我的所有服务器上的 munin-node 都具有基本的默认配置，我想创建一个显示 http 输入/输出总带宽的摘要图表，以及另一个显示所有接口输入/输出总带宽的图表。
[编辑] 按照第一个发帖人的建议后，我目前到这里；
我正在尝试实现 if_eth0 服务的正常运行/宕机的汇总 SUM 图
根据常见问题解答中的详细信息； http://munin-monitoring.org/wiki/faq#Q:HowdoIusefieldname.sum
以及详细的例子； http://munin-monitoring.org/wiki/aggregate_examples
以及这篇关于聚合物的有趣文章； http://blog.loftninjas.org/2010/04/08/an-evening-with-munin-graph-aggregation/
我在 /etc/munin/munin.conf 中定义以下内容我的主机；
[cirrusj1605.hpl.com]
address 19x.xx.xx.205
use_node_name yes
[cirrusj1606.hpl.com]
address 19x.xx.xx.206
use_node_name yes
...
以及像这样的聚合虚拟主机；
[hpl.com;aggregates] 更新 无联系人 无
total_bandwidth.graph_title Aggregated bandwidth
total_bandwidth.upload.label upload
total_bandwidth.upload.sum \
cirrusj1605.hpl.com:if_eth0:up \
cirrusj1606.hpl.com:if_eth0:up
如果我尝试手动运行 munin-graph，则在生成每个图表时会出现以下错误；
2011/02/24 20:04:39 [RRD 错误] 无法绘制图表 /var/www/html/munin/hpl.com/aggregates/total_bandwidth-month.png : az1_0、UN、0、az1_0、IF、、+ 中的 rpn 表达式无效
完整的跟踪如下，对于问题可能是什么，有什么建议吗？
谢谢，T

答案1
是的，它是在服务器端通过创建组合图来完成的。
基本上，它是通过在 munin 服务器配置 ( munin.conf) 中描述一个新图表来完成的，其中绘制的数据是两个数据源的总和：
[some.machine.boo]
total_http_bw.graph_order total_received
total_http_bw.graph_title HTTP traffic recived by machine1 and machine2
total_http_bw.graph_vlabel Kb/s
total_http_bw.total_received.label HTTP received traffic
total_http_bw.total_received.sum \
machine1.machine.boo:http_bw:received \
machine2.machine.boo:http_bw:received
您可以找到一个例子堆叠（将两个数据源绘制成一个在另一个之上的图形）在 munin 网站上。如果您想要绘制两个数据源的总和，则可以使用函数total_received.sum代替total_received.stack。
[编辑] 我在这个答案中添加了需要网络接口带宽的部分，因为它可以更完整地回答原始问题（我无法选择 2 个正确的答案等）
我曾有一个很多让网络接口放弃它们的值作为 SUM 的麻烦，因此这里是大量随机试验和错误更改的最终结果，以获得多个 munin 节点的 SUM 折线图
[mydomain.com;aggregates]
total_bandwidth.graph_args --base 1000 -l 0
total_bandwidth.cdef 0
total_bandwidth.graph_category Network
total_bandwidth.graph_title Aggregated bandwidth
total_bandwidth.graph_vlabel Bits/sec
total_bandwidth.upload.label upload
total_bandwidth.total.graph yes
total_bandwidth.upload.sum \
mybox1.mydomain.com:if_eth0.up \
mybox2.mydomain.com:if_eth0.up
total_bandwidth.upload.type COUNTER
total_bandwidth.download.type COUNTER
total_bandwidth.download.label download
total_bandwidth.graph_order upload download
total_bandwidth.total.graph no
total_bandwidth.download.sum \
mybox1.mydomain.com:if_eth0.down \
mybox2.mydomain.com:if_eth0.down
我怀疑其中一些指令要么是不必要的，要么是完全错误的，但我希望它能成为任何试图实现相同目标的人的一个工作起点。
我还怀疑，如果您明确确保所有主机都在聚合组中，例如 mydomain.com，即使您的主机在本地命名不正确，例如hostname -f错误，它也会更好地工作
