1.memcached

apt-get  install memcached 
systemctl start memcached   #端口11211 

apt-get install nmap
#命令测试获取监控值
echo -e "stats\nquit" | nc 127.0.0.1 11211
root@ubuntu:~# echo -e "stats\nquit" | nc 127.0.0.1 11211 | grep "total_connections" | awk '{print $3}'

1.1.配置文件修改

root@ubuntu:/etc/zabbix/zabbix_agentd.d# ls
memcached.conf  memcached.sh  

#在主配置文件打开，默认是打开的
vim /etc/zabbix/zabbix_agentd.conf 
------------------------------------------------------
Include=/etc/zabbix/zabbix_agentd.d/*.conf
------------------------------------------------------

vim  /etc/zabbix/zabbix_agentd.d/memcached.conf
-------------------------------------------------------------------------------------
UserParameter=memcached_status[*],/bin/bash /etc/zabbix/zabbix_agentd.d/memcached.sh $1 $2 $3
-------------------------------------------------------------------------------------
memcached.sh 这个脚本是加了执行权限的,但是为啥前面要加上/bin/bash,zabbix_get才能获取到值？？

1.2.监控脚本

#!/bin/bash
memcached_status(){
M_PORT=$1
M_COMMAND=$2
echo -e "stats\nquit" | nc 127.0.0.1 "$M_PORT" | grep "STAT $M_COMMAND " | awk '{print $3}'
}
main(){
case $1 in
memcached_status)
memcached_status $2 $3
;;
esac
}
main $1 $2 $3

chmod a+x memcached.sh
#测试脚本
root@ubuntu:/etc/zabbix/zabbix_agentd.d# bash memcached.sh memcached_status 11211 total_connections

#在[192.168.47.104测试]
/apps/zabbix_agent/bin/zabbix_get -s 192.168.47.105 -p 10050 -k "memcached_status[memcached_status,11211,total_connections]"

1.4.把模板导入及查看

zabbix-redis/memcache监控_zabbix-redis/memcach_02

2.redis

2.1.安装

apt-get install redis
systemctl start redis
systemctl enable redis

#获取监控值脚本
root@ubuntu:/etc/zabbix/zabbix_agentd.d# pwd
/etc/zabbix/zabbix_agentd.d

#获取监控值
root@ubuntu:/etc/zabbix/zabbix_agentd.d# echo -e "INFO\n quit" | nc 127.0.0.1 "6379" |grep -w used_cpu_sys |awk -F":" '{print $2}'
0.27

脚本里面用nc命令就一直卡住，换成ncat命令后可以了，后面需要了解下这是为啥

2.2.获取监控值脚本

redis.sh

#!/bin/bash
redis_status(){
R_PORT=$1
R_COMMAND=$2
(echo -en "INFO \r\n";sleep 1;) | ncat 127.0.0.1 "$R_PORT" > /etc/zabbix/zabbix_agentd.d/redis_"$R_PORT".tmp
REDIS_STAT_VALUE=$(grep ""$R_COMMAND":" /etc/zabbix/zabbix_agentd.d/redis_"$R_PORT".tmp| cut -d ':' -f2)
echo $REDIS_STAT_VALUE
}
help(){
echo "${0} + redis_status+ PORT + COMMAND"
}
main(){
case $1 in
redis_status)
redis_status $2 $3
;;
*)
help
;;
esac
}
main $1 $2 $3

chmod +x redis.sh
#测试
bash redis.sh redis_status 6379 used_cpu_sys

zabbix-redis/memcache监控_zabbix-redis/memcach_06

2.3.测试

在[192.168.47.104测试]

在[192.168.47.102测试]
