一．安裝rrdtool
rrdtool將nagios採集的資料繪製成圖表。
--with-perl-options=/usr/bin/perl 指定perl路徑
#make
#make install
二．安裝pnp
--with-rrdtool=/usr/local/rrdtool/bin/rrdtool/ 指定rrdtool路徑
--with-perfdata-dir=/usr/local/nagios/share/perfdata/ 指定perfdata存放路徑
general options:
nagios user/group: nagios nagios
install directory: /usr/local/nagios
html dir: /usr/local/nagios/share/pnp
config dir: /usr/local/nagios/etc/pnp
location of rrdtool binary: /usr/local/rrdtool/bin/rrdtool version 1.4.3
rrds perl modules: found (version 1.4003)
rrd files stored in: /usr/local/nagios/share/perfdata/
process_perfdata.pl logfile: /usr/local/nagios/var/perfdata.log
perfdata files (npcd) stored in: /usr/local/nagios/var/spool/perfdata/
#make all
#make install
#make install-config
#make install-init
三．配置nagios
#vi /usr/local/nagios/etc/nagios (在880行左右)
process_performance_data=1 //開啟收集perfdata（預設是關閉的）
host_perfdata_command=process-host-perfdata
service_perfdata_command=process-service-perfdata
#vi /usr/local/nagios/etc/objects/commands.cfg
增加對process-host-perfdata，process-service-perfdata命令的定義
define command{
command_name process-service-perfdata //定義命令名稱
command_line /usr/local/nagios/libexec/process_perfdata.pl //指定命名
define command{
command_name process-service-perfdata
command_line /usr/local/nagios/libexec/process_perfdata.pl
# vi /usr/local/nagios/etc/objects/templates.cfg
新增太陽圖示，配置前端頁面
define service{
name generic-service
process_perf_data 1 //開啟收集perfdata
action_url /nagios/pnp/index.php?host=$hostname$&srv=$servicedesc$ //定義url
define service{
name local-service
use generic-service
action_url /nagios/pnp/index.php?host=$hostname$
process_perf_data 1
# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg 檢測配置
#service nagios restart
四．驗證
