InfluxDB Metrics provider not working in v3.0

[mira-miracoli]

Welcome!

• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've searched similar issues on the Traefik community forum and didn't find any.

What did you do?

I am running traefik as docker swarm service, and before I added these following lines to my docker swarm configuration, everything worked fine:

      - --metrics.influxdb=true
      - --metrics.influxdb.pushinterval=10s
      - --metrics.influxdb.address={{ influxdb.url }}
      - --metrics.influxdb.protocol=http
      - --metrics.influxdb.database={{ influxdb.node.database }}
      - --metrics.influxdb.username={{ influxdb.node.username }}
      - --metrics.influxdb.password={{ influxdb.node.password }}

I am deploying with ansible, in case you are wondering about the {{ variables }}.

What did you see instead?

When I check the service with docker service inspect traefik I see the following:

traefik.1.semllbuvwmso@XXXXXXX | {"level":"error","error":"command traefik error: failed to decode configuration from flags: field not found, node: influxdb","time":"2024-03-05T14:03:55Z","message":"Command error"}

What version of Traefik are you using?

v3.0

What is your environment & configuration?

It may look a bit strange because traefik is deployed as docker swarm service by my own ansible role

Hello @mira-miracoli,

Thanks for your interest in Traefik!

Indeed, InfluxDB (1) support has been dropped in v3, please check out the dedicated section of our migration guide.
However, InfluxDB2 is supported.

I'm closing this issue as a question accordingly.

[mira-miracoli]

Thanks, then it would be nice to mark that accordingly, because I found this page, and nothing on it stated, that it was dropped in v3. would be nice to have a bar or something that shows the traefik version I am looking at in the docs

Hello @mira-miracoli,

I think "emphasize the version selector" in issue #9549 is tracking what you are suggesting, and it is definitively something we want to improve.

Until v3 is GA, the latest version is still v2.x, and the documentation version selector (which is at the bottom of the left-side menu) selects the latest version by default.
