ll
cd zabbix-3.4.12
ll
groupadd zabbix
useradd -g zabbix -s /sbin/nologin zabbix
./configure --prefix=/usr/local/zabbix-3.4.12--with-net-snmp --enable-agent
make
make install
cp misc/init.d/tru64/zabbix_agentd/etc/init.d/
chmod +x /etc/init.d/zabbix_agentd
vi /etc/init.d/zabbix_agentd
# chkconfig: 2345 10 90
# description: myservice ....
DAEMON=/usr/local/zabbix-3.4.12/sbin/zabbix_agentd
vim /usr/local/zabbix-3.4.12/etc/zabbix_agentd.conf

/etc/init.d/zabbix_agentd start
chkconfig --add zabbix_agentd
注：libpcre是pcre-devel.x86_64的包含的文件。
安装配置orabbix
Oracle中创建监控用户并赋予权限
grant alter session to zabbix;
grantcreate session to zabbix;
grant connect to zabbix;
alter user zabbix default role all;
grant select on v_$instance to zabbix;
grant select on dba_users to zabbix;
grant select on v_$log_historyto zabbix;
grant select on v_$parameterto zabbix;
grant select on sys.dba_audit_sessionto zabbix;
grant select on v_$lock tozabbix;
grant select on dba_registryto zabbix;
grant select onv_$librarycache to zabbix;
grant select on v_$sysstat tozabbix;
grant select on v_$parameterto zabbix;
grant select on v_$latch to zabbix;
grant select on v_$pgastat tozabbix;
grant select on v_$sgastat tozabbix;
grant select onv_$librarycache to zabbix;
grant select on v_$process tozabbix;
grant select on dba_data_filesto zabbix;
grant select on dba_temp_filesto zabbix;
grant select on dba_free_spaceto zabbix;
grant select onv_$system_event to zabbix;
grant select ondba_tablespaces to zabbix;
grant select on v_$session to zabbix;
grant select on dba_objects tozabbix;
grant select onv_$locked_object to zabbix;
grant select on v_$log tozabbix;
ACL：
dbms_network_acl_admin.create_acl(
acl =>'UTL_INADDR.xml',
description =>'utl_inaddr',
principal => 'ZABBIX',
is_grant => TRUE,
privilege => 'resolve'
);
commit;
end;
/
dbms_network_acl_admin.add_privilege (
acl => 'UTL_INADDR.xml',
principal => 'ZABBIX',
is_grant => TRUE,
privilege => 'connect'
);
commit;
end;
/
dbms_network_acl_admin.assign_acl(
acl => 'UTL_INADDR.xml',
host => '*'
);
commit;
end;
/
Zabbix端需要做的配置
安装orabbix

）在/opt创建目录创建orabbix文件。(原因：orabbix启动文件默认写在/opt/orabbix目录下，也可以修改一下orabbix启动脚本的路径)
#mkdir /opt/orabbix
#mv orabbix-1.2.3.zip /opt/orabbix
#cd /opt/orabbit
#unzip orabbix-1.2.3.zip
授予文件可执行的权限
#chmod a+x /opt/orabbix -R
创建一个名为config.props文件，有模板可以参考。
#cp /opt/orabbix/conf/config.props.sample config.props
修改confi.props配置文件，仅需修改如下内容即可。
# cat /opt/orabbix/conf/config.props |grep-v "#" 这里仅取没有注释的。

t.tablespace_name = s.tablespace(+) \
order by 8) \
where kperc >60 \
and tipo <>'T' \
and tipo <>'U'
如上修改kperc > 60，也就是使用率达到60%以上
