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
echo '/usr/lib' >> /etc/ld.so.conf

ldconfig -v

3.安装ndoutils http://sourceforge.net/project/showfiles.php?group_id=26589 --with-mysql-inc=/opt/mysql/include --with-mysql-lib=/opt/mysql/lib

#config成功

#make出错

*config时使用以下mysql参数
<del datetime="2009-05-27T06:58:24+00:00">LDFLAGS=-L/opt/mysql/lib </del>

#ndo2db不能导入到数据库

相关错误
make

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
cp ./config/ndo* /usr/local/nagios/etc/

chown nagios:nagios /usr/local/nagios/etc/*

6.创建ndo的mysql 数据库及用户
cd ./db/

./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)
db_user=nagiosndo

db_pass=password123

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

echo '/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg' >> /etc/rc.local

#开机启动

/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
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
参考： http://www.nagios.net.cn/blog/blog.php?do-showone-itemid-62-type-blog.html 先改成输出成文件
#vi ndomod.cfg
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
../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
ps aux|grep ndo2db

kill $pid

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

../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
参考 http://www.itnms.net/discuz/viewthread.php?tid=1357&extra=pageD1&page=1 Dec 7 14:09:13 localhost nagios: ndomod: Still unable to connect to data sink. 10547 items lost, 5000 queued items to flush.

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
Dec 7 14:09:45 localhost nagios: ndomod: Successfully connected to data sink. 10861 items lost, 5000 queued items to flush.

Dec 7 14:09:45 localhost nagios: ndomod: Successfully flushed 5000 queued items to data sink.

Dec 7 14:09:45 localhost ndo2db-3x: Successfully connected to MySQL database
