我在我的服务器上有3个默认configuration的munin-node，我想创build一个显示总输出带宽的摘要图表。
这是我做minin.conf：
[example.com;aggregation] update no total_bandwidth.graph_title Aggregated bandwidth total_bandwidth.upload.label upload total_bandwidth.upload.sum \ serv1.example.com:if_eth0:up \ serv2.example.com:if_eth0:up \ serv3.example.com:if_eth0:up 但它不工作，我只能得到破碎的图像，而不是graphics。 在munin-graph.log中：
[RRD ERROR] Unable to graph /var/www/munin/example.com/aggregation/total_bandwidth-month.png : opening '': No such file or directory
编辑：
遵循http://waste.mandragor.org/munin_tutorial/munin.html ，我已经尝试过，这不起作用更好：
[example.com;aggregation] update no total_bandwidth.graph_title Our total bandwidth total_bandwidth.out.sum example.com;serv1.example.com:if_eth0:up example.com;serv2.example.com:if_eth0:up total_bandwidth.out.draw STACK total_bandwidth.out.label Out bandwidth total_bandwidth.in.sum example.com;serv1.example.com:if_eth0:down example.com;serv2.example.com:if_eth0:down total_bandwidth.in.draw STACK total_bandwidth.in.label In bandwidth
只要用if_eth0:downreplaceif_eth0:down 。
