7days/1month chart: no data displayed about temperature-machine HOT 15 OPEN

Is there anything in the log? Is it just after you started up? The charts are regenerated periodically, so the first time you start up, the charts will be empty. Refresh and it should come back.

I know after start is available after 1 min. But yesterday not work all day. I will check the log and I post here.
Thank you.

I had the same problem but found that if I refreshed the page more than enough times, it eventually came back.

has it come back @andrei2186 ?

from temperature-machine.

Yes. All are ok now.

The problem come back.2 hours ago.

Is there anything in the log? how about the browser console (in Chrome hit cmd + alt + i)?

from temperature-machine.

I think the problem was generated from raspberry forced shutdown. Where are the logs?

Logs are in .temperature under your home folder.

cat ~/.temperature/temperature-machine.log

FYI, charts are regenerated as per the following schedule. I have no clue at the moment why that might fail but will start by reviewing the logging (as I see nothing at present in the logs). Worse case, refresh the page according to the schedule and see if they appear (at least until we can fix it)

• Every 90 seconds for the last 24 hour chart
• Every 12 hours for the last 7 days chart
• Every 24 hours for the last 30 days chart

from temperature-machine.

Just to add that I see this issue a lot. The 24-hour graph is usually fine, the 7-day graph is empty most of the time, and the 1-month... I think I've only seen it display some data once or twice.

from temperature-machine.

I'm seeing the same, and from the file timestamp I can see the charts are all re-generated when the service restarts (or the host is rebooted), but it seems that this initial create uses an empty dataset, as it's not until the subsequent scheduled run that the graphs get properly rendered - I can't yet see where/why this is happening in the code.

Thanks for the comment, I suspect a race condition in the task startup stuff around here:

but it's just a guess at this point.

A breakpoint (assuming you can reproduce) in Graph.scala should at least say if it's because of an empty data set. I had (vainly) assumed it was a bug in the underlying RRD before.
