Every now and then I get questions about the names of the Citrix channels in DC RUM.
These names are nothing that the decode makes up but something that we decode/discover in the traffic.
Here are a few that I found but if I get it right, you can create your own virtual channels too:
Default values for ICA chanels are presented in the table below:
|Channel Name||Description||Single Stream (XenApp 6.5)||Multi-stream (XenApp 6.5)|
|CTXCAM||Client audio mapping||0||0|
|CTXTWI||Seamless Windows screen update data (ThinWire)||0||1|
|CTXCTL||Citrix Control Virtual Channel||0*||1|
|CTXEUEM||End User Experience Monitoring||0*||1|
|CTXFLASH||Citrix Flash Redirection||0*||2|
|CTXSBR||No longer used. Previously: Citrix Browser Acceleration||0*||1|
|CTXTW||Remote Windows screen update data (ThinWire)||1||1|
|CTXVFM||Video server video (not ThinWire video)||1||1|
|CTXCCM||Client COM port mapping||2||3|
|CTXCDM||Client drive mapping||2||2|
|CTXMM||Citrix Windows Multimedia Redirection||2||2|
|CTXCM||Client management (Auto Client Update)||3||3|
|CTXCOM1||Printer mapping for non-spooling client (Thin client devices)||3||3|
|CTXCOM2||Printer mapping for non-spooling client (Thin client devices)||3||3|
|CTXCPM||Printer mapping for spooling clients||3||3|
|CTXLPT1||Printer mapping for non-spooling client (Thin client devices)||3||3|
|CTXLPT2||Printer mapping for non-spooling client (Thin client devices)||3||3|
|OEMOEM||Used by Original Equipment Manufacturers (OEMs)||3||3|
|OEMOEM2||Used by Original Equipment Manufacturers (OEMs)||3||3|
The separation of ICA traffic into multiple streams lets administrators apply Quality of Service (QoS) prioritizations to individual components of an ICA session.
Do you know any channel that can tell the login time? I remember I saw that in previous Citrix decode (12.2) but I can't find it after upgrade to 12.3 SP2.
On the other hand, any idea if DCRUM can monitor the elapse time of XenDesktop startup and application being clicked within the XenDesktop window? I suppose the answer are "NO" but want to see any workaround to achieve.
