sipp3.6多方案压测脚本
概述
SIP压测工具sipp，免费，开源，功能足够强大，配置灵活，优点多。
有时候我们需要模拟现网的生产环境来压测，就需要同时有多个sipp脚本运行，并且需要不断的调整呼叫并发。
通过python脚本的子进程功能，我们可以很方便的实现sipp的多方案压测功能。
环境
centos7.9
freeswitch1.10.7
sipp v3.6.2_rc1
python 2.7.5
压测方案
Freeswitch部署在137服务器，作为呼叫的信令代理，开放端口5080。
Sipp和python脚本部署在138服务器，sipp的测试方案需要启动4个进程。
Sipp1，uas端，开启5555端口，接收fs137转发的呼叫，并响应接通信令。
Sipp2，uac端，开启6666端口，向fs137发送呼叫，并在接通30秒后挂断电话。
Sipp3，uac端，开启7777端口，向fs137发送呼叫，并接收fs137返回的404信令但不处理。
Sipp4，uac端，开启6668端口，向fs137发送呼叫，并在收到180振铃消息后主动cancel呼叫。
其中，sipp2，sipp3，sipp4三个uac端的进程，每间隔3分钟发起新一轮呼叫，每一轮呼叫运行2分钟。
Sipp1配置脚本
Sipp1，uas端，开启5555端口，接收fs137转发的呼叫，并响应接通信令。
监听10.55.55.138的5555端口，命令和脚本如下。
sudo sipp -i 10.55.55.138 -p 5555 -sf uas-test180cps.xml
uas-test180cps.xml

Python脚本
该Python脚本可以在python2和python3的环境下运行，测试环境只跑了python2。
脚本如下，通过subprocess子进程实现压测方案的自动启停。
sipp-auto.py
# coding=utf-8
# python3 required
import subprocess
import time
import signal
import sys
def signal_handler(sig, frame):
continueflag = 0
for p in processes:
p.terminate()
sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)
commands = [
# "sudo sipp -i 10.55.55.138 -p 5555 -sf uas-test180cps.xml",
"sudo sipp -i 10.55.55.138 -p 6666 -inf call-test.csv -sf uac-test180cps.xml 10.55.55.137:5080 -rp 1000 -r 160 -l 8192 -m 19200 -bg",

]
continueflag = 1
processes = []
commandUas = "sudo sipp -i 10.55.55.138 -p 5555 -sf uas-test180cps.xml"
p = subprocess.Popen(commandUas, shell=True)
processes.append(p)
while 1==continueflag:
for command in commands:
p = subprocess.Popen(command, shell=True)
processes.append(p)
time.sleep(180) # 等待3分钟
for p in processes:
p.wait()
测试
Sipp的配置脚本和python脚本放置到相同目录下。
启动python脚本。
sudo python sipp-auto.py
观察fs资源情况和sipp运行情况。
总结
sipp的github地址：https://github.com/SIPp/sipp
后续会有更多的压测方案和脚本慢慢写。
空空如常
