nagios+rrdtool+pnp 分析图表

(2012-04-18 16:13:42)

转载▼

    nagios 对服务或主机监控的是一个瞬时状态，有时候管理员须要了解主机一段时间内的性能及服务的响应状态，而且造成图表，这时就会用到pnp。

    pnp是基于php和perl的，pnp能够利用rrdtool工具将nagios采集的数据绘制成相关的图表，而后显示主机或者服务在一段时间内的运行情况。

    若是要安装pnp，须要安装以下环境：

    1）整合后的apache和php环境，需支持GD、zlib、jpeg

    2）安装rrdtool工具

    3）安装perl

1.安装PNP

    首先安装rrdtool-1.4.5.tar.gz

    ./configure --prefix=/usr/local/rrdtool

    make

    make install

   

    接着安装pnp-0.4.13.tar.gz

    ./configure --with-nagios-user=nagios  --with-nagios-group-nagios --with-rrdtool==/usr/local/rrdtool/bin/rrdtool --with-perfdata-dir=/usr/local/nagios/share/perfdata

    make all

    make install

    make install-config

    make install-init

2.配置PNP

    (1)建立默认配置文件

    cd /usr/local/nagios/etc/pnp

    cp npcd.cfg-sample npcd.cfg

    cp process_perfdata.cfg-sample process_perfdata.cfg

    cp rra.cfg-sample rra.cfg

    chown -R nagios.nagios /usr/local/nagios/etc/pnp

   （2）修改process_perfdata.cfg文件

     LOG_FILE = /usr/local/nagios/var/perfdata.log
     #
     # Loglevel 0=silent 1=normal 2=debug
     #
     LOG_LEVEL = 2

     这里将日志级别改成2，即debug模式

3.修改nagios配置文件

     （1）修改nagios.cfg

       pnp是经过调用nagios的数据来生成图表的，因此须要开启nagios的数据输出功能

       process_performance_data=1    ###开启数据输出功能

       host_perfdata_command=process-host-perfdata
       service_perfdata_command=process-service-perfdata

     （2）修改commands.cfg

      process-host-perfdata和process-service-perfdata指令声明了nagios输出哪些值到输出文件，pnp定义了一个perl脚本process_perfdata.pl，能够将指令中对应的执行命令替换成此脚本

      # '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
        }
     （3）修改hosts.cfg和services.cfg文件

       在hosts.cfg文件中增长如下代码：

       define host {
        name    hosts-pnp
        register        0
        action_url      /nagios/pnp/index.php?host=$HOSTNAME$
        process_perf_data       1
       }

       并给每一个主机增长一句：

       use   hosts-pnp  意思是将hosts-pnp引用

       在services.cfg文件中增长如下代码：

       define service {
        name    services-pnp
        register        0
        action_url      /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
        process_perf_data       1
       }

       并给每一个服务增长一句：

       use   services-pnp  意思是将services-pnp引用

4.测试pnp功能

       重启nagios

       /etc/init.d/nagios  restart

       在目录/usr/local/nagios/share/perfdata下会生成以主机名命名的文件夹

       访问主页，在每一个主机后面会有一个小太阳图标，点击进行就能看见图表了

5.报错修改

     （1）点击小太阳也能会报如下这种错误：

       Warning: date() [function.date]: It is not safe to rely on the system's timezone settings.You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Asia/Chongqing' for 'CST/8.0/no DST' instead in /usr/local/nagios/share/pnp/include/function.inc.php on line 557

Deprecated: Function eregi() is deprecated in /usr/local/nagios/share/pnp/include/function.inc.php on line 1541

Deprecated: Function eregi() is deprecated in /usr/local/nagios/share/pnp/include/function.inc.php on line 1541

Deprecated: Function eregi() is deprecated in /usr/local/nagios/share/pnp/include/function.inc.php on line 1541

        这是由于pnp-0.4.14对PHP 5.3.0的支持还不是很好，其中有几个bug须要修改：

        根据错误提示打开

        vi /usr/local/nagios/share/pnp/include/function.inc.php

        找到行1541附近修改成

        if($level == 2 && $type == "complete" && preg_match("/^NAGIOS_/",$tag)){

        还会有两处错误须要修改，根据提示找到对应行进行修改：

        line 556: 添加：date_default_timezone_set('UTC');
        line 1033：修改成$pdf = new PDF('P', 'mm', 'A4'); 删除&

 

        再从新重启nagios，应该就能看到图表了

 

            (2) 安装rrdtool时会报错

                  configure: error: Please fix the library issues listed above and try again.

                  须要安装rpm包：

                    cairo-1.2.4-5.el5.i386.rpm

                    cairo-devel-1.2.4-5.el5.i386.rpm

                    pango-1.14.9-6.el5.centos.i386.rpm             

                    pango-devel-1.14.9-6.el5.centos.i386.rpm

 

 

终于搞定搞定，中间安装的时候还报了不少次错误，大部分都是你的包没有装彻底，只要按照错误提示把相应的包安装好就OK了，先确认是否有如下rpm包：

   rpm -qa |grep zlib  

        zlib-1.1.4-8

        zlib-devel-1.1.4-8

   rpm -qa |grep libpng 
       libpng-1.2.10-7.1.el5_3.2
       libpng-devel-1.2.10-7.1.el5_3.2  

   rpm -qa |grep freetype
       freetype-2.2.1-21.el5_3
       freetype-devel-2.2.1-21.el5_3

   rpm -qa |grep  libart_lgpl

        libart_lgpl-devel-2.3.17-4
        libart_lgpl-2.3.17-4

----

要实现Nagios数据的图像化须要使用第三方的软件，PNPNagios能够完成这个任务，PNPNagios的原名为php，下载地址为http://sourceforge.net/projects/pnp4nagios/，它利用RRDTool工具将Nagios的数据生成图形，以便更直观的查看，并且能够查看历史记录。

