Erroneous High/Low data

Post by chrishudson » Mon 03 Jun 2019 3:37 am

I have a weird problem with my current install of Cumulus. The high/low data in the dashboard and the today/yesterday panels do not seem to reflect the data shown in the chart screen. I'm not sure how long this has been going on.

1. This is the dashboard which shows the current time as 13:10 pm yet also shows high data from times such as 14:48, 15:07 and 16:12.

2. The today/yesterday data which also shows data from after the current time.

3. The temp graph for the last two days, which shows that what is being reported as today's high and low were actually yesterdays high and low.

I've checked the time and timezone on the Raspberry Pi, I've restarted the Pi. I'm on the verge of rebuilding my whole Cumulus install, but want to see if anyone has any ideas before I do so.

Cheers,
Chris

I think I may have solved my own problem.

I noticed that the data being written to mySQL had stopped at 30th May 13:40.

I had a look at the MXDiag files around that time and noticed an issue with network connectivity on the 30th May at about 1:05. From that point onwards Cumulus had issues writing to mySQL and that seemed to also translate into issues writing to the dayfile.txt and today.ini and yesterday.ini.

Since the reboot of the Pi, this issue seems to have been fixed [at least the mySQL writes are now working]

I'll wait and see what happens overnight when the yesterday and today files roll over to see if that fixes the issue I'm having.

For those that are interested, I've attached the MXDiag file.

Cheers,
Chris

Yep, that was the issue. Everything is now working as expected.
