collectds 网络插件每 100 秒仅发送一次数据

Question

在过去的几个小时里，我一直在用这个头撞墙，所以我在这里问你们。

我有一个 collectd 实例，它被设置为获取 statsd 指标并使用network插件将它们路由到主 collectd 实例，然后通过write_graphite插件将它们发送到 influxdb 。

向statsd插件发送指标有效（我已经检查tcpdump并使用csv插件作为调试工具）。

当network插件将收集到的指标发送到“主要”collectd 实例时，这成为一个问题。该network插件似乎每 100 秒或重新启动时只发送一次数据（我猜它在停止时刷新缓冲区）。

以下是客户端机器的配置：

/etc/collectd/collectd.conf

Hostname "collectd.client"
FQDNLookup false
BaseDir "/var/lib/collectd"
PluginDir "/usr/lib/collectd"
TypesDB "/usr/share/collectd/types.db"
AutoLoadPlugin false
Interval 10

LoadPlugin logfile

<Plugin logfile>
   LogLevel "info"
   File "/var/log/collectd.log"
   Timestamp true
   PrintSeverity true
</Plugin>

<Include "/etc/collectd/conf.d">
    Filter "*.conf"
</Include>

/etc/collectd/conf.d/network.conf

LoadPlugin network

<Plugin "network">
        <Server "main-instance-ip" "25826">
            SecurityLevel "Encrypt"
            Username "collectd"
            Password "xxxxxxxx"
    </Server>
</Plugin>

/etc/collectd/conf.d/collectd.statsd.conf

LoadPlugin statsd

<Plugin statsd>
    Host "0.0.0.0"
    Port "8125"
</Plugin>

这是tcpdump运行一段时间的输出：

从输出看来，它现在决定每~2 分钟运行一次。

您收集了多少值？

据我所知，network插件在缓冲区已满时发送数据。尝试使用MaxPacketSize 1024指令，或收集更多数据。
