Nagios的性能分析
作者：lz1130
Nagios的性能分析：Nagios的功能是監(jiān)控服務(wù)和主機(jī)，提供了友好的WEB界面查看當(dāng)前的網(wǎng)絡(luò)狀態(tài)、通知和故障歷史、日志文件…但是他自身并不包括這部分功能的代碼，所有的監(jiān)控、檢測(cè)功能都是有插件來完成的。本文講述的是Nagios的性能分析
Nagios性能分析
監(jiān)控服務(wù)變化曲線的工具 ---- PNP
安裝rrdtools(繪圖工具)可能需要的庫
- yum install cairo pango libart_lgpl libart_lgpl-devel zlib zlib-devel freetype freetype-devel
- yum install cairo pango libart_lgpl libart_lgpl-devel zlib zlib-devel freetype freetype-devel
安裝rrdtools
- ./configure
- make
- make install
- ./configure
- make
- make install
編輯nagios.cfg，Nagios 的主配置文件
- vi /usr/local/nagios/etc/nagios.cfg
修改如下：
- process_performance_data=1
- hosthost_perfdata_command=host-service-perfdata
- service_perfdata_command=process-service-perfdata
- vi /usr/local/nagios/etc/nagios.cfg
修改如下：
- process_performance_data=1
- hosthost_perfdata_command=host-service-perfdata
- service_perfdata_command=process-service-perfdata
如果想要對(duì)某個(gè)監(jiān)控對(duì)象做數(shù)據(jù)圖表，則需在所對(duì)應(yīng)的host或者service 定義中包含如下的定義：
- process_perf_data 1
編輯command.cfg，將“process-service-perfdata”命令對(duì)應(yīng)的執(zhí)行命令行的內(nèi)容替換成該腳本：
- define command{
- command_name process-service-perfdata
- # command_line /usr/bin/printf "%b" "$LASTSERVICECHECK$\t$HOSTNAME$\t$SERVICEDESC$\t$SERVICESTATE$\t$SERVICEATTEMPT$\t$SERV
- ICESTATETYPE$\t$SERVICEEXECUTIONTIME$\t$SERVICELATENCY$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$\n" >> /usr/local/nagios/var/service-perf
- data.out
- command_line /usr/local/nagios/libexec/process_perfdata.pl
- # command_line /usr/bin/perl /usr/local/nagios/sbin/insert.cgi
- }
- define command{
- command_name process-service-perfdata
- # command_line /usr/bin/printf "%b" "$LASTSERVICECHECK$\t$HOSTNAME$\t$SERVICEDESC$\t$SERVICESTATE$\t$SERVICEATTEMPT$\t$SERV
- ICESTATETYPE$\t$SERVICEEXECUTIONTIME$\t$SERVICELATENCY$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$\n" >> /usr/local/nagios/var/service-perf
- data.out
- command_line /usr/local/nagios/libexec/process_perfdata.pl
- # command_line /usr/bin/perl /usr/local/nagios/sbin/insert.cgi
- }
安裝PNP
- ./configure --with-rrdtool=/usr/local/rrdtool-1.0.50/bin/rrdtool
- make all
- make install
- ./configure --with-rrdtool=/usr/local/rrdtool-1.0.50/bin/rrdtool
- make all
- make install
檢查Nagios配置文件并重啟Nagios
- /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
- /etc/init.d/nagios restart
- /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
- /etc/init.d/nagios restart
