如何配置Munin来监控ppp0

我在我的Ubuntu Jaunty笔记本电脑上使用Munin。它显示了除ppp0之外的所有内容的强大图表，我用它来连接到互联网。所以我需要配置munin来显示ppp0使用图。

我尝试浏览文档和一些教程，并在munin-node插件目录中添加了if_ppp0和if_error_ppp0。创建了两个符号链接，正如我所说，它指向正确的插件，if_和if_error（只跟踪if_eth0和if_error_eth0的操作，并为ppp0完成相同操作）。但这还不够。ppp0不在图表中。

我找不到任何建议在监视池中包含ppp0的配置行。有点令人惊讶的是，考虑到popin的流行程度，没有任何关于ppp的文章。

我很擅长Perl和bash，之前也编程过rrd。所以我编辑了if_和if_error perl文件的插件，并将看起来像“eth | wlan | ....”的正则表达式改为“eth | ppp | wlan | ....”。什么都没有被打破，也没有任何东西得到解决。我似乎必须在其他地方做别的事情，但不知道它是什么。请帮忙。

默认的eth脚本使用ethtool，它不适用于ppp链接。

eth脚本也使用COUNTER而不是DERIVE，每次重新连接ppp链接时都会出现错误峰值。

这是我的脚本（更改up.max，down.max到你的ppp链接带宽）...
