Producer Completed
Consumer Completed

我猜是NP是公布的数字,NC是每个窗口消耗的数字。第一个数字是发送/接收的消息的数量。第二个和第三个数字是什么意思?

以下是QpidBench.java的来源:https://svn.apache.org/repos/asf/qpid/trunk/qpid/java/tools/src/main/java/org/apache/qpid/tools/QpidBench.java

以下是qpid-bench命令的选项:

$ qpid-bench --help
   qpid-bench <options>
  -b, --broker    (localhost)   the broker hostname
  -p, --port      (5672)        the broker port
  -c, --count     (1000000)     the number of messages to send/receive, 0 means no limit
  -w, --window    (100000)      the number of messages to send before blocking, 0 disables
  --sample        (100000)      print stats after this many messages, 0 disables
  -i, --interval  (100000)      sets both --window and --sample
  -s, --size      (1024)        the message size
  -m, --mode      (BOTH)        one of publish, consume, or both
  --timestamp     (false)       set timestamps on each message if true
  --mesage-id     (false)       set the message-id on each message if true
  --message-cache (false)       reuse the same message for each send if true
  --persistent    (false)       set the delivery-mode to persistent if true
  --jms-publish   (false)       use the jms client for publish
  --jms-consume   (false)       use the jms client for consume
  --jms           (false)       sets both --jms-publish and --jms-consume
  -h, --help                    prints this message

由“double cumulative = 1000 *(double)count /(double)(time-start)”定义的第一个累积数字;“在QPidBench.java中。即每个样本期间公布或消费的总数。

第二个数字间隔由“double interval = 1000 *((double)opts.sample /(double)(time-lastTime))”定义;“在QpidBench.java中。即每个样本期间公布或消费的数字。

count是发布/消耗的消息数,opts.sample是qpid-bench运行时选项中定义的样本大小。
