一、linux环境下监控MySQL
Zabbix Server自带了MySQL插件来监控mysql数据库的模板,只需要配置好agent客户端,然后在web端给主机增加模板就行了
监控项目:
Com_update: mysql执行的更新个数
Com_select: mysql执行的查询个数
Com_insert: mysql执行插入的个数
Com_delete: 执行删除的个数
Com_rollback: 执行回滚的操作个数
Bytes_received: 接受的字节数
Bytes_sent: 发送的字节数
Slow_queries: 慢查询语句的个数
Com_commit: 确认的事物个数
Com_begin: 开始的事物个数
Uptime: 服务器已启动的秒数
Questions: 客户端发送到服务器的语句个数
1)创建zabbix链接MySQL的用户名,密码并授予权限。
mysql> grant all on *.* to zabbix@‘localhost‘ identified by "123456”; mysql> flush privileges;
2)在zabbix_agent服务目录下创建 .my.cnf 连接文件
cd /usr/local/zabbix/etc/ vim .my.cnf [client] user=zabbix password=123456
注意:
如果在数据库grant授权时,针对的是localhost,这个.my.cnf里面就不用加host参数了【如上配置】
但如果grant授权时针对的是本机的ip(如192.168.1.25),那么在.my.cnf文件里就要加上host参数进行指定:host=192.168.1.25
3)配置MySQL的key文件
这个可以从zabbix安装时的解压包里拷贝过来:
cp /usr/local/src/zabbix3.0.3/conf/ zabbix_agentd/userparameter_mysql.conf /usr/local/zabbix/etc/zabbix_agentd.conf.d/
4)替换zabbix安装路径,注意如果MySQL没配置好环境变量可能找不到MySQL命令,可以用MySQL全路径
看到类似 HOME=/var/lib/zabbix 的路径设置,把路径全都替换为 /usr/local/zabbix/etc/,也就是上面的.my.cnf文件所在的目录路径。
cd /usr/local/zabbix/etc/zabbix_agentd.conf.d/
vim userparameter_mysql.conf
# 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=/usr/local/zabbix/etc/ mysql -N | awk ‘{print $$2}‘
# Flexible parameter to determine database or table size. On the frontend side, use keys like mysql.size[zabbix,history,data].
# Key syntax is mysql.size[<database>,<table>,<type>].
# Database may be a database name or "all". Default is "all".
# Table may be a table name or "all". Default is "all".
# Type may be "data", "index", "free" or "both". Both is a sum of data and index. Default is "both".
# Database is mandatory if a table is specified. Type may be specified always.
# Returns value in bytes.
# ‘sum‘ on data_length or index_length alone needed when we are getting this information for whole database instead of a single table
UserParameter=mysql.size[*],bash -c ‘echo "select sum($(case "$3" in both|"") echo "data_length+index_length";; data|index) echo "$3_length";; free) echo "data_free";; esac)) from information_schema.tables$([[ "$1" = "all" || ! "$1" ]] || echo " where table_schema=\"$1\"")$([[ "$2" = "all" || ! "$2" ]] || echo "and table_name=\"$2\"");" | HOME=/usr/local/zabbix/etc/ mysql -N‘
UserParameter=mysql.ping,HOME=/usr/local/zabbix/etc/ mysqladmin ping | grep -c alive
UserParameter=mysql.version,mysql -V
%s#/var/lib/zabbix#/usr/local/zabbix/etc/# #用命令替换也可以用这个shell脚本监控,包括主从监控:
### MySQL DB Infomation
UserParameter=mysql.status[*],echo"show global status where Variable_name=‘$1‘;"|mysql--defaults-file=/usr/local/zabbix/etc/.my.cnf -N|awk ‘{print $$2}‘
UserParameter=mysql.variables[*],echo"show global variables where Variable_name=‘$1‘;"|mysql--defaults-file=/usr/local/zabbix/etc/.my.cnf -N|awk ‘{print $$2}‘
UserParameter=mysql.ping,mysqladmin--defaults-file=/usr/local/zabbix/etc/.my.cnf ping|grep -c alive
UserParameter=mysql.version,echo"select version();"|mysql--defaults-file=/usr/local/zabbix/etc/.my.cnf -N
#### MySQL Master Information
UserParameter=mysql.master.Slave_count,echo"show slave hosts;"|mysql--defaults-file=/usr/local/zabbix/etc/.my.cnf -N|wc -l
UserParameter=mysql.master.Binlog_file,echo"show master status;"|mysql--defaults-file=/usr/local/zabbix/etc/.my.cnf -N|awk ‘{print $1}‘|awk -F.‘{print $1}‘

UserParameter=mysql.slave.Read_Master_Log_Pos,echo"show slave status\G"|mysql--defaults-file=/usr/local/zabbix/etc/.my.cnf|grep"Read_Master_Log_Pos"|awk ‘{print $2}‘5)修改zabbix_agentd.conf配置文件,开启额外加载,就是去掉前面的#号
vim zabbix_agentd.conf Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/
6)重启zabbix_agentd服务
/etc/init.d/zabbix_agentd restart
7)测试看能否获取到数据
# zabbix_get -s 127.0.0.1 -p 10050 -k mysql.status[Com_select] 200661
8)登陆zabbix监控界面,在“配置”里为主机添加模板,完成监控。
二、windows下的MySQL监控
要想在Windows上取得MySQL的状态数据,可以用vbs脚本运行mysql命令
1)在d:\Zabbix\Scripts\目录下新建两个脚本文件内容如下:
mysql_ping.vbs
Set objFS =CreateObject("Scripting.FileSystemObject")
Set objArgs = WScript.Arguments
str1 = getCommandOutput("D:\SOFT_PHP_PACKAGE\mysql\bin\mysqladmin-ucactiuser -pcactiuser ping") //修改对应数据库路径,用户名和密码
If Instr(str1,"alive") > 0Then
WScript.Echo 1
Else
WScript.Echo 0
End If
Function getCommandOutput(theCommand)
Dim objShell, objCmdExec
Set objShell =CreateObject("WScript.Shell")
Set objCmdExec = objshell.exec(thecommand)
getCommandOutput =objCmdExec.StdOut.ReadAll
end FunctionMYSQL-status.vbs
Set objFS = CreateObject("Scripting.FileSystemObject")
Set objArgs = WScript.Arguments
str1 = getCommandOutput("D:\SOFT_PHP_PACKAGE\mysql\bin\mysqladmin-u cactiuser -pcactiuser extended-status") //修改对应数据库路径,用户名和密码
Arg = objArgs(0)
str2 = Split(str1,"|")
For i = LBound(str2) to UBound(str2)
If Trim(str2(i)) = Arg Then
WScript.Echo TRIM(str2(i+1))
Exit For
End If
next
Function getCommandOutput(theCommand)
Dim objShell, objCmdExec
Set objShell =CreateObject("WScript.Shell")
Set objCmdExec = objshell.exec(thecommand)
getCommandOutput =objCmdExec.StdOut.ReadAll
end Function2)修改windows上的zabbix_agentd.comf文件,设置key值。在UserParameter下面加两句;
UserParameter=mysql.status[*], cscript/nologo d:\Zabbix\Scripts\MySQL_Ext-Status_Script.vbs $1
UserParameter=mysql.ping, cscript /nologo d:\Zabbix\Scripts\MySql_Ping.vbs
3)重启zabbix_agentd,并给主机添加MySQL模版,查看items状态。
