The sesstail utility is similar to the qtail utility, except that it is designed to monitor 
the logfiles of the dsm process for session-related information. Examples of session-
related information include session set up and tear-down activity. 

You can use the sesstail utility to monitor the logfiles of the dsm process for session-
related activity in real time or to search for session-related activity in existing dsm 
logfiles. 

Note:  By searching for session-related activity in existing dsm logfiles, you can 
troubleshoot VOD problems that have already occurred. 

 

Follow these instructions to run the sesstail utility. 
1  If necessary, open an xterm window on the DNCS.



3. 

 

To review existing dsm logfiles for session-related activity, go to step 5. 

3  To monitor the dsm logfiles for session-related activity in real time, type sesstail 

and then press Enter. The sesstail utility begins monitoring the dsm logfiles for 
session-related activity.
