0.名稱(chēng)apache mod_watch: Monitoring Interface for Apache 1.3 & MRTG樣本:font 1.描述mod_watch 這個(gè)apache module可以用來(lái)觀察並收集每一個(gè)虛擬主機(jī)存取的狀況這個(gè)module被用來(lái)和MRTG結(jié)合,以圖形方式展示資料的進(jìn)出. 2.安裝路徑: /usr/ports/www/mod_watch/ 3.設(shè)定修改 /usr/local/etc/apache/httpd.confA./watch-info 會(huì)顯示一些數(shù)值,分別是:名稱(chēng)已啟動(dòng)時(shí)間(秒) 流入封包流出封包request數(shù)讀取頁(yè)面ohaha.ks.edu.tw 6825812752807447192352631ifNameifUptimeifInOctets ifOutOctets ifRequests ifDocuments新增 /watch-info 設(shè)定# 針對(duì)主網(wǎng)頁(yè)SetHandler watch-info# 針對(duì)個(gè)人網(wǎng)頁(yè)SetHandler watch-info B./watch-copyright 顯示版本及版權(quán)訊息新增 /watch-copyright 設(shè)定SetHandler watch-copyrightOrder allow,denyAllow from 163.19.163.97 # 只允許我自己看..其實(shí)有跟沒(méi)有一樣到處都看到版本號(hào)..~"~說(shuō)明:預(yù)設(shè)狀況只給某些授權(quán)的人觀看. 修改上述的ip位址改成自己信任的區(qū)段即可.
