请参考：

新版的zabbix 有监控mysql的key, 只需要在server 的item 中添加item.

1    /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf  ###agent 端无需要脚本，就能监控mysql status,  需要监控mysql的状态，请在mysql 中 输入 show status

# For all the following commands HOME should be set to the directory that has .my.cnf file with password information.# Flexible parameter to grab global variables. On the frontend side, use keys like mysql.status[Com_insert].# Key syntax is mysql.status[variable].UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/var/lib/zabbix mysql -N | awk '{print $$2}'# Flexible parameter to determine database or table size. On the frontend side, use keys like mysql.size[zabbix,history,data].# Key syntax is mysql.size[<database>,<table>,<type>].# Database may be a database name or "all". Default is "all".# Table may be a table name or "all". Default is "all".# Type may be "data", "index", "free" or "both". Both is a sum of data and index. Default is "both".# Database is mandatory if a table is specified. Type may be specified always.# Returns value in bytes.# 'sum' on data_length or index_length alone needed when we are getting this information for whole database instead of a single tableUserParameter=mysql.size[*],echo "select sum($(case "$3" in both|"") echo "data_length+index_length";; data|index) echo "$3_length";; free) echo "data_free";; esac)) from information_schema.tables$([[ "$1" = "all" || !
