zabbix agent2 监控oracle数据库的方法

概述

在zabbix5.0版本以上，新增了一个特性，那就是zabbix-agent2，这个是zabbix公司使用go语言重写的一个代理，可以完全替代原来的zabbix-agent。这个代理功能比原来的要强大的多，内置了很多个插件支持对基础资源的监控。这里我选用oracle的插件，来看看zabbix-agent2可以支持监控哪些指标。

安装

安装zabbix-agent2 这里采用zabbix提供的官方repo，进行安装

				?

									rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm

									yum insall -y zabbix-agent2

配置/etc/zabbix/zabbix_agent2.conf文件，修改Server属性值，运行zabbix服务器对其进行轮询取数安装oracleInstant 这里也是采用oracle提供的oracleInstant包进行安装

				?

									rpm -ivh https://download.oracle.com/otn_software/linux/instantclient/211000/oracle-instantclient-basic-21.1.0.0.0-1.x86_64.rpm

设置oracle环境变量

				?

									ORACLE_HOME=/usr/lib/oracle/21/client64;export ORACLE_HOME

									LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib64:$LD_LIBRARY_PATH;export LD_LIBRARY_PATH

配置oracle监控账户

创建oracle监控账号以及授权

				?

									CREATE USER zabbix_mon IDENTIFIED BY zabbix_pass;

									-- Grant access to the zabbix_mon user.

									GRANT CONNECT, CREATE SESSION TO zabbix_mon;

									GRANT SELECT ON DBA_TABLESPACE_USAGE_METRICS TO zabbix_mon;

									GRANT SELECT ON DBA_TABLESPACES TO zabbix_mon;

									GRANT SELECT ON DBA_USERS TO zabbix_mon;

									GRANT SELECT ON DBA_DATA_FILES TO zabbix_mon;

									GRANT SELECT ON DBA_FREE_SPACE TO zabbix_mon;

									GRANT SELECT ON DBA_TEMP_FILES to zabbix_mon;

									GRANT SELECT ON GV_$SORT_SEGMENT to zabbix_mon;

									GRANT SELECT ON V_$ACTIVE_SESSION_HISTORY TO zabbix_mon;

									GRANT SELECT ON V_$ARCHIVE_DEST TO zabbix_mon;

									GRANT SELECT ON V_$ASM_DISKGROUP TO zabbix_mon;

									GRANT SELECT ON V_$DATABASE TO zabbix_mon;

									GRANT SELECT ON V_$DATAFILE TO zabbix_mon;

									GRANT SELECT ON V_$INSTANCE TO zabbix_mon;

									GRANT SELECT ON V_$LOG TO zabbix_mon;

									GRANT SELECT ON V_$OSSTAT TO zabbix_mon;

									GRANT SELECT ON V_$PGASTAT TO zabbix_mon;

									GRANT SELECT ON V_$PARAMETER TO zabbix_mon;

									GRANT SELECT ON V_$PROCESS TO zabbix_mon;

									GRANT SELECT ON V_$RECOVERY_FILE_DEST TO zabbix_mon;

									GRANT SELECT ON V_$RESTORE_POINT TO zabbix_mon;

									GRANT SELECT ON V_$RESTORE_POINT TO zabbix_mon;

									GRANT SELECT ON V_$SESSION TO zabbix_mon;

									GRANT SELECT ON V_$SGASTAT TO zabbix_mon;

									GRANT SELECT ON V_$SYSMETRIC TO zabbix_mon;

									GRANT SELECT ON V_$SYSTEM_PARAMETER TO zabbix_mon;

									GRANT SELECT ON V_$PDBS TO zabbix_mon;

									GRANT SELECT ON V_$SYSTEM_PARAMETER to zabbix_mon;

配置zabbix-agent2配置文件为了方便oracle监控管理，建议使用新的配置文件，放置在/etc/zabbix/zabbix_agent2.d钟，配置内容如下：

				?

									[root@vcenter zabbix_agent2.d]# cat monitor_oracle.conf 

									Plugins.Oracle.Sessions.demo.Uri=tcp://172.20.20.150:1521

									Plugins.Oracle.Sessions.demo.User=zabbix_mon

									Plugins.Oracle.Sessions.demo.Password=zabbix_pass

									Plugins.Oracle.Sessions.demo.Service=demopdb
