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
- ln -s /opt/mysql/include/* /usr/include/
- ln -s /opt/mysql/lib/* /usr/lib/
- echo '/usr/lib' >> /etc/ld.so.conf
- ldconfig -v
3.安装ndoutils
http://sourceforge.net/project/showfiles.php?group_id=26589
- wget -c http://nchc.dl.sourceforge.net/sourceforge/nagios/ndoutils-1.4b7.tar.gz
- tar zxvf ndoutils-1.4b7.tar.gz
- cd ndoutils-1.4b7
- ./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
- --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
- --with-mysql-inc=/opt/mysql/include/mysql --with-mysql-lib=/opt/mysql/lib/mysql
- #config出错
- #make成功并生成文件
- #启动ndo2db会出错
*没有LDFLAGS=-L/opt/mysql/lib
- <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
- In file included from io.c:10:
- ../include/config.h:261:25: mysql/mysql.h: 没有那个文件或目录
- ../include/config.h:262:26: mysql/errmsg.h: 没有那个文件或目录
- make[1]: *** [io.o] 错误 1
- checking for mysql/mysql.h... no
- *** MySQL include file could not be located... **********************
- You chose to compile NDBXT with MySQL support, but I was unable to
- locate on your system. If the include file is
- installed, use the --with-mysql-inc argument to specify the location
- of the MySQL include file.
- 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 ./src/ndomod-3x.o /usr/local/nagios/bin
- cp ./src/ndo2db-3x /usr/local/nagios/bin
- cp ./src/log2ndo /usr/local/nagios/bin
- cp ./src/file2sock /usr/local/nagios/bin
- chown nagios:nagios /usr/local/nagios/bin/*
5.拷贝配置文件
- 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
- CREATEDATABASE`nagios`DEFAULTCHARACTERSETutf8COLLATEutf8_general_ci;
- GRANT select,insert,update,deleteONnagios.* TOnagiosndo@localhostidentifiedby'password123';
- 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
- 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)
- /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
- db_user=nagiosndo
- db_pass=password123
vi /usr/local/nagios/etc/nagios.cfg
- # 修改下面参数的值为-1（一般默认如此）。
- event_broker_options=-1
- # 复制下面内容粘贴到#broker_module＝...下面。
- # 注意broker_module= 和config_file是在一行上
- # Uncomment the line below if you're running Nagios 3.x
- broker_module=/usr/local/nagios/bin/ndomod-3x.o config_file=/usr/local/nagios/etc/ndomod.cfg
9.启动ndo2db
- /usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg
- echo 'rm -f /usr/local/nagios/var/ndo.sock' >> /etc/rc.local
- echo '/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg' >> /etc/rc.local
- #开机启动
- Support for the specified database server is either not yet supported, or was not found on your system.
- /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
- /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
- 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
- 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
- instance_name=default
- #output_type=tcpsocket
- #output=127.0.0.1
- output_type=file
- output=/usr/local/nagios/var/ndo.dat
- 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
- cd /usr/local/nagios/var/
- head -30 ndo.dat
- HELLO
- PROTOCOL: 2
- AGENT: NDOMOD
- AGENTVERSION: 1.4b7
- STARTTIME: 1243393299
- DISPOSITION: REALTIME
- CONNECTION: FILE
- CONNECTTYPE: INITIAL
- INSTANCENAME: default
- STARTDATADUMP
- 202:
- 1=300
- 2=0
- 3=0
- 4=1243393292.450675
- 73=1243393292
- 74=262144
- 72=ndomod: Error writing to data sink! Some output may get lost...
- 999
- 201:
- 1=205
- 2=0
使用file2sock尝试socket方式
- ../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
- #socket_type=unix
- socket_type=tcp
��新载入ndo2db
- 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
- ./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
- make
- #再执行一下安装过程后，通过
=================
200912-07 更新
tail /var/log/messages
- 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
- 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
- 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
