 Currently supported are:
 
- * Graphite (see http://graphiteapp.org )

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

+configured for environments not using the standard *1500* MTU.

-Multiple Definitions and Example
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+With this configuration, your server listens on all IP addresses on port 8089,
+and writes the data in the *proxmox* database
 
-The *id* is optional, but if you want to have multiple definitions of a single
-type, then the ids must be defined and different from each other.
+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.
 
-Here is an example of a finished status.cfg
+To use it, set 'influxdbproto' to 'http' or 'https' (depending on your configuration).
+By default, {pve} uses the organization 'proxmox' and the bucket/db 'proxmox'
+(They can be set with the configuration 'organization' and 'bucket' respectively).
 
-----
-graphite:
-    server 10.0.0.5
+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.
 
-influxdb: influx1
-    server 10.0.0.6
-    port 8089
+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.
 
-influxdb: influx2
-    server 10.0.0.7
-    port 8090
-----
+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).
