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#$gI%o^S | passwd nagios --stdin
cd ..
tar -xvzf nrpe-2.8.tar.gz
cd nrpe-2.8
./configure
make all
make install-plugin
make install-daemon
make install-daemon-config
echo "OK!"
[root@dd]
修改 nrpe文件
vim /usr/local/nagios/etc/nrpe.cfg
#nrpe_user=nagios
nrpe_user=oracle ---以oracle用户运行
allowed_hosts=127.0.0.1,192.169.169.60 --添加监控允许IP
修改check_oracle插件脚本
vim /usr/local/nagios/libexec/check_oracle
添加两行
#! /bin/sh
#
# [email protected]
# 01/06/2000
#
# This Nagios plugin was created to check Oracle status
#
ORACLE_HOME=/opt/oracle/product/10g
PATH=$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
