Issues with Glances exporting to InfluxDB2 on Docker Compose

[felipebraz]

Hi, I'm trying to connect Glances to InfluxDB2 to export data through docker compose and I first tried:

services: glances: container_name: glances environment: - GLANCES_OPT=-q --export influxdb2 --time 10 - INFLUXDB_HOST=192.168.1.2 - INFLUXDB_PORT=8060 - INFLUXDB_PROTOCOL=http - INFLUXDB_TOKEN=xxxxxxxxxxxxxxxxxxxxxxxxx - INFLUXDB_ORG=xxxxxxxxxxxxxxxxxxxxxxx - INFLUXDB_BUCKET=dataserverGlances image: nicolargo/glances:latest-full network_mode: bridge pid: host privileged: True restart: unless-stopped volumes: - /var/run/docker.sock:/var/run/docker.sock:ro

In this case the compose logs has nothing, it seems the app is not running.

Then I tried the dev image:

services: glances: container_name: glances environment: - GLANCES_OPT=-q --export influxdb2 --time 10 - INFLUXDB_HOST=192.168.1.2 - INFLUXDB_PORT=8060 - INFLUXDB_PROTOCOL=http - INFLUXDB_TOKEN=xxxxxxxxxxxxxxxxxxxxxxxxx - INFLUXDB_ORG=xxxxxxxxxxxxxxxxxxxxxxx - INFLUXDB_BUCKET=dataserverGlances image: nicolargo/glances:dev network_mode: bridge pid: host privileged: True restart: unless-stopped volumes: - /var/run/docker.sock:/var/run/docker.sock:ro

In this second try I have some activity in log but at the same time an error:

glances | 2026-04-01 04:47:50,539 -- INFO -- Start Glances 4.5.4_dev1 glances | 2026-04-01 04:47:50,539 -- INFO -- CPython 3.12.12 (/venv/bin/python3.12) and psutil 7.2.2 detected glances | 2026-04-01 04:47:50,544 -- INFO -- Read configuration file '/etc/glances/glances.conf' glances | 2026-04-01 04:47:50,760 -- INFO -- Start GlancesStandalone mode glances | 2026-04-01 04:47:51,156 -- INFO -- Followings processes stats will not be displayed: cpu_num glances | 2026-04-01 04:47:51,339 -- INFO -- Connected to InfluxDB server version None (HTTPConnection(host='localhost', port=8086): Failed to establish a new connection: [Errno 111] Connection refused) glances | 2026-04-01 04:47:51,675 -- INFO -- Quiet mode is ON, nothing will be displayed

It seems the app is almost working now, it is trying to export but it is ignoring the environment variables.

There is another "catch", I'm running the container on a TrueNAS server, so accessing the volume (and config file) may be a little complicated, so I'm avoiding map it on the volumes.

What am I doing wrong?

It looks like Glances is ignoring those variables because the InfluxDB2 exporter expects a specific prefix to map them correctly. When the exporter can't find its config, it defaults to localhost:8086, which is exactly what you're seeing in your logs.

Since you're avoiding a glances.conf file on TrueNAS, you need to use the GLANCES_INFLUXDB2_ prefix for your environment variables so the internal config parser knows they belong to that export module.

The fix is to update your environment section like this:

environment:
  - GLANCES_OPT=-q --export influxdb2 --time 10
  - GLANCES_INFLUXDB2_HOST=192.168.1.2
  - GLANCES_INFLUXDB2_PORT=8060
  - GLANCES_INFLUXDB2_PROTOCOL=http
  - GLANCES_INFLUXDB2_TOKEN=xxxxxxxxxxxxxxxxxxxxxxxxx
  - GLANCES_INFLUXDB2_ORG=xxxxxxxxxxxxxxxxxxxxxxx
  - GLANCES_INFLUXDB2_BUCKET=dataserverGlances

I believe latest-full was failing silently because the process was likely crashing on the connection error before it could flush logs to stdout. Using the prefixed vars should fix it for both images. lmk if that works!

I'm having the exact same issue on Truenas Scale 25.10.3.1 when trying to use the influx2 exporter option. The App even doesn't come up. Am i missing something? Removing all influx related options glances just works fine.

services:
  glances:
    container_name: glances
    environment:
      - GLANCES_OPT=-w --port 10180 --export influxdb2
      - GLANCES_INFLUXDB2_HOST=xxx.xxx.xxx.xxx
      - GLANCES_INFLUXDB2_PORT=8086
      - GLANCES_INFLUXDB2_PROTOCOL=http
      - GLANCES_INFLUXDB2_TOKEN=xxxxxx
      - GLANCES_INFLUXDB2_ORG=xxxxxx
      - GLANCES_INFLUXDB2_BUCKET=xxxxxx
    image: nicolargo/glances:latest-full
    network_mode: host
    pid: host
    privileged: True
    restart: unless-stopped
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /etc/localtime:/etc/localtime:ro
version: '3.8'
