nagios报 check_oracle_rman_backup_problems告警处理思路

Posted 2020-10-26

本人不是Oracle DBA，不懂Oracle，告警了运维又不管，说是DBA的活，反正在他们眼里无论是mysql，Oracle,SYBASE还是Redis，MongoDB都是DBA，和他们没关系。。。。。
1.打开nrpe.cfg，找到check_oracle_rman_backup_problems监控项，执行一下
cat /usr/local/nagios/etc/nrpe.cfgbr/>
2.找到check_oracle_health脚本（perl语言）监控的，那就打开看看是如何取值监控的呗
通过rman-backup-problems搜索到在@mode数组

并找到如下代码，其中sql就是我们最终要找的，这是关于rman备份状态监控
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});
现在知道这个是由于rman备份造成，那就执行下sql和备份日志，发现如下错误
Deleting the following obsolete backups and copies:

知道错误，那就好解决啦，网上一搜总结如下：
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;
总结，这里需要你能看懂perl面向对象编程，这里package xxx相当于class 声明类，new函数就是常说的构造函数，我觉的不会不可怕，不会可以去学，顺便了解了一下perl语言，还是有收获的
