zabbix监控mysql(perl)
1.yum install perl-libwww-perl
yum install perl-File-Which
yum install perl-DBD-MySQL
yum install perl-Digest-SHA1
yum install perl-Time-HiRes
yum install perl-Crypt-SSLeay
2.测试
#!/usr/bin/perl -w
use DBI;
my $database = "mysql";
my $hostname = "localhost";
my $data_source = "DBI:mysql:$database:$hostname";
my $username = "root";
my $password = "123";
my $dbh = DBI->connect( $data_source,$username,$password)
or die "Cant connect to $data_source";
perl test测试成功
3.在zabbix server端导入监控模板 （13个模版）
Template_FromDual.MySQL.mpm.xml –>(必须)
Template_FromDual.MySQL.server.xml –>监控与数据库相关的Linux服务器性能模板
Template_FromDual.MySQL.process.xml –>监控各种Linux进程
Template_FromDual.MySQL.mysql.xml –>监控Mysql的常用状态变量
Template_FromDual.MySQL.myisam.xml –>监控Myisam存储引擎状态变量
Template_FromDual.MySQL.innodb.xml –>监控Innodb存储引擎状态变量
Template_FromDual.MySQL.master.xml –>监控Mysql Master状态
Template_FromDual.MySQL.slave.xml –>监控Mysql Slave状态
4.agentd
mkdir -p /usr/local/mpm
mv mysql_performance_monitor_agent-0.9 /usr/local/mpm/
cp /usr/local/mpm/etc/FromDualMySQLagent.conf.template /etc/zabbix_mpm.conf
chown zabbix /etc/zabbix_mpm.conf
#mkdir /var/log/zabbix
#touch /var/log/zabbix/FromDualMySQLagent.log
#chown -R zabbix:zabbix /var/log/zabbix
vim/usr/local/etc/zabbix_agentd.conf
UserParameter=FromDual.MySQL.check,/usr/local/mpm/FromDualMySQLagent.pl /etc/zabbix_mpm.conf
5.配置
mpm支持监控多个实例
设置三个级别defaut-->host-->instanc
vim /etc/zabbix_mpm.conf
Type = mysqld
Debug = 2
LogFile = /tmp/FromDualMySQLagent.log
# Information for MySQL connections:
Username = root
Password = 123
MysqlHost = localhost
MysqlPort = 3306
Modules = process mysql myisam innodb
# Zabbix Server IP address
ZabbixServer = X.X.X.X
#下面的主机名需要跟Zabbix Server里面定义的主机名一致
Type = mysqld
Modules = mpm server process mysql myisam innodb
# This MUST match Hostname in Zabbix!
Type = mysqld
MysqlPort = 3306
Modules = process mysql myisam slave innodb master mpm server
PidFile = /data/mysql/log/mysql.pid
修改FromDualMySQLagent.pl脚本里面的zabbix_sender路径：
# This is needed to find zabbix_sender!
$ENV{PATH} .= $ENV{PATH} . ‘:/usr/local/bin’; #将/usr/local/bin修改为zabbix_sender路径
chmod 755chown zabbix:zabbix/usr/local/bin/zabbix_sender
