Question

我正在尝试使用Raspberry Pi轮询TP-LINK路由器的接口MIB（IF：MIB），然后将指标发送到Librato。设置collectd并将其与Librato集成完全没问题 - 我成功地跟踪了其他指标（cpu，内存等）。我遇到的挑战是collectd-snmp插件配置。

我安装了net-snmp，可以＆＃34;看＆＃34;路由器：

pi@raspberrypi ~ $ snmpwalk -v 1 -c public 192.168.0.1 IF-MIB::ifInOctets
IF-MIB::ifInOctets.2 = Counter32: 1206812646
IF-MIB::ifInOctets.3 = Counter32: 1548296842
IF-MIB::ifInOctets.5 = Counter32: 19701783
IF-MIB::ifInOctets.10 = Counter32: 0
IF-MIB::ifInOctets.11 = Counter32: 0
IF-MIB::ifInOctets.15 = Counter32: 0
IF-MIB::ifInOctets.16 = Counter32: 0
IF-MIB::ifInOctets.22 = Counter32: 0
IF-MIB::ifInOctets.23 = Counter32: 0

Pi位于192.168.0.20，路由器位于192.168.0.1。我的collectd.conf如下：

<Plugin snmp>
  <Data "ifmib_if_octets32">
    Type "if_octets"
    Table true
    Instance "IF-MIB::ifDescr"
    Values "IF-MIB::ifInOctets" "IF-MIB::ifOutOctets"
  </Data>
  <Host "localhost">
    Address "192.168.0.1"
    Version 1
    Community "public"
    Collect "ifmib_if_octets32"
    Interval 60
  </Host>
</Plugin>

当我重新开始收集时，我收到以下错误：

pi@raspberrypi ~ $ sudo service collectd restart
[....] Restarting statistics collection and monitoring daemon: collectdNo log handling enabled - turning on stderr logging

. ok

显然无法找到MIB，它似乎甚至看不到路由器的IP。有关如何正确配置的任何建议吗？

我明白了：

<Plugin snmp>
  <Data "if_Octets">
    Type "if_octets"
    Table true
    Values "IF-MIB::ifInOctets" "IF-MIB::ifOutOctets"
  </Data>
  <Host "tp-link">
    Address "192.168.0.1"
    Version 1
    Community "public"
    Collect "if_Octets"
    Interval 60
  </Host>
</Plugin>

如何配置collectd-snmp来轮询路由器？
