External Metric Server – Proxmox VE

Proxmox VE sends the data over UDP, so the influxdb server has to be configured for
this. The MTU can also be configured here, if necessary.

Here is an example configuration for influxdb (on your influxdb server):

[[udp]]
   enabled = true
   bind-address = "0.0.0.0:8089"
   database = "proxmox"
   batch-size = 1000
   batch-timeout = "1s"

With this configuration, your server listens on all IP addresses on port 8089,
and writes the data in the proxmox database

Alternatively, the plugin can be configured to use the http(s) API of InfluxDB 2.x.
InfluxDB 1.8.x does contain a forwards-compatible API endpoint for this v2 API.

To use it, set influxdbproto to http or https (depending on your configuration).
By default, Proxmox VE uses the organization proxmox and the bucket/db proxmox
(They can be set with the configuration organization and bucket, respectively).

Since InfluxDB’s v2 API is only available with authentication, you have
to generate a token that can write into the correct bucket and set it.

In the v2 compatible API of 1.8.x, you can use user: password as token
(if required), and can omit the organization since that has no meaning in InfluxDB 1.x.

You can also set the HTTP Timeout (default is 1s) with the timeout setting,
as well as the maximum batch size (default 25000000 bytes) with the
max-body-size setting (this corresponds to the InfluxDB setting with the
same name).
