Use InfluxDB 2 as a Metric Server for Proxmox

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.

Hi Vince!

Very nice article. I just build the connection to InfluxDB 2 as well and I am exploring the data in the InfluxDB Data Explorer. Unfortunately I cannot find the Proxmox Datacenter object. I do see every host in the Datacenter but not the item itself. Were you able to find it?

Hi Jeroen,

Glad you found it helpful! No, I wasn’t able to find a “datacenter” object either.
