Hi,

be carefull of timeouts, because it could hang pvestatd.
(That's why it was implemented in udp for graphite && influxdb)

Objet: [pve-devel] [PATCH manager] add graphite tcp support

This change allows sending statistics to graphite over TCP. 

So far only UDP is possible, which is not available in some environments, like behind a loadbalancer. 

Configuration example: 
~ $ cat /etc/pve/status.cfg 

graphite: 
server 10.20.30.40 
port 2003 
path proxmox 
proto tcp
