zabbix监控mysql

zabbix从3.0开始就自带mysql的监控模板。

[root@mysql zabbix_agent]# cat zabbix_agentd.conf| grep Include
### Option: Include
# Include=
# Include=/usr/local/etc/zabbix_agentd.userparams.conf
Include=/app/zabbix_agent/zabbix_agentd.conf.d/*.conf
# Include=/usr/local/etc/zabbix_agentd.conf.d/*.conf
#我要把userparameter放在zabbix_agentd.conf.d目录下，首先要改agent的配置文件

　　

[root@mysql zabbix_agentd.conf.d]# cat /app/zabbix_agent/zabbix_agentd
zabbix_agentd         zabbix_agentd.conf    zabbix_agentd.conf.d/ 
[root@mysql zabbix_agentd.conf.d]# cat /app/zabbix_agent/zabbix_agentd.conf.d/mysql.conf 
UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/app/zabbix_agent/zabbix_agentd.conf.d mysql -N | awk '{print $$2}'
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=/app/zabbix_agent/zabbix_agentd.conf.d mysql -N'

UserParameter=mysql.ping,HOME=/app/zabbix_agent/zabbix_agentd.conf.d mysqladmin ping | grep -c alive
UserParameter=mysql.version,mysql -V
#创建一个自定义监控项文件

　　

[root@mysql zabbix_agentd.conf.d]# cat /app/zabbix_agent/zabbix_agentd.conf.d/.my.cnf 
[client]
user=zabbix
password=zabbix
#创建一个zabbix访问本机mysql的账户

　　

mysql>  grant usage on *.* to zabbix@'localhost' identified by 'zabbix';   
#创建一个账户

　　

[root@mysql ~]# cd /app/zabbix_agent/
[root@mysql zabbix_agent]# ls
