nrpe安装脚本

nagios-plugins-1.4.13.tar.gz
nrpe-2.8.tar.gz
源码包文件提前下载好

[root@dd]more install.sh 
#!/bin/bash
tar -xvzf nagios-plugins-1.4.13.tar.gz
cd nagios-plugins-1.4.13
./configure
make
make install
groupadd nagios
useradd -g nagios -s /sbin/nologin nagios
echo !@NA#$gI%o^S | passwd nagios --stdin
cd ..
tar -xvzf nrpe-2.8.tar.gz
cd nrpe-2.8
./configure
make all
make install-plugin
make install-daemon
make install-daemon-config
echo "OK!"
[root@dd]

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

###参考如下文档做alert 日志监控
 
http://www.adp-gmbh.ch/ora/admin/scripts/read_alert_log.html

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 (
alert_date date,
alert_text varchar2(&&alert_length)
)
storage (initial 512k next 512K pctincrease 0); create index alert_log_idx on alert_log(alert_date)
storage (initial 512k next 512K pctincrease 0); column db new_value _DB noprint;
column bdump new_value _bdump noprint; select instance_name db from v$instance; select value bdump from v$parameter
where name ='background_dump_dest'; drop directory BDUMP;
create directory BDUMP as '&&_bdump'; drop table alert_log_disk; create table alert_log_disk ( text varchar2(&&alert_length) )
organization external (
type oracle_loader
default directory BDUMP
access parameters (
records delimited by newline nologfile nobadfile
fields terminated by "&" ltrim
)
location('alert_&&_DB..log')
)
reject limit unlimited;

update_alert_log.sql

Now, 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

rows_inserted number := 0; alert_date date;

select max(alert_date) into max_date from alert_log; if (max_date is null) then
max_date := to_date('01-jan-1980', 'dd-mon-yyyy');
end if; for r in (

)
loop isdate := 0;
alert_text := null; select count(*) into isdate
from dual
where substr(r.text, 21) in ('2003','2004','2005','2006','2007')
and r.text not like '%cycle_run_year%'; if (isdate = 1) then select to_date(substr(r.text, 5),'Mon dd hh24:mi:ss rrrr')
into alert_date
from dual; if (alert_date > max_date) then
start_updating := 1;
end if; else
alert_text := r.text;
end if; if (alert_text is not null) and (start_updating = 1) then insert into alert_log values (alert_date, substr(alert_text, 1, 180));
rows_inserted := rows_inserted + 1;
commit; end if; end loop; sys.dbms_output.put_line('Inserting after date '||to_char(max_date, 'MM/DD/RR HH24:MI:SS'));
sys.dbms_output.put_line('Rows Inserted: '||rows_inserted); commit; end;

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.
