使用NDOUtils将Nagios监控信息存入MySQL

使用NDOUtils将Nagios监控信息存入MySQL

1.NDOUtils安装需求

nagios mysql cpan DBI #非必需 cpan DBD::mysql #非必需

2.关联mysql头文件和库 不做关联可能在config或make时出错

1. ln -s /opt/mysql/include/* /usr/include/
2. ln -s /opt/mysql/lib/* /usr/lib/
3. echo '/usr/lib' >> /etc/ld.so.conf
4. ldconfig -v

3.安装ndoutils

http://sourceforge.net/project/showfiles.php?group_id=26589

1. wget -c http://nchc.dl.sourceforge.net/sourceforge/nagios/ndoutils-1.4b7.tar.gz
2. tar zxvf ndoutils-1.4b7.tar.gz
3. cd ndoutils-1.4b7
4. ./configure --prefix=/usr/local/nagios --enable-mysql --disable-pgsql LDFLAGS=-L/opt/mysql/lib --with-mysql-inc=/opt/mysql/include/mysql --with-mysql-lib=/opt/mysql/lib/mysql

*config时使用以下mysql参数

1. --with-mysql-inc=/opt/mysql/include --with-mysql-lib=/opt/mysql/lib
2. #config成功
3. #make出错

*config时使用以下mysql参数

1. --with-mysql-inc=/opt/mysql/include/mysql --with-mysql-lib=/opt/mysql/lib/mysql
2. #config出错
3. #make成功并生成文件
4. #启动ndo2db会出错

*没有LDFLAGS=-L/opt/mysql/lib

1. <del datetime="2009-05-27T06:58:24+00:00">LDFLAGS=-L/opt/mysql/lib </del>
2. #ndo2db不能导入到数据库

相关错误

1. In file included from io.c:10:
2. ../include/config.h:261:25: mysql/mysql.h: 没有那个文件或目录
3. ../include/config.h:262:26: mysql/errmsg.h: 没有那个文件或目录
4. make[1]: *** [io.o] 错误 1
5. checking for mysql/mysql.h... no
7. *** MySQL include file could not be located... **********************
9. You chose to compile NDBXT with MySQL support, but I was unable to
10. locate on your system. If the include file is
11. installed, use the --with-mysql-inc argument to specify the location
12. of the MySQL include file.
13. make
14. ll ./src

看看是否有以下文件 ndo2db-2x ndo2db-3x ndomod-2x.o ndomod-3x.o

4.拷贝文件 #　我的Nagios是3.0.6，所以拷贝的是ndomod-3x.o、ndo2db-3x，如果你的是2.X.x请拷贝ndomod-2x.o、ndo2db-2x

1. cp ./src/ndomod-3x.o /usr/local/nagios/bin
2. cp ./src/ndo2db-3x /usr/local/nagios/bin
3. cp ./src/log2ndo /usr/local/nagios/bin
4. cp ./src/file2sock /usr/local/nagios/bin
5. chown nagios:nagios /usr/local/nagios/bin/*

5.拷贝配置文件

1. cp ./config/ndo* /usr/local/nagios/etc/
2. chown nagios:nagios /usr/local/nagios/etc/*

6.创建ndo的mysql 数据库及用户

1. CREATEDATABASE`nagios`DEFAULTCHARACTERSETutf8COLLATEutf8_general_ci;
2. GRANT select,insert,update,deleteONnagios.* TOnagiosndo@localhostidentifiedby'password123';
3. FLUSH PRIVILEGES ;

7.导入数据库结构 使用db/installdb脚本 需要以下支持

cpan DBI cpan DBD::mysql

1. cd ./db/
2. ./installdb -u root -p 123456 -h localhost -d nagios

用命令导入(其实和用脚本是一回事,也可以用phpmyadmin来导入)

1. /opt/mysql/bin/mysql -u root -p -D nagios -h localhost < ./db/mysql.sql

输入密码

成功导入59张表

8.修改配置文件 vi /usr/local/nagios/etc/ndo2db.cfg

1. db_user=nagiosndo
2. db_pass=password123

vi /usr/local/nagios/etc/nagios.cfg

1. # 修改下面参数的值为-1（一般默认如此）。
2. event_broker_options=-1
3. # 复制下面内容粘贴到#broker_module＝...下面。
4. # 注意broker_module= 和config_file是在一行上
5. # Uncomment the line below if you're running Nagios 3.x
6. broker_module=/usr/local/nagios/bin/ndomod-3x.o config_file=/usr/local/nagios/etc/ndomod.cfg

