+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 server definitions are saved in '/etc/pve/status.cfg'

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