When the event builder is used with the DAQ Manager it must be started differently. The event builder must be started from within the manager and should be run in persistent mode. The event buider should be started from the BOOT transition of the manager. In general, since the event builder is a pipeline, you will need a script to run the event bulder. The form of this script should be:
Example 8-1. Script To Start The EventBuilder in the Manager
#!/bin/bash
TCLLIBPATH=$DAQTCLLIBS $DAQBIN/EVBRest | \
$DAQBIN/glom [glom options] | \
$DAQBIN/stdintoring [evb ring]
There are a few items in this sample script you'll need to fill in depending
on the needs of your experiment. For [glom options]
you must fill in at least a --dt value to set the coincidence
window in which events are built. You may also wish to set the
--sourceid to define the output source id and
--timestamp-policy to determine how output event timestamps
are computed.
For [evb ring] you will need to supply the name of a ring buffer into which the data will be placed for distribution.
When the Event Builder is used in this manner, there is no inherent user interface. You can use the $DAQBIN/EVBMonitor program to display the graphical statistics. This program is descsribed in EVBMonitor
