Timing Messages: How-To Snoop the Timing System
FEC for FESA class is now scuxl0143.
This is a first simple solution to view what is going on at the timing system. It uses a FESA class on a SCU which subscribes to all messages broadcasted via the timing network. The message data is written to a FESA property and can be retrieved via the Controls MiddleWare (CMW). Please use this tool for viewing what is going on in the timing system.
Remark: Front-Ends provide a set of command line tools
can also be used locally on a specific front-end (SCU).
Our colleagues from the Beam Instrumentation group have developed a small Java GUI
On one of the
nodes, simply start the "Java Snoop GUI" and have fun.
[user@asl123 ~]$ /common/usr/lobi/bin/wrsnoop
The FESA class must run on the SCU. If not, the FESA class must be instantiated. Example (November 2014):
[user@scuxl0019 /]# cd /opt/fesa/local/scripts
[user@scuxl0019 scripts]# ./start_WREventListDU_M.sh &
FESA Class and Deploy Unit
=> WREventList & WREventListDU
