ubuntu環境mosquitto安裝及測試最大連線數

#!/bin/bash
c=1 -d
while [ $c -le 5000 ]
do
mosquitto_sub -d -t hexiang -k 900 &
 (( c++ ))
done

檢視連線數

netstat -na | awk '/^tcp/ {++S[$NF]} END {for(a in S) print a, S[a]}'

 netstat -na|grep ESTAB|grep 1883|wc -l

檢視cpu 佔用高的執行緒

ps H -eo user,pid,ppid,tid,time,%cpu,cmd --sort=%cpu
 

結束程序及所有連線

kill -9 `ps -ef|grep mosquitto|awk '{print $2}'`

#(max processes)
ulimit -u 12000
#(max files)
ulimit -n 12000

windows dos 命令檢視 連線數

netstat -an|find ":1883" |find  "ESTABLISHED" /c

#####訂閱遠端主機
mosquitto_sub -h 192.168.11.16 -t hexiang
