A count finds the number of unread events in the event log. You can specify the event types to return,
or return the count for all events.
This command reports the number of events that have occurred since the command was last sent or
since the event log was last cleared.
Events are read automatically when
localnode.showevents
is enabled. You can also read them
individually with
eventlog.next()
.
Example
print(eventlog.getcount(eventlog.SEV_INFO))
Displays the present number of unread
information messages in the instrument
event log.
If there are three information messages in
the event log, output is:
3
