Nagios 被动检测oracle Rman备份情况

---

nagios监控服务器ip：192.168.9.172

被监控服务器ip：192.168.9.133
数据库实例名：orcl

需要开通被监控服务器到nagios监控服务器的nsca端口：5667

被监控服务器：
1. 准备Rman脚本rman_orcl.rcv
crosscheck archivelog all;
crosscheck backup;
crosscheck copy;
delete noprompt obsolete;
delete noprompt expired archivelog all;
delete noprompt expired backup;
delete noprompt expired copy;
run{
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
allocate channel c4 type disk;
backup as compressed backupset database format '/backup/rman/orcl_full_%U'
plus archivelog skip inaccessible format '/backup/rman/orcl_ARC_%U';
delete noprompt archivelog all completed before 'sysdate-1';
backup current controlfile format '/backup/rman/grp1_control_bak_%T';
backup spfile format '/backup/rman/grp1_spfile_bak_%T';
release channel c1;
release channel c2;
release channel c3;
release channel c4;
}


2.编辑backup_db的shell脚本backup_db.sh
SIDNAME=orcl
source /home/oracle/prof_orcl
cd /backup/rman

#find /backup/rmanbak/ -name $SIDNAME"_"* -exec rm -rf {} \;
rm /backup/rmanbak/orcl_*

mv /backup/rman/$SIDNAME"_"* /backup/rmanbak/

logName=$SIDNAME"_rman"_`date +'%Y%m%d%H%M%S'`_full.log

cd /backup/rman
rman target / CMDFILE rman_$SIDNAME.rcv >> $logName
##################################
sh check_backup.sh
##################################


3.检查备份情况日志backup_status.log（自动生成）（备份成功）
192.168.9.133    Rman_Backup_GRP1    0    Backup Suess!

4.编辑检查备份情况脚本check_backup.sh
IP=192.168.9.133
SID=orcl

status=`sqlplus  -silent "/as sysdba" < set feedback off
set verify off
set heading off
set echo off
set pagesize 0
SELECT  /*+ rule */ DECODE (
             TRUNC (SYSDATE - start_time),
             0, DECODE (
                   status,
                   'COMPLETED', '0',
                   'COMPLETED WITH WARNINGS','1',
                   '2'),
             '2')
          backup_status
  FROM v\\$rman_backup_job_details
 WHERE start_time = (SELECT MAX (start_time) FROM v\\$rman_backup_job_details);
exit;
eof`
output=`sqlplus  -silent "/as sysdba" < set feedback off
set verify off
set heading off
set echo off
set pagesize 0
SELECT /*+ rule */ DECODE (
          TRUNC (SYSDATE - start_time),
          0, DECODE (status,
                     'COMPLETED', 'Backup Suess!',
                     'COMPLETED WITH WARNINGS', 'Backup With Warnings!',
                     'Backup Failed!'),
          'No Backup!')
          backup_status
  FROM v\\$rman_backup_job_details
 WHERE start_time = (SELECT MAX (start_time) FROM v\\$rman_backup_job_details);
exit;
eof`
hostip=$IP
checkname="Rman_Backup_"$SID

#把rman备份信息写到目录中去
echo -e "$hostip\t$checkname\t$status\t$output" > backup_status.log

#通过nsca方式把backup_status.log的内容传到监控服务器192.168.9.172
/usr/local/nagios/bin/send_nsca 192.168.9.172 -c /usr/local/nagios/etc/send_nsca.cfg < backup_status.log


5.编辑定期运行脚本crontab
[oracle@orcl ~]$ crontab -l
0 22 * * * cd /backup/rman ; sh backup.sh

[oracle@orcl ~]$ cd /backup/rman
[oracle@orcl rman]$ ll
total 520688
