ubuntu环境mosquitto安装及测试最大连接数
#!/bin/bash
c=1 -d
while [ $c -le 5000 ]
do
mosquitto_sub -d -t hexiang -k 900 &
(( c++ ))
done
查看连接数
netstat -na | awk '/^tcp/ {++S[$NF]} END {for(a in S) print a, S[a]}'
netstat -na|grep ESTAB|grep 1883|wc -l
查看cpu 占用高的线程
ps H -eo user,pid,ppid,tid,time,%cpu,cmd --sort=%cpu
结束进程及所有连接
kill -9 `ps -ef|grep mosquitto|awk '{print $2}'`
#(max processes)
ulimit -u 12000
#(max files)
ulimit -n 12000
windows dos 命令查看 连接数
netstat -an|find ":1883" |find "ESTABLISHED" /c
#####订阅远程主机
