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

Martin Verges martin.verges at croit.io
Mon Nov 4 16:48:04 CET 2019


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
