External Metric Server

In Proxmox VE, you can define external metric servers, which will periodically receive various stats about your hosts, virtual guests and storages.

Currently supported are:

• Graphite (see http://graphiteapp.org )

• InfluxDB (see https://www.influxdata.com/time-series-platform/influxdb/ )

The external metric server definitions are saved in /etc/pve/status.cfg, and can be edited through the web interface.

Graphite server configuration

The default port is set to 2003 and the default graphite path is proxmox.

By default, Proxmox VE sends the data over UDP, so the graphite server has to be configured to accept this. Here the maximum transmission unit (MTU) can be configured for environments not using the standard 1500 MTU.

You can also configure the plugin to use TCP. In order not to block the important pvestatd statistic collection daemon, a timeout is required to cope with network problems.

Influxdb plugin configuration

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
