nagios图形监控和管理

1、Pnp安装图形监控曲线（服务器端）

    Pnp出图软件官方站点：http://docs.pnp4nagios.org/

2、执行yum安装基础pnp软件需要依赖的包：

    yum install cairo pango zlib zlib-devel freetype freetype-devel gd dg-devel -y

 

3、安装libart_lgpl 

     tar xf libart_lgpl-2.3.17.tar.gz
     cd libart_lgpl-2.3.17
     ./configure
     make
     make install
     /bin/cp -r /usr/local/include/libart-2.0 /usr/include/
     cd ../
     # 原理：利用rrdtool （轮询数据库工具）出图

4、安装rrdtool

    tar xf rrdtool-1.2.14.tar.gz
    cd rrdtool-1.2.14
    ./configure --prefix=/usr/local/rrdtool --disable-python --disable-ct1

      ##WARNING: The RRDs Perl Modules are not found on your System
      #Using RRDs will speedup things in larger Installtions.
      #configure后出现上面的提示可以不用理会。

    make
    make install
    cd ..

    #关注：ls /usr/local/rrdtool/bin/
            rrdcgi  rrdtool  rrdupdate 表示成功

5、安装负责图形展示的pnp-0.4.14.tar.gz

    tar zxf pnp-0.4.14.tar.gz
    cd pnp-0.4.14
    ./configure \
    --with-rrdtool=/usr/local/rrdtool/bin/rrdtool --with-perfdata-dir=/usr/local/nagios/share/perfdata/

   问题：configure报错（一般不会发生）
    checking for linker flags for loadable modules... -shared
    checking for Perl Module Time::HiRes... no
    configure: error: Perl Module Time::HiRes not available
    解决：yum install perl-Time-HiRes -y

    #################
    #  WARNING: The RRDs Perl Modules are not found on your System
    #           Using RRDs will speedup things in larger Installtions.
    #####################
    make all
    make install
    make install-config
    make install-init
    ll /usr/local/nagios/libexec/ |grep process #（用来搜集数据）

6、出图的配置

    vi nagios.cfg +833

    833 process_performance_data=1   

    #1记录数据，0不记录数据
    837 # HOST AND SERVICE PERFORMANCE DATA PROCESSING COMMANDS
    838 # These commands are run after every host and service check is
    839 # performed.  These commands are executed only if the
    840 # enable_performance_data option (above) is set to 1.  The command
    841 # argument is the short name of a command definition that you
    842 # define in your host configuration file.  Read the HTML docs for
    843 # more information on performance data.
    844
    845 host_perfdata_command=process-host-perfdata

    #主机记录数据

    846 service_perfdata_command=process-service-perfdata
    #服务记录数据

 执行编辑命令 vi /usr/local/nagios/etc/objects/commands.cfg +227，修改commands.cfg配置文件。
    #修改commands.cfg 配置文件，约227-238行
    #默认配置为（如果没有直接添加即可）
    #-----------------------------------------------------------------   
    # 'process-host-perfdata' command definition
    define command{
            command_name    process-host-perfdata
            command_line    /usr/bin/printf "%b"         "$LASTHOSTCHECK$\t$HOSTNAME$\t$HOSTSTATE$\t$HOSTATTEMPT$\t$HOSTSTATETYPE$\t$HOSTEXECUTIONTIME$\t$HOSTOUTPUT$\t$HOSTPERFDAT    A$\n" >> /usr/local/nagios/var/host-perfdata.out
        }
    # 'process-service-perfdata' command definition
    define command{
            command_name    process-service-perfdata
            command_line    /usr/bin/printf "%b"     "$LASTSERVICECHECK$\t$HOSTNAME$\t$SERVICEDESC$\t$SERVICESTATE$\t$SERVICEATTEMPT$\t$SERVICESTATETYPE$\t$SERVICEEXECUTIONTIME$\t$SERVICELATENCY$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$\n" >> /usr/local/nagios/var/service-perfdata.out
        }
    修改成如下配置
    # 'process-host-perfdata' command definition
    define command{
            command_name    process-host-perfdata
            command_line    /usr/local/nagios/libexec/process_perfdata.pl
            }

    # 'process-service-perfdata' command definition
    define command{
            command_name    process-service-perfdata
            command_line    /usr/local/nagios/libexec/process_perfdata.pl
            }
    也可以用nagios变量$USER1$替代/usr/local/nagios/libexec/路径
    执行检查语法命令/etc/init.d/nagios checkconfig
    Total Warnings: 0
    Total Errors:   0
    根据提示，配置通过。重启。

7、   vi  templates.cfg

      58         process_perf_data               1               ; Process performance data

      #出图控制，可以在服务、主机、模版添加；

8、绑定主机出图整合nagios

    define host{
        use                     linux-server
        host_name               nagios
        alias                   nagios-01
        address                 10.0.0.23
        action_url            /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
        }

     #可以在 模版vi templates.cfg 里linux-server里添加

        /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$

       #重启服务后观察主机的监控，如图，点人即可：   

9、绑定服务出图整合nagios

    vi services.cfg
    define service{
        use                      generic-service
        host_name                nagios,C
        service_description      Disk Partition
        check_command            check_nrpe!check_disk
        action_url            /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
     }

10、出图的数据路径：/usr/local/nagios/share/perfdata/

    出图地址：http://10.0.0.22/nagios/pnp/index.php
