修改 nrpe文件
vim /usr/local/nagios/etc/nrpe.cfg
#nrpe_user=nagios
nrpe_user=oracle ---以oracle用户运行
allowed_hosts=127.0.0.1,192.169.169.60 --添加监控允许IP
修改check_oracle插件脚本
vim /usr/local/nagios/libexec/check_oracle
添加两行
#! /bin/sh
#
# latigid010@yahoo.com
# 01/06/2000
#
# This Nagios plugin was created to check Oracle status
#
ORACLE_HOME=/opt/oracle/product/10g
PATH=$ORACLE_HOME/bin:$PATH
vim +257 /usr/local/nagios/libexec/check_oracle
257 ON a.tablespace_name=b.tablespace_name WHERE a.tablespace_name=upper('${5}');---方便监控
修改 /usr/local/nagios/etc/nrpe.cfg 文件
。加入以下内容：
#Check Oracle
command[check_oracle_tns]=/usr/local/nagios/libexec/check_oracle –tns orcl
command[check_oracle_db]=/usr/local/nagios/libexec/check_oracle –db orcl
command[check_oracle_login]=/usr/local/nagios/libexec/check_oracle –login orcl c
ommand[check_oracle_cache]=/usr/local/nagios/libexec/check_oracle –cache orcl system lkjsdf 80 90
command[check_oracle_tablespace]=/usr/local/nagios/libexec/check_oracle –tablespace orcl system lkjsdf tab 90 80
具体参数写法请参考 check_oracle –help
二、 配置 nrpe 服务
修改 /usr/local/nagios/etc/nrpe.cfg 文件。加入以下内容：
#Check Oracle
command[check_oracle_tns]=/usr/local/nagios/libexec/check_oracle –tns orcl
command[check_oracle_db]=/usr/local/nagios/libexec/check_oracle –db orcl
command[check_oracle_login]=/usr/local/nagios/libexec/check_oracle –login orcl
command[check_oracle_cache]=/usr/local/nagios/libexec/check_oracle –cache orcl system lkjsdf 80 90
command[check_oracle_tablespace]=/usr/local/nagios/libexec/check_oracle –tablespace orcl system lkjsdf tab 90 80
具体参数写法请参考 check_oracle –help。
配置完成后，重启 xinetd 服务。
三、配置 Nagios 服务端
1.安装 nrpe 脚本支持。—参考官方文档。
2.添加 nrpe 命令配置。修改 nagios/etc/objects/command.cfg 文件：
define command {
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
3.在 nagios/etc/objects 添加oracle 主机配置文件。oracle.cfg 。
define host {
use linux-server
host_name oracle
alias Oracle 10g
address 192.168.100.63
}
define service {
use generic-service
host_name oracle
service_description TNS Check
check_command check_nrpe!check_oracle_tns
}
define service {
use generic-service
host_name oracle
service_description DB Check
check_command check_nrpe!check_oracle_db
}
define service {
use generic-service
host_name oracle
service_description Login Check
check_command check_nrpe!check_oracle_login
}
define service {
use generic-service
host_name oracle
service_description Cache Check
check_command check_nrpe!check_oracle_cache
}
define service {
use generic-service
host_name oracle
service_description Tablespace Check
check_command check_nrpe!check_oracle_tablespace
}
效果图：
NRPE 以及 Nagios-Plugin 安装文件见附件包内。NRPE 官方文档也包含在附件包呢。
备注：
图中 Tablespace check 还没有细调，用了错误的 table 名。
通过修改脚本还可以监视临时表空间。
CRITICAL - ORA-28009: connection as SYS should be as SYSDBA or SYSOPER
[root@dd]/usr/local/nagios/libexec/check_oracle --tablespace duxiu sys oracle USERS 90 80-------勿用sys用户
---------------------------------------------------
监控效果如下
Script to read Oracle's alert log |
||
|
The following script creates two tables: read_alert and read_alert_disk.
read_alert_disk is an external table and contains the content of the alert log.
read_alert will be empty after this script has been executed. It is used by the update_alert_log script, shown further below.
