Hi, I’m a newbie, moving from InfluxDb 1.8 to 2.x. So I have to migrate my continuous queries to tasks. Now I have made up a Flux Task that nicely downsamples my data to hourly or daily level, and writes this to the appropriate bucket. This works all fine when I start the task by pressing the “Ru…

Yes, now after choosing a range of 2h, when doing the aggregation you will get the last values from the last two hours, being able to calculate te difference between these. Try that out and let me know if the result is what you expected.

And this is the detail-info if I click the “View Logs” button from an automated run that didn’t result in data written to the bucket (sorry this is a long line): 2022-03-22 22:01:00 Started task from script: "option task = {\n name: \"SolarHourly\",\n every: 1h,\n offset: 1m,\n}\n\ndata = …

I have same issue. No error on log, manually launched a script it writes to the bucket but not when scheduled. Did you get some success?

Reply, not really. I did however seem to find out that it is related to the use of the difference() function. If I comment that out in the example above, it all does write the data again. So question is, why that is? Or, how I can rewrite this query not using difference()? The goal is to calcula…

Yes, seems also to me issues is with difference. I use same function and… It doesnt write to new bucket. It does write only manually launched from copy and paste inside window editor on source bucket. We are on same boat: I can Imagine a bug…

Interesting! Wonder if more people have the same issue. In the mean time, would you know an alternative way to solve this?

I want know an alternative way. But I don’t have it. We can only hope in moderators / staff.

@Anaisdg can you indeed verify if the difference() function has this weird behavior, when started automatically with a task? Thanks!

@MarcoB I opened an issue on github project. I did read on somewhere that an issue there probably will prioritize the request (or… move to their attention). If you think, you can upvote it there: Task with difference doesn't write to destination bucket · Issue #23231 · influxdata/influxdb · GitHub

Hello, I am quite new to Influx so I might be away from the solution, but I am going to try anyways. So, from what I understand, you are trying to create a task that retrieves the hourly kWh power of your solar panels by calculating the difference with respect with the previous hour, isn’t this ri…

Hi, That’s a good point! I actually also was thinking in that direction. It explains why this works manually, as then the task is triggered outside the full-hour, so the task finds 2 results. Indeed the idea is to calculate the hourly Kwh usage by using the difference between the 2 last counter v…
