ApacheBench on käsurea tööriis, mis on mõeldud veebiserverite testimiseks. Kasutades ApacheBenchi on võimalik saada ülevaade paigaldatud veebiserveri võimetest. Näidatakse kui palju taotlusi on veebiserver võimeline täitma erinevate koormuste juuras. See annab võimaluse testida veebiserveri käitumist tavakoormusel ning ka eriolukordades, kus pöördumiste arv serveri poole on suurem, kui tavaliselt. | |||
Antud töös on kasutatud ApacheBench versiooni 2.3, ning see on paigaldatud Ubuntu operatsioonisüsteemiga arvutile. ApacheBench tarkvara paigaldamiseks tuleb käsurealt sisestada | |||
sudo apt-get install apache2-utils | |||
Testimiseks kasutatav veebiserver on Apache2, mis on paigaldatud Zentyal operatsioonisüsteemiga arvutile. | |||

Sissejuhatus
ApacheBench on käsurea tööriis, mis on mõeldud veebiserverite testimiseks. Kasutades ApacheBenchi on võimalik saada ülevaade paigaldatud veebiserveri võimetest. Näidatakse kui palju taotlusi on veebiserver võimeline täitma erinevate koormuste juuras. See annab võimaluse testida veebiserveri käitumist tavakoormusel ning ka eriolukordades, kus pöördumiste arv serveri poole on suurem, kui tavaliselt.
Antud töös on kasutatud ApacheBench versiooni 2.3, ning see on paigaldatud Ubuntu operatsioonisüsteemiga arvutile. ApacheBench tarkvara paigaldamiseks tuleb käsurealt sisestada
sudo apt-get install apache2-utils
Testimiseks kasutatav veebiserver on Apache2, mis on paigaldatud Zentyal operatsioonisüsteemiga arvutile.
