acme网站上几个http小工具

1. http_load: http://www.acme.com/software/http_load/

同apache ab和JMeter一样可以对数据库和web服务器作压力测试。
$> vi urls

$> ./http_load -rate 5 -seconds 10 urls
49 fetches
2 max parallel
289884 bytes
in 10.0148 seconds 5916 mean bytes/connection 4.89274 fetches/sec

24.488 min msecs/first-response: 63.5362 mean
81.624 max
57.803 min
HTTP response codes: code 200 -- 49

2. http_ping: http://www.acme.com/software/http_ping/

与ping命令类似，但是是通过http请求来检查服务器，而非ICMP请求服务器返回响应。

$> http_ping http://www.example.com/
