Catching up with missing data with the VantageVue logger
Posted: Thu 28 Apr 2016 12:27 pm
I have a Davis VantageVue running with Cumulus, and the logger interval is set to 10 minutes on both the VantageVue and in Cumulus.
Today my PC's power supply stopped working, so it was down for about 5 hours.
When I started Cumulus up again, I expected it would read the archive data from the logger and catch up, but when I looked at the graphs, it seemed to be missing data. Also the "Archive records read" count at the bottom of the screen was 0.
So I checked the "apr16log.txt" file, and sure enough there's a 5 hour gap from 10:30 to 15:00
I checked the diags folder, and found where I think it should have been loading the archive data:
That looks like it read the data, but not sure what happened. I also tried a test where I shut down Cumulus just before the 10 minute mark and started it back up just after. No archive records read and a missing data record in "apr16log.txt" file.
Also, I found other areas in the log file where I shut Cumulus down and restarted it, where there seems to be more information in the log when it's reading the logger that was missing earlier.
Any ideas?
I did upgrade from Windows 7 to Windows 10 last year, so not sure if that could have anything to do with it.
