这几项的监控相对比较简单:
客户端:
1 安装支持包
2 赋予脚本权限
3 添加脚本命令到nrpe,并重启nrpe.
服务端:
1 添加监控命令check_iostat
2 在对应的服务配置文件里增加监控项目并且设置阀值
3 让nagios重读配置文件。
---------------客户端配置-----------------
Nagios-Plugin-0.31.tar.gz
Params-Validate-0.91.tar.gz
Math-Calc-Units-1.06.tar.gz
Regexp-Common-2.122.tar.gz
下载后,解压安装:
perl Makefile.PL make make installfu
2 赋予脚本权限:
mv /opt/src/check_io/check_iostat /usr/local/nagios/libexec/ dos2unix /usr/local/nagios/libexec/check_iostat
chmod 755 /usr/local/nagios/libexec/check_iostat chown nagios.nagios /usr/local/nagios/libexec/check_iostat
3 添加脚本命令到nrpe,并重启nrpe:
vim /usr/local/nagios/etc/nrpe.cfg 在文件里添加如下: command[check_io]=/usr/local/nagios/libexec/check_iostat
重启nrpe,由于我的是在xinetd 里面所以和大家的可能有出入。
我的: service xinetd restart
--------------服务端配置----------
1 添加监控命令check_iostat:
vim /usr/local/nagios/etc/objects/commands.cfg
#check_iostat define command{ command_name check_iostat command_line $USER1$/check_iostat -w $ARG1$ -c $ARG2$ }
2 在对应的服务配置文件里增加监控项目并且设置阀值
define service{ use generic-service host_name 被控服务器的IP service_description 9.Check_IO check_command check_nrpe!check_iostat!100!200 }
3 让nagios重读配置文件。
service nagios reload
-------------测试部分-----------------
本地:
[root@localhost iostat]# /usr/local/nagios/libexec/check_iostat IOSTAT OK - user 1.62 nice 0.00 sys 0.31 iowait 0.08 idle 0.00 | iowait=0.08%;; idle=0.00%;; user=1.62%;; nice=0.00%;; sys=0.31%;;
nrpe远程:
[root@localhost iostat]# /usr/local/nagios/libexec/check_nrpe -H 10.2.0.16 -c check_iostat IOSTAT OK - user 0.06 nice 0.00 sys 0.03 iowait 0.01 idle 0.00 | iowait=0.01%;; idle=0.00%;; user=0.06%;; nice=0.00%;; sys=0.03%;;
在来看看 nagios 的web界面
看到了把,已经出现了,我们需要的项目。
附件里面带了check_mysql,check_mem,两个监控插件,安装方法一样
--------------------------------------------------------------------------
安装软件太麻烦了,写个小脚本帮助自己减少工作量:
#!/bin/bash yum install -y perl-dev* perl-CPAN tar -zxvf Nagios-Plugin-0.31.tar.gz cd Nagios-Plugin-0.31 perl Makefile.PL make && make install cd .. tar -zxvf Params-Validate-0.91.tar.gz cd Params-Validate-0.91 perl Makefile.PL make && make install cd .. tar -zxvf Math-Calc-Units-1.06.tar.gz cd Math-Calc-Units-1.06 perl Makefile.PL make && make install cd .. tar -zxvf Regexp-Common-2.122.tar.gz cd Regexp-Common-2.122 perl Makefile.PL make && make install cd .. tar -zxvf Class-Accessor-0.31.tar.gz cd Class-Accessor-0.31 perl Makefile.PL make && make install cd .. tar -zxvf Config-Tiny-2.12.tar.gz cd Config-Tiny-2.12 perl Makefile.PL make && make install cd .. mv /opt/src/check_io/check_iostat /usr/local/nagios/libexec/ dos2unix /usr/local/nagios/libexec/check_iostat chmod 755 /usr/local/nagios/libexec/check_iostat chown nagios.nagios /usr/local/nagios/libexec/check_iostat
这是安装时用到的所有软件
check_iostat 所有的软件包
