Architecture
InfluxDB will run on in a Docker container.
This setup assumes that a Docker host is accessible on the LAN. In this example, the local domain is vnet and the host name is docker4.
Therefore, the Docker host FQDN is docker4.vnet
InfluxDB Container
Your USERNAME, PASSWORD, and ORG will vary.
I made my org the same as my local networking domain, but that is not a requirement.
docker run -d \
-p 8086:8086 \
--mount type=volume,source=influx-data,target=/var/lib/influxdb2 \
--mount type=volume,source=influx-conf,target=/etc/influxdb2 \
--name idb \
-e DOCKER_INFLUXDB_INIT_MODE=setup \
-e DOCKER_INFLUXDB_INIT_USERNAME=vince \
-e DOCKER_INFLUXDB_INIT_PASSWORD=secret-password \
-e DOCKER_INFLUXDB_INIT_ORG=vnet \
-e DOCKER_INFLUXDB_INIT_BUCKET=proxmox \Connect Proxmox to InfluxDB 2
As of Proxmox 6.4, it is possible to use the version 2 API of Influx.
Before that, Proxmox would connect to Influx 1.x, but it was sending graphite line protocol over UDP (yuck). Now it connects via TCP/HTTP to the Influx API.
Get the Token
Log into the Influx web user interface, and copy the token for the user.
Click the token name to reveal the token.
http://docker4.vnet:8086/
There is probably a command-line way to do that, but I don’t know it.
Configure Proxmox Metric Server
The name can be whatever you want.
Paste the token from the last step into the “Token” field in the Proxmox UI.
Confirm Proxmox is Saving to InfluxDB
Navigate back to the InfluxDB web UI, and confirm that data is flowing. http://docker4.vnet:8086/
If things are working, there will be some measurements that clearly look related to Proxmox resource utilization.
Next Steps
In the next post, we will connect the InfluxDB bucket to a pre-built dashboard using Grafana.
