Graphs went blank....

Post by tomcatuk » Sat 03 Aug 2013 11:48 am

I updated a program on my computer, but ended up with an error a missing dll file was advised to update Visual C++ Runtime files which I did and the program works....

When running cumulus I noticed all my graphs had gone blank, and I've no idea why, then it would not start, and the graphs are only showing info from 4am this morning, I only noticed the problem typically 30mins before having to go to work yesterday at 3pm and thought it was all ok, came in this morning in the early hours and it had lost contact with the computer, anyway fired it up again and now seems to be working.

I had copied the backup files over from yesterday morning but was unsure if I had to do the same with the daily ones hoping that this had cured it....

It's probably nothing to do with the graphs themselves, it will be missing data. It was probably unable to download data for a period.

If you copied some but not all of the backup files, that's likely to make things worse; you have to copy them all from a known good start point (i.e. before you started having problems with your computer), and then start Cumulus.

If you zip up the diags folder and attach it, I'll see if I can see anything; but having copied some of the backup files it may be difficult to work out what was going on.

Hi Steve, yes sorry I never realised about the daily files, as they all have a daily date stamp for 00:00and the others are dated differently so never copied those over... is there a procedure for copying them over?
Diags included.

Sorry, I misunderstood. The daily backup files are just an alternative to the startup backup files. They exist so you always have a recent backup if you don't restart Cumulus very often. You choose either a daily backup or a startup backup and copy all of the files from the folder into the data folder.

Contact was lost to the station just after midnight:

03/08/2013 00:02:19.541 : VP2: LoadCurrentVantageData_V, error = -32701

03/08/2013 00:04:00.838 : *** Data input appears to have stopped, restarting

You have 'restart if data stops' set, so it restarted. It was still unable to talk to the station after the restart (not really surprising), and it looks like you closed it and restarted it at about 0340. It successfully downloaded all of the missing data from midnight and carried on. I'd have expected it to do this anyway without any intervention. I can't see any problems other than the initial communication problem.

Hi Steve, this is weird... just restarted Cumulus again and seems to take forever to download data and my graph files have been wiped again so not sure what's going on.... I'll just leave it running and see what happens today.

You just stopped it and started it again immediately, without doing anything else? This can sometimes provoke the station into sending the entire contents of the logger, which causes a slow startup, but Cumulus copes with this.

If you attach the diags files again, I'll take a look. Can you also attach your August log file, please.

The slow startup was because the station sent the entire contents of the logger.

The graphs problem is because you have some spurious entries at the start of your August log file:

The most likely cause is that the clock on your PC was wrong at some point in the past (it could have happened at any time, not necessarily recently). You need to stop Cumulus and remove those first six lines from the file.
