如何在munin中獲得總頻寬圖
我在所有伺服器上的基本預設配置中都有 munin-node，我想創建一個摘要圖表，顯示輸入/輸出 http 的總頻寬和另一個顯示所有介面的總頻寬輸入/輸出的圖表。
$$ Edit $$在遵循第一個海報建議之後，我目前到這裡； 我正在嘗試為 if_eth0 服務實現向上/向下的聚合 SUM 圖
根據常見問題解答中的詳細資訊； http://munin-monitoring.org/wiki/faq#Q:HowdoIusefieldname.sum
和詳細的例子； http://munin-monitoring.org/wiki/aggregate_examples
還有這篇關於聚合的有趣文章； http://blog.loftninjas.org/2010/04/08/an-evening-with-munin-graph-aggregation/
我在 /etc/munin/munin.conf 中有以下內容來定義我的主機；
[cirrusj1605.hpl.com] address 19x.xx.xx.205 use_node_name yes [cirrusj1606.hpl.com] address 19x.xx.xx.206 use_node_name yes…
和一個像這樣的聚合虛擬主機；
$$ hpl.com;aggregates $$ 更新沒有聯繫人沒有
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如果我嘗試手動執行 munin-graph，則在生成每個圖表時都會出現以下錯誤；
2011/02/24 20:04:39
$$ RRD ERROR $$無法繪製 /var/www/html/munin/hpl.com/aggregates/total_bandwidth-month.png ：無效的 rpn 表達式：az1_0,UN,0,az1_0,IF,,+ 完整的跟踪如下，關於問題可能是什麼的任何建議？
謝謝，

是的，它是通過創建組合圖在伺服器端完成的。
基本上它是通過在 munin 伺服器配置 (
munin.conf) 中描述一個新圖表來完成的，其中繪製的數據是兩個數據源的總和：[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您可以在 munin 網站上找到一個堆疊範例（將兩個數據源一個在另一個之上）。如果要繪製兩個數據源的總和，可以使用
total_received.sum函式而不是total_received.stack.$$ edit $$我在此答案中添加了具有網路介面頻寬所需的節，因為它為原始問題提供了更完整的答案（我無法選擇 2 個正確答案等） 我在讓網路介面放棄它們作為 SUM 的值時遇到了很多麻煩，所以這裡是大量隨機試驗和錯誤更改以獲得多個 munin 節點的 SUM 折線圖的最終結果
[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我懷疑其中一些指令要麼是不必要的，要麼是完全錯誤的，但我希望它是任何試圖實現相同目標的人的工作起點。
我還懷疑，如果您明確確保所有主機都在聚合組中，例如 mydomain.com，即使您的主機在本地
hostname -f被錯誤地命名（例如錯誤） ，它也會更好地工作
