Citrix Monitor

 Keywords: Citrix Monitor Metaframe XP

Question:

I am looking at writing a script that would monitor a citrix server running Metaframe XP. All I am looking at to do (for now) is to open up a session to the server; confirm that I connected and then disconnect. If unable to connect then some kind of notification would be sent out.
Looking through the Terminal Services Extender, I don't see a function that actually initiates a session.

Is the above even possible with Winbatch?

Answer:

The terminal server extender is used for making your scripts aware of the terminal services environment on a terminal server system. It does not have any Terminal Server/Citrix client functionality in it.

Suggestions:

You could verify that you can telnet to port 1494, it should return an "ICA" if the server is functioning. I believe that you could also "ping" the server on that port to verify that it is listening. Using telnet to connect to TCP port #1494 is probably the best way to verify connectivity to a Citrix server that is set up to use ICA. Basically, use the Winsock extender to open a TCP connection to port 1494 and verify that you can connect that you do get the text "ICA" in the string of characters that you will receive if things are working OK. There will be some other non-printable/non-displayable characters in the string, to, but "ICA" will be in the string.
I basically took this out of the help file, but it is a good example of how to do it. Just replace mycitrixserver with your server.
```
AddExtender("wwwsk34i.dll")
socket = sOpen ()
if socket != @FALSE
status=sConnect (socket, "mycitrixserver", "1494")
if status == @TRUE
; msg=sRecvLine(socket,256)
Message("Citrix Alive","Server is alive")
else
err=wxGetLastErr()
msg=wxGetErrDesc(err)
Message("Winsock Error A %err%",msg)
endif
sClose(socket)
else
err=wxGetLastErr()
msg=wxGetErrDesc(err)
Message("Winsock Error B %err%",msg)
endif
exit 
```
You could also verify that the IMA service is up and running. See the wntSvcStatus function in the win32 Network Extender.
You might be able to script the connection to the server. You will just have to send the keys to the server because I don't believe that you can control the windows within the session.
Another thing to consider might be to look at the ActiveX control version of the Citrix client that is used to allow the Citrix client to be invoked inside of a web browser window frame. Maybe you could use the OLE client features in WinBatch to drive the Citrix client ActiveX control.
