Influxdb v2 troubleshooting

Support

I am having some issues getting my influxdb v2 uploader to send data. In my message logs:

I can see that influx has started without a hitch but i am not seeing any data in influx. My uploader measurements are set to the most basic, “main_1” and “main_2” and a, “total” (the addition of the two).

Looking here for related topics, i have found the few, but sadly, i’m not finding anything really helpful. Several things i’ve checked and tried:

  1. Made sure all connection settings are working and cURL’d to create test data to test my api key.
  2. Tried different variants of the url: http://…, ip with and without the port, url with the full /api/v2 url (or however it is)
  3. Confirmed my org id, bucket, etc and again, manually ran cURL’s with these values to add test data
  4. Created new bucket and keys
  5. Restarted

My question’s are, Is there any way to debug this further? I’m not seeing this information in the docs. Does it have something to do with my measurements? I am not the most “hip” when it comes to this kind of timeseries data so i’m starting to think it’s something dumb on that side.

Thanks so much for the product. It’s really great!

offhand looks like it will start posting on Aug 1. That could be what you specified in the setup or caused by a post-dated entry in your influx dataset - possibly created with CURL.

So, i have adjusted this a few times and maybe i misunderstand. I thought this is where it started uploading from… and now i see that it is 2025. I did just adjust this before posting. It had been set to july 1 2025 yesterday when i was trying to set this up. I have just adjusted it back to this date

It appears you are maintaining your own local infuxDB2.

Can you post the curl transaction with response please?

Please add the port to the URL, then start it up. If it fails, post the message log and also a screenshot of the status display with the uploaders tab open. I’d like to see if there is a message there for influxDB2.
