Linux command – Stressful Application Test (Network)

前面有使用過 Stressful Application Test (Stressapptest) https://benjr.tw/96740 這邊針對他的網路測試來做說明.

測試環境為 Ubuntu16.04 64bits

Net Copy

Stressapptest 也可以透過網路來進行測試,需要使用兩台機器,並使用下面兩個參數.

• -n ipaddr : add a network thread connecting to system at ‘ipaddr’.
• –listen : run a thread to listen for and respond to network threads.

-n 為待測端要指定 listen 的 IP.另外一台使用 –list 等待資料傳輸.

root@ubuntu:~# stressapptest -s 100 -M 500 --listen

IP – 172.16.15.135

可以觀察到 Memory 與 Net 皆有傳輸量.

我們也可以在單一台系統指定 loopback 127.0.0.1 + listen 為測試網路介面,這樣就不需要額外一台機器做網路測試,但只有傳輸沒有接收的封包,stressapptest 會有 Log: Net thread did not receive any data, exiting 的訊息.
