Graphs not drawing correctly after restart under certain circumstances

Topics about the Beta trials up to Build 3043, the last build by Cumulus's founder Steve Loft. It was by this time way out of Beta but Steve wanted to keep it that way until he made a decision on his and Cumulus's future.

Graphs not drawing correctly after restart under certain circumstances

Post by freddie »

I have noticed this behaviour before but thought it was a one-off (or maybe something I had done).

If you stop and start MX and there is a change of month in the defined graph data series interval (mine is set to 72 hours) then the data from the last record before MX was stopped until the first record after the turn of the month (mine is set to 0900) does not get plotted. The data is present in the monthly data files, but is not present in the JSON responses supplied to the graph.

Attached are a screenshot and the temperature JSON file (saved with a .txt extension to get round upload permissions).

Note that this behaviour occurs in the interface as well. It looks as if it is a defect with the populating of the JSON files from archive data when the above conditions are met.

Can you clarify - you stopped Cumulus on Saturday at about 1435, and restarted it today (or some time after the start of the month)? If you restart it now, does it correctly draw the graphs?

Could you also please zip up the MXdiags folder and attach it, together with your April log file.

Apologies - I have checked the diags files and there was an error message about a line in the April data file. I checked the data file, and there was a blank line in there. Removing the blank line has cleared the problem.

This must've been what happened the previous time too, so I apologise for jumping the gun and wasting your time - and will remember to check next time!
