Unable to connect to Influxdb 2.0

ROODAY commented 3 years ago

Description

I followed the docs for connecting to influx but whenever I try to run glances --export influxdb I get Cannot connect to InfluxDB database 'glances' (401: {"code":"unauthorized","message":"Unauthorized"}). I had similar authentication issues connecting Influxdb to Grafana, and was only able to fix it by using the Flux connection options that used Organization and Bucket instead of username and database. Is there a way to use similar connection options for glances? This is my current conf file:

[influxdb]
host=localhost
port=8086
protocol=http
user=ROODAY
password=**************
db=glances

Versions

Glances & psutil (glances -V): Glances v3.1.5 with PsUtil v5.8.0

InfluxDB v2 requires using authentication token, organization, and bucket arguments. The influxdb API integration within glances will need an update to be able to use it first.

Quick analyse concerning the implementation of the InfluxDB 2 API:

the "old" client (https://github.com/influxdata/influxdb-python) is only compatible with InfluxDB < 1.8 (before the Flux implementation)
the "new" client (https://github.com/influxdata/influxdb-client-python) can be used for InfluxDB 1.8+ or 2.x. It is only compatible with Python 3.6 or higher.
the "new" client need the following information: bucket name, token, org (see this post to know how to get the information from an existing InfluxDB 2.x server)

Questions to be taken into account before the development:

keep the double compatibility API v1 / API v2 ? if yes how to deal with the configuration file (one section ? two section ?)
Docker environment are available for the new InfluxDB 2 version ==> https://docs.influxdata.com/influxdb/v2.0/get-started/

@paularmstrong Implementation for the new exporter (called influxdb2) done in the develop branch.

Read the doc ==> https://github.com/nicolargo/glances/blob/develop/docs/gw/influxdb.rst#influxdb-v2-from-influxdb-v18xflux-and-influxdb-v2x

Note: you need to install the https://pypi.org/project/influxdb-client/ InfluxDB client.

Tested with InfluxDB 2.0.3.

Please can you test it on your side.
