In {pve}, 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
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
[thumbnail="screenshot/gui-datacenter-metric-server-graphite.png"]
|
|
|
|
The default port is set to *2003* and the default graphite path is *proxmox*.
|
|
|
|
By default, {pve} 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
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
[thumbnail="screenshot/gui-datacenter-metric-server-influxdb.png"]
|
|
|
|
{pve} 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
|
