Zabbix实战-简易教程--DB类--Oracle(主从同步、归档备份以及DB备份状态监控)
一、背景需求
由于数据库是整个公司的核心，所以数据完整和备份是重中之重。本文简单阐述oracle主从同步、归档备份以及DB备份状态监控。
二、脚本编写
oracle DB备份状态脚本：
[root@bgp-bjzw-zabbix-server02 rpm]# cat bk_db.sh
#!/bin/bash #. /home/oracle/.bash_profile frq=`sqlplus -silent '/ as sysdba' << EOSQL whenever sqlerror exit sql.sqlcode set pagesize 0 feedback off verify off heading off echo off timing off select case when (mod(trunc(max(end_time))-trunc(min(end_time)),7)=0) then 'W' when (mod(trunc(max(end_time))-trunc(min(end_time)),7)>0) then 'D' end from v\\$rman_status where object_type like 'DB%' and end_time>sysdate-8; exit; EOSQL` frq=${frq: -1} if [ "$frq" == "D" ]; then db_bk=`sqlplus -silent '/ as sysdba' << EOSQL whenever sqlerror exit sql.sqlcode set pagesize 0 feedback off verify off heading off echo off timing off select count(*) from v\\$rman_status where object_type like 'DB%' and status='COMPLETED' and trunc(end_time)=trunc(sysdate); exit; EOSQL` elif [ "$frq" == "W" ]; then db_bk=`sqlplus -silent '/ as sysdba' << EOSQL whenever sqlerror exit sql.sqlcode set pagesize 0 feedback off verify off heading off echo off timing off select count(*) from v\\$rman_status where object_type like 'DB%' and status='COMPLETED' and end_time>sysdate-7; exit; EOSQL` fi db_bk=${db_bk: -1} if [ $db_bk -gt 0 ]; then echo "DB Backup OK" else echo "DB Backup Problem" fi
oracle主从同步状态：
[root@bgp-bjzw-zabbix-server02 rpm]# cat sysnc_status.sh #!/bin/sh for SID in $(ps -fu oracle | grep pmon | grep -v grep | cut -d_ -f3- | sort); do export ORACLE_SID=$SID row=`sqlplus -silent '/ as sysdba' << EOSQL whenever sqlerror exit sql.sqlcode set pagesize 0 feedback off verify off heading off echo off select count(*) from v\\$dataguard_stats where name in ('transport lag', 'apply lag') and value is not null; exit; EOSQL` if [ $row -eq 2 ]; then t_lag=`sqlplus -silent '/ as sysdba' << EOSQL whenever sqlerror exit sql.sqlcode set pagesize 0 feedback off verify off heading off echo off select to_number(substr(value,2,2))*1440+to_number(substr(value,5,2))*60+to_number(substr(value,8,2)) from v\\$dataguard_stats where name ='transport lag'; exit; EOSQL` a_lag=`sqlplus -silent '/ as sysdba' << EOSQL whenever sqlerror exit sql.sqlcode set pagesize 0 feedback off verify off heading off echo off select to_number(substr(value,2,2))*1440+to_number(substr(value,5,2))*60+to_number(substr(value,8,2)) from v\\$dataguard_stats where name ='apply lag'; exit; EOSQL` if [ $t_lag -gt 60 ]; then t_lag=`echo $t_lag|tr -d " "` echo "Problem:$SID Transport Lag $t_lag Minutes" else echo "$SID Archive log transport OK" fi if [ $a_lag -gt 120 ]; then a_lag=`echo $a_lag|tr -d " "` echo "Problem:$SID Standby not Apply Logs for $a_lag Minutes" else echo "$SID Archive log apply OK" fi else echo "Problem:$SID Standby Disconnected from Primary" fi done
oracle 归档备份状态：
[root@bgp-bjzw-zabbix-server02 rpm]# cat bk_arc.sh #!/bin/bash #. /home/oracle/.bash_profile arc_bk=`sqlplus -silent '/ as sysdba' << EOSQL whenever sqlerror exit sql.sqlcode set pagesize 0 feedback off verify off heading off echo off select count(*) from v\\$rman_status where object_type='ARCHIVELOG' and status='COMPLETED' and trunc(end_time)=trunc(sysdate); exit; EOSQL` arc_bk=${arc_bk#*.} if [ $arc_bk -gt 0 ]; then echo "Archivelog Backup OK" else echo "Archivelog Backup Problem" fi
三、自定义key和测试
UserParameter=custom.bkdb.status[*],sudo su - oracle -c /etc/zabbix/externalscripts/bk_db.sh UserParameter=custom.bkarc.status[*],sudo su - oracle -c /etc/zabbix/externalscripts/bk_arc.sh UserParameter=custom.sysnc.status[*],sudo su - oracle -c /etc/zabbix/externalscripts/sysnc_status.sh
测试结果如下：
[root@centos6564-73-131 ~]# zabbix_get -s192.168.72.160 -k custom.bkdb.status DB Backup OK [root@centos6564-73-131 ~]# zabbix_get -s192.168.72.160 -k custom.bkarc.status Archivelog Backup OK [root@centos6564-73-131 ~]# zabbix_get -s192.168.72.160 -k custom.sysnc.status paydbrac1 sync Ok
四、制作模板
模板和上篇监控多表空间汇总到一起，作为监控oracle。

五、触发器设置
六、效果图
