zabbix监控mysql多实例自发现监控
系统运维工程师 李超1、定义每个实例的端口
cat mysql_port
33063307330833093310
331133123313 2、给所有实例创建一个zabbix用户只允许本地访问，生产环境具体权限各位看官自己看着给吧O(∩_∩)O
GRANT ALL PRIVILEGES ON *.* TO zabbix@'127.0.0.1' IDENTIFIED BY 'zabbix'; 3、创建自动发现MySQL端口脚本
cat /data/PRG/zabbix/scripts/discovery_mysql.sh
#!/bin/bash
# -------------------------------------------------------------------------------# Script_name: discovery_mysql.sh # Revision: 1.0# Date: 2017/03/09# Author: kbsonlong
# Email: kbsonlong@gamil.com
# Website: www.along.party
# -------------------------------------------------------------------------------res=`cat /data/PRG/zabbix/scripts/mysql_port|grep -v "^#"`
port=($res)
printf '{\n' printf '\t"data":[\n' for key in ${!port[@]}
do
if [[ "${#port[@]}" -gt 1 && "${key}" -ne "$((${#port[@]}-1))" ]];then
printf '\t {\n'
printf "\t\t\t\"{#MYSQLPORT}\":\"${port[${key}]}\"},\n"
else [[ "${key}" -eq "((${#port[@]}-1))" ]]
printf '\t {\n'
printf "\t\t\t\"{#MYSQLPORT}\":\"${port[${key}]}\"}\n"
fi doneprintf '\t ]\n' printf '}\n' 4、创建MySQL检测脚本
# cat /data/PRG/zabbix/scripts/check_Multimysql.sh #!/bin/bash
# -------------------------------------------------------------------------------# FileName: check_Multimysql.sh# Revision: 1.0# Date: 2017/03/09# Author: kbsonlong

# -------------------------------------------------------------------------------
# 用户名
MYSQL_USER='zabbix'
# 密码
MYSQL_PWD='zabbix'
# 主机地址/IP
MYSQL_HOST='127.0.0.1'
# 端口
MYSQL_PORT=$2
# 数据连接
MYSQL_CONN="/usr/bin/mysqladmin -u${MYSQL_USER} -p${MYSQL_PWD} -h${MYSQL_HOST} -P${MYSQL_PORT}"##help函数
help() { echo "Usage:$0port"}
# 参数是否正确if [ $# -lt "2" ];then
echo "参数缺失!"
help
exit 2fi
# 获取数据case $1 in
ping)
result=`${MYSQL_CONN} ping | grep -c alive`
echo $result
;;
Uptime)
result=`${MYSQL_CONN} status|cut -f2 -d":"|cut -f1 -d"T"`
echo $result
;;

result=`${MYSQL_CONN} extended-status |grep -w "Com_update"|cut -d"|" -f3`
echo $result
;;

echo $result

echo $result
;;

echo $result
;;
Questions)

echo $result
;;
Com_insert)
result=`${MYSQL_CONN} extended-status |grep -w "Com_insert"|cut -d"|" -f3`
echo $result

*)
help

esac 5、测试脚本是否正常
# bash discovery_mysql.sh { "data":[
{ "{#MYSQLPORT}":"3306"},
{ "{#MYSQLPORT}":"3307"},
{ "{#MYSQLPORT}":"3308"},
{ "{#MYSQLPORT}":"3309"},
{ "{#MYSQLPORT}":"3310"},
{ "{#MYSQLPORT}":"3311"},
{ "{#MYSQLPORT}":"3312"},
{ "{#MYSQLPORT}":"3313"}
]
}
# bash check_Multimysql.sh 参数缺失!Usage:check_Multimysql.shport
# bash check_Multimysql.sh ping 33061# bash check_Multimysql.sh Uptime 330618180446 6、zabbix agent配置文件添加自定义脚本，并重启zabbix agent
vim /data/PRG/zabbix/etc/zabbix_agentd.conf
UserParameter=mysql_discovery
[*],/bin/bash /data/PRG/zabbix/scripts/discovery_mysql.sh#####$1==command $2===port
UserParameter=mysql.status
[*],/data/PRG/zabbix/scripts/check_mysql.sh $1 $2 UserParameter=mysql.ping
[*],/data/PRG/zabbix/scripts/check_mysql.sh ping $1 /etc/init.d/zabbix_agentd restart
7、使用zabbix_get检查定义的key是否生效
# /usr/local/zabbix/bin/zabbix_get -s 192.168.62.200 -k mysql.ping
1# /usr/local/zabbix/bin/zabbix_get -s 192.168.62.200 -k mysql.status18180813# /usr/local/zabbix/bin/zabbix_get -s 192.168.62.200 -k mysql.status18180842# /usr/local/zabbix/bin/zabbix_get -s 192.168.62.200 -k mysql.status18180847# /usr/local/zabbix/bin/zabbix_get -s 192.168.62.200 -k mysql.status58803854473 8、导入模板Template Multi Mysql.xml
9、被监控主机关联模板
