JMeter中的TCP采樣器請求

Question

我有一個充當TCP服務器的Java程序，我需要測試其性能。 編寫了一個tcp sampler jmeter請求，我能夠正確獲取響應數據，但是響應代碼為500，並且日志中拋出錯誤

TCPClientClassName : TCPClientImpl
Response : 500
Checked "Reuse Connection", "Set No Delay" options

Thread Name: Thread Group 1-1
Sample Start: 2014-10-15 17:33:51 IST

首先，要檢查您的TCP服務器是否確實在運行，請運行：

telnet主機：端口

如果仍然失敗，則可能是因為JMeter與托管TCP服務器的目標服務器之間沒有打開防火牆
