Greetings EPICS Experts,
I am trying to dump archive data for some setpoints but am only interested in values when they change. Is there an easy way to only print out values only once they change? I was trying something like the following:
arget -s '2016-8-1 00:00:00' -e '2017-8-1 00:00:00' -c 1000 PVNAME
but this gives:
...
2016-10-19 16:58:58.343624 220.0
2016-10-19 16:58:59.367182 220.0
2016-10-19 16:58:59.877238 220.0
2016-10-19 16:59:00.399215 220.0
...
At first glance this seems like a mis-configuration of the archiver, or
noise. I certainly wouldn't want so much redundant data to be stored.
In either case, I'd suggest looking at the ADEL field of this record to
see if it should be increased.
