[Feature Request] Support for InfluxDB 2.0

[lesteenman]

Is your feature request related to a problem? Please describe.
I want to use Varken with an instance of InfluxDB cloud, rather than using a locally hosted instance. This currently runs on version 2.0, and I expect that the project will want to connect to the newer version at some point in the future anyway.

Describe the solution you'd like
An option in the configuration to use the InfluxDB 2.0 API. The main difference I can see from the user side is that it uses api tokens rather than a username and password.

Describe alternatives you've considered
I've considered either hosting a 1.0 database myself, or copying the Radarr/Sonarr/Tautulli scripts from Varken and using them in my own project. However, I want to try to add support for the 2.0 client in Varken itself, if this is something you would want upstream.

[lesteenman]

An alternative option would, of course, be to use an InfluxDB instance specifically for Varken. How intended is it to use your own, general InfluxDB account vs using one specifically for Varken?

Will always take a look at PRs!

Any update regarding this feature?

[Ornias1993]

@afriberg It's an insane amount of work, so isn't going to happen any time soon (tm)
(And that can be said for all ofther projects where people are asking this too)

After doing some research it looks like we will have to rewrite the DB module to use this project instead. https://github.com/influxdata/influxdb-client-python

Hi, it would be nice if anyone could merge the pull request, so that we can start using influxdb2 with Varken.
Thanks in advance

[dirtycajunrice]

@Nicras I have not had the time to walk through this MR. I will try to make it a priority this evening.

[Nicras]

@dirtycajunrice I guess there were other things with higher priority that evening xD
It would be very cool, if you could have a look anytime soon. I had to upgrade to influxDB V2 and since then my Dashboard looks weird

@dirtycajunrice bumping since this thread is getting old -- any news on getting @Nicras's pull request merged?

Thanks a ton!
Ted

Bumping again. Is there anything keeping Nicra's pull request from being merged?

Bumping again. Is there anything keeping Nicra's pull request from being merged?

Yes, several things. We are contemplating only supporting certain modules that don't have off the shelf exporters which means a rewrite for 2.0 and parking the current version for 1.8.x only.

If you direly need 2.0 support then you can run their fork for now.

[tedtms]

@samwiseg0 thanks for the update! I'll probably do that for the time being.

As a workaround, you can create a old style db under a bucket and create user/pass for it.

Get into influx CLI and get the list of buckets. If you dont have a bucket then create one.
influx bucket list -o <your org> -t <admin token>

Use the bucket id to create a db
influx v1 dbrp create --db varken --rp varken-rp --bucket-id <bucket-id> --default -o <your org> -t <admin token>

Create a user/pass. This call will prompt you for a password
influx v1 auth create --read-bucket <bucket-id> --write-bucket <bucket-id> --username varken-user -o <your org> -t <admin token>

Then use that info on the config

[influxdb]
url = <host>
port = 8086
ssl = false
verify_ssl = false
username = varken-user
password = <password>

Tried to give this workaround a try and while it can connect fine it does some automation that crashes.

Maybe a config option to disable checking if database exists and creating a new database automatically?
