Cacti是一套基于PHP,MySQL,SNMP及RRDTool開發(fā)的網(wǎng)絡流量監(jiān)測圖形分析工具。用來監(jiān)控網(wǎng)絡流量、cpu使用率、內(nèi)存使用率、硬盤使用率等??梢灾庇^的監(jiān)控各種數(shù)據(jù)流量,可以安裝擴展插件,同時支持短信郵件告警等功能。
成都創(chuàng)新互聯(lián)公司:2013年至今為各行業(yè)開拓出企業(yè)自己的“網(wǎng)站建設”服務,為近千家公司企業(yè)提供了專業(yè)的網(wǎng)站設計、網(wǎng)站建設、網(wǎng)頁設計和網(wǎng)站推廣服務, 按需網(wǎng)站制作由設計師親自精心設計,設計的效果完全按照客戶的要求,并適當?shù)奶岢龊侠淼慕ㄗh,擁有的視覺效果,策劃師分析客戶的同行競爭對手,根據(jù)客戶的實際情況給出合理的網(wǎng)站構架,制作客戶同行業(yè)具有領先地位的。
Nagios是一個監(jiān)視系統(tǒng)運行狀態(tài)和網(wǎng)絡信息的監(jiān)視系統(tǒng)。Nagios能監(jiān)視所指定的本地或遠程主機以及服務,提供異常通知功能,同時還可以安裝各種模塊插件,自定義監(jiān)控腳本等。
兩者區(qū)別:Cacti偏重于網(wǎng)絡流量,系統(tǒng)負載方面的監(jiān)控。而 Nagios偏重于系統(tǒng)服務方面的監(jiān)控,你可以在被監(jiān)控的機器上寫自己的程序(shell,c 或 perl都可以) 。Nagios則通過這些腳本來對服務進行監(jiān)控。Nagios可以和短信發(fā)送機配合用來監(jiān)控規(guī)模較大的網(wǎng)站。

General Options: ------------------------- Nagios executable: nagios Nagios user/group: nagios,nagios Command user/group: nagios,nagcmd Event Broker: yes Install ${prefix}: /usr/local/nagios Install ${includedir}: /usr/local/nagios/include/nagios Lock file: ${prefix}/var/nagios.lock Check result directory: ${prefix}/var/spool/checkresults Init directory: /etc/rc.d/init.d Apache conf.d directory: /etc/httpd/conf.d Mail program: /bin/mail Host OS: linux-gnu IOBroker Method: epoll Web Interface Options: ------------------------ HTML URL: http://localhost/nagios/ CGI URL: http://localhost/nagios/cgi-bin/ Traceroute (used by WAP):
Review the options above for accuracy. If they look okay,
type 'make all' to compile the main program and CGIs.
安裝
[root@www nagios-4.1.1]# make all
*** Compile finished ***
If the main program and CGIs compiled without any errors, you
can continue with installing Nagios as follows (type 'make'
without any arguments for a list of all possible options):
make install
- This installs the main program, CGIs, and HTML files
make install-init
- This installs the init script in /etc/rc.d/init.d
make install-commandmode
- This installs and configures permissions on the
directory for holding the external command file
make install-config
- This installs *SAMPLE* config files in /etc/nagios
You'll have to modify these sample files before you can
use Nagios. Read the HTML documentation for more info
on doing this. Pay particular attention to the docs on
object configuration files, as they determine what/how
things get monitored!
make install-webconf
- This installs the Apache config file for the Nagios
web interface
make install-exfoliation
- This installs the Exfoliation theme for the Nagios
web interface
make install-classicui
- This installs the classic theme for the Nagios
web interface

網(wǎng)頁登錄
Nagios4.1.1版本主頁中間顯示不了www.youtube.com頁面,可是為了追求美觀,干脆把它替換掉,找到URL的位置把它替換為全球實時展示******網(wǎng)站,觀賞全球******走向O(∩_∩)O哈哈~
[root@www share]# grep 'www.youtube.com' main.php
[root@www share]# vim /usr/local/nagios/share/main.php ('<iframe width="100%" height="100%" src="http:// www.youtube.com/embed/videoseries?l ist=PLN-ryIrpC_mCUW1DFwZpxpAk00i60lSkE&iv_load_policy=3&rel=0 " frameborder="0" allowfullscreen></iframe>') 替換url: ('<iframe width="100%" height="100%" src="http:// map.norsecorp.com " frameborder="0" allowfullscreen></iframe>')