define alert_length="2000" drop table alert_log; create table alert_log ( update_alert_log.sqlNow, after the two tables are created, the alert_log table can be filled with the following script. It only loads those records that are greater than the last time it loaded. And it loads the date/time on every line for convienance. It also helps when the alertlogs get rotated. You still keep the history within an Oracle table. Finally, it also strips out all the «crap» that is really not needed to see if you are looking for errors.
update_alert_log.sql
set serveroutput on declare isdate number := 0; Let's execute the script:
SQL> @update_alert_log Inserting after date 01/01/80 00:00:00 The alert_log table now contains the errors as recorded in the alert.log file:
select alert_date, substr(alert_text,1, 69) 12-JUL-06 Error stack returned to user: ThanksThe scripts above are provided by Shawn M Ellinger.

aintaining Oracle Logs and Diagnostic Files
Prior to version 11g, Oracle databases stored most log and diagnostic information in the $ORACLE_BASE/admin directory. Now in 11g, there is a new directory at $ORACLE_BASE/diagwith a different organizational structure. In either version, it is important to understand what to find in these directories and how to maintain them.
The Admin Directory
In Oracle 10g and earlier, logs and diagnostic information can typically be found in the directory $ORACLE_BASE/admin, but sometimes this admin directory is found in $ORACLE_HOME or is set to another specific location chosen by the administrator. The admin directory typically contains a folder for each database on a system. Within this folder, there are the bdump, cdump and udump directories, among other things.
These directories are populated with diagnostic information by the database. Most of the contents are unique files created by database events, but some files like the alert log are written to on an ongoing basis and will continue to grow if left alone. In either case, these files should occasionally be cleaned up to prevent them from taking up too much disk space.
Checking the Alert Log
The check_alert_log.sh script shown below checks for any ORA- errors in the alert logof a given database. It will take a SID as an argument, or if no SID is specified, it will use the current one if set. In large environments, it may be more desirable to set up a GRID Controller and use that to monitor multiple databases. However, if only a handful of instances need to be monitored, it can be much easier to just set up monitoring scripts like this one.
In order to avoid reporting the same error twice, this script copies the contents out of the alert log, checks for errors and then saves them in a log file by the same name, but with .1 appended to it.
#!/bin/bash
# Add /usr/local/bin to the PATH variable so the oraenv command can be found
PATH=$PATH:/usr/local/bin; export PATH
# If a SID is provided as an argument it will be set and oraenv run
# otherwise we will use the current SID. If no SID is set or provided
# an error message is displayed and the script exits with a status of 1
if [ $1 ]
then
ORACLE_SID=$1
ORAENV_ASK=NO
. oraenv
else
if [ ! $ORACLE_SID ]
then
echo "Error: No ORACLE_SID set or provided as an argument"
exit 1
fi
fi
# Set the ORACLE_BASE variable
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
cd $ORACLE_BASE/admin/$ORACLE_SID/bdump
# Copy the current alert log into a temporary file and empty the original
cp alert_$ORACLE_SID.log alert_$ORACLE_SID.log.temp
cp /dev/null alert_$ORACLE_SID.log
# Check the copy in the temporary file for ORA- errors
grep 'ORA-' alert_$ORACLE_SID.log.temp > /dev/null
# If found, email the Oracle user with the contents of the alert log
if [ $? = 0 ]
then
mail -s "$ORACLE_SID database alert log error" oracle < \
alert_$ORACLE_SID.log.temp
fi
# Move the contents of the temp file onto the permanent copy of the log
# and remove the temp file.
cat alert_$ORACLE_SID.log.temp >> alert_$ORACLE_SID.log.1
rm alert_$ORACLE_SID.log.temp
The block of code which starts with the first if statementis one that will be seen in many of the scripts in this book. If a SID is provided, the $1 variable exists and the oraenv command is executed. If not, the second if statement within the ELSE clause checks to see if a SID has already been set. If it has not, an error message is printed and the script exited with a result code of 1, indicating failure. If this script fails when executed from a crontab, the error message is automatically emailed to the crontab owner.
Since this will likely be run from a crontab entry, you typically provide a SID as an argument. The following crontab entry causes this script to be run every 15 minutes.
