring FTP Server via an FTP Probe
======================================

This sample is very similar to the Ping Probe and Port Probe samples. 
Thus, we describe it briefly, only.

FTP Probe is used to make a connection to the FTP server. Then it receives 
the response from FTP server and sends the QUIT command to terminate the 
connection. The connection status is saved in the property **ftpstatus** and the 
response in the property **ftprespmsg**.

In our sample, we probe a FTP server, which typically listens to port 21 (the 
default port for FTP). We send an email alert if the FTP probe cannot connect 
successfully to the FTP server.

Because this sample is so close to the previous ones, we do not create a new 
rule set specifically for email alerting. Please view "Ping Probe" for it. This 
is a good sample of rule set re-use. If necessary rename the rule set in such 
a case. For simplicity reasons, we have not done this here.

Therefore, we begin by creating the new service, done by right-clicking 
"Services":

After doing so, select the newly created service in the tree view to look at 
its properties. Be sure to bind it to the "Send Email" rule set as seen below:

Save the configuration and restart the service. From now on, the following mail 
alert is generated when the port cannot be connected to:


.. code-block:: none

  Event message:
  Facility: 16
  Priority: 6
  Source: 192.168.1.1

  Message:
  FTPProbe status="fail" target="192.168.1.1" port="21" 
  netstate="10061" message="Couldn't connect to host"
