Qfarm and QProcess the basics

Written by Hans Straat, Wednesday, 13 September 2006

In Citrix metaframe Presentation server you get a lot of goodies to use with the command prompt. Two of these goodies are explained in this tiny howto. The basics of Qfarm and Qprocess.

QPROCESS options

*
processid
username
sessionname
programname
/server:servername

These options give you a load of information which you can pipe to a txt file which is not possible with the task manager of CMC.

If you use for example qprocess * > c:\temp\processes.txt then all information will be written to the file processes.txt. A simular output like this will form then.

USERNAME              SESSIONNAME         ID    PID IMAGE
(unknown)             console              0      0
system                console              0      4 system
system                console              0    628 smss.exe
system                console              0    700 csrss.exe
system                console              0    732 winlogon.exe
system                console              0    784 services.exe
system                console              0    808 lsass.exe
system                console              0    964 svchost.exe
network service       console              0   1096 svchost.exe
network service       console              0   1180 svchost.exe
local service         console              0   1236 svchost.exe
system                console              0   1248 svchost.exe
system                console              0   1544 spoolsv.exe
network service       console              0   1572 msdtc.exe
system                console              0   1700 vcagent.exe
ctx_smauser           console              0   1736 cpsvc.exe

If you however want to see what one user is doing and log it you can then see where the user is logged on to and use qprocess username > c:\username.txt to capture the outcome.

see example

We did a output request on qprocess dummy and qprocess /id:21 which is the id that user dummy works on.

USERNAME              SESSIONNAME         ID    PID IMAGE
dummy                 ica-tcp#53          21 14532 ssonsvr.exe
dummy                 ica-tcp#53          21 42272 wfshell.exe
dummy                 ica-tcp#53          21 14896 proquota.exe
dummy                 ica-tcp#53          21 15936 mstsc.exe
USERNAME              SESSIONNAME         ID    PID IMAGE
system                ica-tcp#53          21 41204 csrss.exe
system                ica-tcp#53          21 13392 winlogon.exe
dummy                 ica-tcp#53          21 14532 ssonsvr.exe
dummy                 ica-tcp#53          21 42272 wfshell.exe
dummy                 ica-tcp#53          21 14896 proquota.exe
dummy                 ica-tcp#53          21 15936 mstsc.exe

Now you see you also get the pid numbers the system accounts works on and the dummy account.

You can do lot's more with qprocess by simply trying it out.

QFARM options

With Qfarm you get another range of command prompt goodies that are handy. You can easely query from a command prompt if a server is offline or online etc.

Qfarm parameters

TCP
IPX
Netbios
Addr
App
Disc
Load
Offline
Online
Servers
Process
Zone
Zoneapp
Zoneload
Continue

Let's take a look at the addr (address)

If you query it like Qfarm /addr servername you get simular output

M:\>qfarm /addr servername

Server Transport Network Address
-------------------- --------- --------------------
SERVERNAME TCP/IP 192.168.2.2

You can also use Qfarm /load which shows you the current load on a server. It's a static point however so gives you only a snapshot of the load of that current time on the farm.

If you want to see what disconected sessions you have you use Qfarm /disc which shows you the disconnected sessions.

In following example you see all disconnected sessions without having to look for them in the CMC :)

M:\>qfarm /disc

Client Name               Application Name                         Transport
------------------------- ---------------------------------------- ---------
WI_syjA9IMjz5rZaxkI       Desktop                              TCP/IP
WI_v_4ZkEDbOCNbZlvL       Desktop                               TCP/IP
farm-userame            Desktop                               TCP/IP
farm-username           Desktop                       TCP/IP

with Qfarm /online you can easely see what server(s) are online and with qfarm /offline the oposite.

M:\>qfarm /online

Server Name          Zone Name
-------------------- ---------------
SERVERNAME            192.168.2.2 D
SERVERNAME            192.168.2.3
SERVERNAME            192.168.2.4
SERVERNAME            192.168.2.5

You see a D behind the first server which means it's the Data Collector. Also handy if you have multiple zones in your citrix environment you see right away which server is the data collector.

Well for all other options use them as you see fit. There are more command prompt options which will be explained in another howto sometime.