9.启动ndo2db

1. /usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg
3. echo 'rm -f /usr/local/nagios/var/ndo.sock' >> /etc/rc.local
4. echo '/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg' >> /etc/rc.local
5. #开机启动
6. Support for the specified database server is either not yet supported, or was not found on your system.
7. /usr/local/nagios/bin/ndo2db-3x: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory

出现以上错误请执行第2步

10.重启动nagios

1. /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
2. service nagios restart

一般情况下到此已完成安装，可以去数据库里看下记录有无增加

11.检查安装是否正确

1. tail -20 /usr/local/nagios/var/nagios.log

[1242971625] ndomod: Successfully flushed 80 queued items to data sink. [1242971625] ndomod: Error writing to data sink! Some output may get lost…

貌似有点问题

先改成输出成文件 #vi ndomod.cfg

1. instance_name=default
2. #output_type=tcpsocket
3. #output=127.0.0.1
5. output_type=file
6. output=/usr/local/nagios/var/ndo.dat
7. service nagios restart

看看有没有/usr/local/nagios/var/ndo.dat文件，ok，发现文件，说明第一步可以生成文件 查看文件内容

1. cd /usr/local/nagios/var/
2. head -30 ndo.dat
4. HELLO
5. PROTOCOL: 2
6. AGENT: NDOMOD
7. AGENTVERSION: 1.4b7
8. STARTTIME: 1243393299
9. DISPOSITION: REALTIME
10. CONNECTION: FILE
11. CONNECTTYPE: INITIAL
12. INSTANCENAME: default
13. STARTDATADUMP
16. 202:
17. 1=300
18. 2=0
19. 3=0
20. 4=1243393292.450675
21. 73=1243393292
22. 74=262144
23. 72=ndomod: Error writing to data sink!  Some output may get lost...
24. 999
28. 201:
29. 1=205
30. 2=0

使用file2sock尝试socket方式

1. ../bin/file2sock -s /usr/local/nagios/var/ndo.dat -d /usr/local/nagios/var/ndo.sock -t unix -p 5668

Error while writing to destination socket: Connection reset by peer

尝试tcp方式 vi ndo2db.cfg

1. #socket_type=unix
2. socket_type=tcp

重新载入ndo2db

1. ps aux|grep ndo2db
2. kill $pid
3. /usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg
5. ../bin/file2sock -s ndo.dat -d localhost -t tcp -p 5668

Error while writing to destination socket: Connection reset by peer

依然不行，重新编译ndoutils并加上 LDFLAGS=-L/opt/mysql/lib

1. ./configure --prefix=/usr/local/nagios --enable-mysql --disable-pgsql LDFLAGS=-L/opt/mysql/lib --with-mysql-inc=/opt/mysql/include/mysql --with-mysql-lib=/opt/mysql/lib/mysql
2. make
3. #再执行一下安装过程后，通过

================= 200912-07 更新

tail /var/log/messages

1. Dec  7 14:09:13 localhost nagios: ndomod: Still unable to connect to data sink.  10547 items lost, 5000 queued items to flush.
2. Dec  7 14:09:29 localhost nagios: ndomod: Still unable to connect to data sink.  10746 items lost, 5000 queued items to flush.

连接不到mysql,重启一下

/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg

1. Could not bind socket: Address already in use

ps aux|grep ndo2db 没有

查看套接字文件是否存在,删除之 ll /usr/local/nagios/var/ndo.sock rm /usr/local/nagios/var/ndo.sock

重启 /usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg

tail /var/log/messages

1. Dec  7 14:09:45 localhost nagios: ndomod: Successfully connected to data sink.  10861 items lost, 5000 queued items to flush.
2. Dec  7 14:09:45 localhost nagios: ndomod: Successfully flushed 5000 queued items to data sink.
3. Dec  7 14:09:45 localhost ndo2db-3x: Successfully connected to MySQL database