 

PNPNagios的安装与设置

 

若是解决了PNPNagios软件的依赖性，那么它仍是比较好安装的，所以在具体的安装中，首先要根据下面提到的“软件依赖性”安装相关的软件或者模块，而后再安装PNPNagios软件。

软件依赖性

 

    要安装使用pnp4nagios须要如下软件：

 

u       Perl >= 5.x，不须要其它额外的模块；

u       RRDtool >= 1.x，1.2版本更好，可是并不强制使用这个版本；

u       PHP >= 5.1.6 基于Kohana的web前端的须要；

u       Nagios >= 2.x 或者是Icinga；

u       Kohana须要启用“mod_rewrite”模块

 

    注意：安装RRDtool没有安装包管理器可能会致使丢失dejavu字体，若是查看图像没有字体时，那么多是因为这个问题引发的。

 

下载安装

 

首先来安装rrdtool，在这里比较简单的节选了部分安装过程：

 

[root@ff ~]# tar -zxvf rrdtool- 1.2.15 .tar.gz [root@ff ~]# cd rrdtool- 1.2.15 [root@ff rrdtool- 1.2.15 ]# ./configure     ---------------------------------------------------------------- Config is DONE!             With MMAP IO: yes           Perl Modules: perl_piped perl_shared            Perl Binary: /usr/bin/perl           Perl Version: 5.8.5           Perl Options: PREFIX=/usr/local/rrdtool- 1.2.15 LIB=/usr/local/rrdtool-1.2.15/lib/perl/5.8.5     Build Tcl Bindings: yes  Build Python Bindings: yes           Build rrdcgi: yes        Build librrd MT: yes     Type 'make' to compile the software and use 'make install' to install everything to: /usr/local/rrdtool- 1.2.15 .          ... that wishlist is NO JOKE. If you find RRDtool useful make me happy. Go to http://people.ee.ethz.ch/oetiker/wish and place an order.                                  -- Tobi Oetiker <tobi@oetiker.ch> ---------------------------------------------------------------- [root@ff rrdtool- 1.2.15 ]# make [root@ff rrdtool- 1.2.15 ]# make install

 

由于下面的安装中须要rrdtool的安装目录，所以在这里有必要提一下，下面来下载并安装PNP4Nagios。

 

 

点击上面的图标下载最新版本的安装包，下面是命令行的下载：

 

[root@s10 ~]# wget http://jaist.dl.sourceforge.net/project/pnp4nagios/PNP-0.6/pnp4nagios- 0.6.17 .tar.gz --16:03:19--  http://jaist.dl.sourceforge.net/project/pnp4nagios/PNP-0.6/pnp4nagios- 0.6.17 .tar.gz            => `pnp4nagios- 0.6.17 .tar.gz' 正在解析主机 jaist.dl.sourceforge.net... 150.65.7.130 正在链接 jaist.dl.sourceforge.net[150.65.7.130]:80... 已链接。 已发出 HTTP 请求，正在等待回应... 200 OK 长度：3,006,338 [application/x-gzip]   100%[===========================>] 3,006,338    709.85K/s    ETA 00:00   16:03:25 (649.88 KB/s) - `pnp4nagios- 0.6.17 .tar.gz' saved [3,006,338/3,006,338]   [root@s10 ~]#

 

解压安装包：

 

[root@ff ~]# tar -zxvf pnp4nagios- 0.6.17 .tar.gz [root@ff ~]# cd pnp4nagios- 0.6.17

 

    执行configure：

 

[root@ff pnp4nagios- 0.6.17 ]#  ./configure --prefix=/usr/local/pnp4nagios --with-rrdtool=/usr/local/rrdtool-1.2.15/bin/rrdtool   *** Configuration summary for pnp4nagios-0.6.17 03-25-2012 ***     General Options:   -------------------------         -------------------   Nagios user/group:                nagios nagios   Install directory:                /usr/local/pnp4nagios   HTML Dir:                         /usr/local/pnp4nagios/share   Config Dir:                       /usr/local/pnp4nagios/etc   Location of rrdtool binary:    /usr/local/rrdtool- 1.2.15 /bin/rrdtool Version 1.2.15   RRDs Perl Modules:                *** NOT FOUND ***   RRD Files stored in:              /usr/local/pnp4nagios/var/perfdata   process_perfdata.pl Logfile:      /usr/local/pnp4nagios/var/perfdata.log   Perfdata files (NPCD) stored in:  /usr/local/pnp4nagios/var/spool     Web Interface Options:   -------------------------         -------------------   HTML URL:                         http://localhost/pnp4nagios   Apache Config File:               /etc/httpd/conf.d/pnp4nagios.conf       Review the options above for accuracy.  If they look okay,   type 'make all' to compile.       WARNING: The RRDs Perl Modules are not found on your system            Using RRDs will speedup things in larger installations.

   

注意提示，这个错误的缘由是没有找到RRD perl模块，查看RRDTool的安装包，确实是在下面的路径中存在：

 

[root@ff ~]# ll /usr/local/rrdtool- 1.2.15 /lib/perl/5.8.5/i386-linux-thread-multi/ total 16 -r--r--r--  1 root root 3850 Jul 14  2006 RRDs.pm drwxr-xr-x  4 root root 4096 Jun  8 16:34 auto -r--r--r--  1 root root 1215 Jul 14  2006 ntmake.pl -rw-r--r--  1 root root  456 Jun  8 16:34 perllocal.pod [root@ff ~]#

   

    解决方法使用--with-perl_lib_path选项：
