我目前遇到了让 collectd 5.4.0 与 graphite/carbon 一起工作的问题。
我目前正在使用带有 collectd 的 write_graphite 插件，其配置如下：
<Plugin write_graphite>
<Carbon>
Host "127.0.0.1"
Port "2003"
#Prefix "collectd."
Protocol "udp"
EscapeCharacter "_"
#StoreRates true
#AlwaysAppendDS false
SeparateInstances true
</Carbon>
</Plugin>
然而，graphite 表示我的数据无效
13/07/2014 23:32:52 :: invalid line received from client 127.0.0.1:43335, ignoring
我对发送到 graphite 的数据做了一些 ngrep：
