## 查看自定义脚本 ##

# 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 table
    UserParameter=mysql.size[*],bash -c '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" || ! "$1" ]] || echo " where table_schema=\"$1\"")$([[ "$2" = "all" || ! "$2" ]] || echo "and table_name=\"$2\"");" | HOME=/var/lib/zabbix mysql -N'
    
    UserParameter=mysql.ping,mysqladmin -uroot -p'123123' -P33061 -hlocalhost ping | grep -c alive
    UserParameter=mysql.version,mysql -V

执行命令发现相同报错：mysqladmin -uroot -p’123123’ -P33061 -hlocalhost ping | grep -c alive

## 解决 ##

修改mysqladmin命令

mysqladmin -uroot -p'123123' -P33061 -hlocalhost ping 2>/dev/null | grep -c alive

效果
