@1192410 It definitely seems that the _value column is a string (instead of an integer). I read through this post and the conclusion seemed to be to re-populate the data correctly.
The error you received references a column called “data_size”, but I do not see that in your original output:
How are these values getting sent in? Are the commas in _value there, or being added by InfluxDB? I believe InfluxDB is seeing those values as strings.
Can you go to the system where the data is being scraped and sent into Influx and check your settings there?
