3.6. SOE Collection Mode
The Communications Interface has a large buffer of events. It is possible to gather this buffer first until
the collector has caught up with current events, but this can take a long time. Therefore there is an
option under the Mode menu for choosing how much of this buffer is collected.
From Now Ignore all buffered events and only collect real time events
All Buffered Gather the entire buffer first before waiting for real time events
25% of Buffer Gather the last quarter of the buffer first
50% if Buffer Gather the last half of the buffer first
75% of Buffer Gather the last three-quarters of the buffer first
3.7. SOE Start Collecting
Once the procedures detailed above have been completed, the user may start the collection process.
If any buffered events have been selected in 3.6, events currently buffered in the Trusted
TM TMR
Communications Interface module will be collected and added to the SOE display. Once the SOE
Collector has retrieved all buffered events, it will regularly poll for new events. All new events will be
added to the display.
To initiate the collection of SOE data, the user must select the ‘Start Collecting’ option from the ‘File’
menu
The collection of SOE data is stopped by selecting the ‘Stop Collecting’ option which is also in the ‘File’
menu.
The initial collection process can take a long time before events are displayed on the screen. The
program is parsing through events gathered before the end of the log, and it will display log entries
once the date and time of events is past the end of the current log.
If the SOE or PH collector is running when the system application is compiled in the Toolset, then the
dictionary files appli.tst, appli.dco and appli.dlo will be locked by the collector and the compilation will
fail. If it is necessary to keep the collector running during a long compilation, copy the files to another
location. Note that if the dictionary is changed in a way that affects event variables, the SOE collector
will need to be stopped to load the new symbol files.
