nagios安装手记（二）

June 21st, 2009

在nagios安装手记（一）中已经安装好了nagios平台，并且配置了基本的服务，现在继续安装pnp插件以看到可爱的性能图形。

  1. 安装pnp

<pre class=php name=code>./configure –prefix=/usr/local/nm/nagios –with-nagios-user=nm –with-nagios-group=nm –datarootdir=/usr/local/nm/nagios/share/pnp –with-perfdata-dir=/usr/local/nm/nagios/share/perfdata/ make all make install

mkdir /usr/local/nm/nagios/share/perfdata

chown nm:nm /usr/local/nm/nagios/share/perfdata</pre>

  1. 修改nagios配置，生成性能统计数据

<pre class=php name=code># vi nagios/etc/nagios.cfg process_performance_data=1 //修改为1 service_perfdata_command=process-service-perfdata //默认此句被注释掉了

vi nagios/etc/objects/localhost.cfg

define host{ ….. alias localhost process_perf_data 1 //增加此句 address 127.0.0.1 }

vi nagios/etc/objects/commands.cfg

#define command{ //将这个command替换为pnp的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$\t$SERVICEL ATENCY$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$\n” » /usr/local/NSP/nagios/var/service-perfda ta.out

}

define command{ command_name process-service-perfdata command_line /usr/local/NSP/nagios/libexec/process_perfdata.pl }</pre>

  1. 访问pnp的地址http://site/nagios/pnp，如果正常则会显示所监控服务的性能图形，如果异常会显示debug信息。 如果nagios上显示数据正确，而图形显示不正确，可以试试删除nagios/share/perfdata目录下的对应hostname的目录，然后重启nagios。
