nagios報 check_oracle_rman_backup_problems警示處理思路

標籤：check_oracle_rman_b

本人不是Oracle DBA，不懂Oracle，警示了營運又不管，說是DBA的活，反正在他們眼裡無論是MySQL，Oracle,SYBASE還是Redis，MongoDB都是DBA，和他們沒關係。。。。。
1.開啟nrpe.cfg，找到check_oracle_rman_backup_problems監控項，執行一下
cat /usr/local/nagios/etc/nrpe.cfgbr/>
2.找到check_oracle_health指令碼（perl語言）監控的，那就開啟看看是如何取值監控的唄
通過rman-backup-problems搜尋到在@mode數組
並找到如下代碼，其中sql就是我們最終要找的，這是關於rman備份狀態監控
elsif ($params{mode} =~ /server::instance::rman::backup::problems/) {
$self->{rman_backup_problems} = $self->{handle}->fetchrow_array(q{
SELECT COUNT(*) FROM v$rman_status
WHERE
operation = ‘BACKUP‘
AND
status != ‘COMPLETED‘
AND
status != ‘RUNNING‘
AND
start_time > sysdate-3
});
} elsif ($params{mode} =~ /server::instance::rman::backup::problems/) {
$self->add_nagios(
$self->check_thresholds($self->{rman_backup_problems}, 1, 2),
sprintf "rman had %d problems during the last 3 days",
$self->{rman_backup_problems});
$self->add_perfdata(sprintf "rman_backup_problems=%d;%d;%d",
$self->{rman_backup_problems},
$self->{warningrange}, $self->{criticalrange});
現在知道這個是由於rman備份造成，那就執行下sql和備份日誌，發現如下錯誤
Deleting the following obsolete backups and copies:
Type Key Completion Time Filename/Handle

Control File Copy 69 2017-12-20 11:22:41 /data/ora11g/product/11.2.0/db_1/dbs/snapcf_oradb2.f
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of delete command on ORA_DISK_1 channel at 03/06/2018 01:15:28
ORA-19606: Cannot copy or restore to snapshot control file
知道錯誤，那就好解決啦，網上一搜總結如下：
CONFIGURE SNAPSHOT CONTROLFILE NAME TO ‘/data/ora11g/product/11.2.0/db_1/dbs/snapcf_oradb2.f_bak‘;
crosscheck controlfilecopy ‘/data/ora11g/product/11.2.0/db_1/dbs/snapcf_oradb2.f‘;
delete expired controlfilecopy ‘/data/ora11g/product/11.2.0/db_1/dbs/snapcf_oradb2.f‘;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO ‘/data/ora11g/product/11.2.0/db_1/dbs/snapcf_oradb2.f‘;
CONFIGURE SNAPSHOT CONTROLFILE NAME clear;
總結，這裡需要你能看懂perl物件導向編程，這裡package xxx相當於class 聲明類，new函數就是常說的建構函式，我覺的不會不可怕，不會可以去學，順便瞭解了一下perl語言，還是有收穫的
