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/
  1. echo '/usr/lib' >> /etc/ld.so.conf
  2. 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
  6.  
  7. *** MySQL include file could not be located... **********************
  8.  
  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.
  1. make
  2. 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
  2.  
  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
  1. Support for the specified database server is either not yet supported, or was not found on your system.
  1. /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
  4.  
  5. output_type=file
  6. output=/usr/local/nagios/var/ndo.dat
  1. 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
  3.  
  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
  14.

  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...

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
  4.  
  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
