ActiveMQ消息傳輸時間

Question

在ActiveMQ中，我能否檢測消息從發佈者傳遞給訂閱者需要多少時間？ 或者我可以看到消息從發佈服務器到主題（JMS服務）並從（JMS服務）主題到Subsriber的單獨計時？

Answer 1

有一個Maven plugin for AMQ performance testing，它可能是你正在尋找。

否則，您可以通過使用一些負載測試工具（如Apache jMeter）進行一些測量，然後看看您可以讀/寫多少條消息/秒。

請注意，如果您堅持不懈和/或事務處理，您將會有相當大的差異。

更新：

你可以通過配置的conf/log4j.properties和設置可能做日誌的內容：數據

log4j.rootLogger=TRACE, logfile, console 

然後/ activemq.log你可以得到一些信息，認沽信息。數字代表的並不是很明顯，所以你應該確保定義一個測試場景。下面的時間戳是從提出到通過HermesJMS隊列（myQueue中）到ActiveMQ的消息：

當JMS消息在消費者到達時，你可以看看到JMSTimestamp頭屬性。根據Javadoc：

JMSTimestamp標題字段包含消息被傳遞的時間 off要發送。

然後，你可以簡單地從當前系統時間減去JMSTimestamp和飛行計算time taken通過JMS消息。
