In your log file, I don’t see any error, therefore the data are being written as expected.
I’ve got few questions:
- How many points are you sending in 500ms?
- What’s your configured precision? (I don’t see it so by default it’s seconds)
- Are the gathered data all equal (except for timestamp)?
- Do you have the timestamp in the messages themselves? if yes can you use the timestamp coming from the data itself?
if you don’t provide a timestamp, telegraf will generate one by itself, equal for all points.
If you have points of the same series, with the same timestamp you will get an update, not an insert, I gave some suggestions about it in this post
Once you go through the questions and a bunch of replies in the linked post you should be able to understand what’s going on by yourself.
Le t me know if you need more info
