HTTP/HLS/RTMP超級負載測試工具(轉)
這個負載測試工具是網遊分享的工具，可以在http://blog.csdn.net/win_lin/article/details/11835011 或者https://github.com/winlinvip/st-load 找到非常詳細的介紹，包括如何安裝，如何使用。
服務器負載測試工具(st-load)：
- 模擬huge並發：2G內存就可以開300k連接。基於states-threads的協程。
- 支持HLS解析和測試，下載ts片後等待一個切片長度，模擬客戶端。支持HLS點播和直播。
- 支持HTTP負載測試，所有並發重復下載一個http文件。可將80Gbps帶寬測試的72Gbps。
- 支持RTMP流測試，一個進程支持5k並發。使用nginx-rtmp的協議直接將chunk流解析為messgae。
流媒體相關補充
rtmp://10.169.0.66/rtmp/live 這樣的格式，我們稱之為一個rtmp流。通用格式為 rtmp://ip_addr/application_name/stream_name(id)
使用方法
將工具下載下來：Git clone https://github.com/winlinvip/st-load.git
編譯：
- cd st-load
- ./configure
- make
使用：./objs/sb_rtmp_load -c 1 -r rtmp://127.0.0.1:1935/live/livestream
更多使用方法
Usage: ./sb_rtmp_publish <Options> <-u URL>
./sb_rtmp_publish base on st(state-threads), support huge concurrency.
Options:
-c CLIENTS, --clients CLIENTS The concurrency client to start to request. defaut: 1
-r URL, --url URL The load test url for each client to download/process.
-t REPEAT, --repeat REPEAT The repeat is the number for each client to download the url.
ie. rtmp://127.0.0.1:1935/live/livestream_{i}
default: 0. 0 means infinity.
-s STARTUP, --start STARTUP The start is the ramdom sleep when thread startup in seconds.
defaut: 5.00. 0 means no delay.
-d DELAY, --delay DELAY The delay is the ramdom sleep when success in seconds.
default: 1.00. 0 means no delay. -1 means to use HLS EXTINF duration(HLS only).
-e ERROR, --error ERROR The error is the sleep when error in seconds.
defaut: 3.00. 0 means no delay.
-m SUMMARY, --summary SUMMARY The summary is the sleep when report in seconds.
etasks is error_tasks, statks is sub_tasks, estatks is error_sub_tasks.
duration is the running time in seconds, tduration is the avarage duation of tasks.
nread/nwrite in Mbps, duration/tduration in seconds.
defaut: 30.00. 0 means no delay.
-v, --version Print the version and exit.
-h, --help Print this help message and exit.
Examples:1. start a client
./sb_rtmp_publish -i doc/source.200kbps.768x320.flv -c 1 -r rtmp://127.0.0.1:1935/live/livestream
2. start 1000 clients
./sb_rtmp_publish -i doc/source.200kbps.768x320.flv -c 1000 -r rtmp://127.0.0.1:1935/live/livestream_{i}
3. start 10000 clients
./sb_rtmp_publish -i doc/source.200kbps.768x320.flv -c 10000 -r rtmp://127.0.0.1:1935/live/livestream_{i}
4. start 100000 clients
./sb_rtmp_publish -i doc/source.200kbps.768x320.flv -c 100000 -r rtmp://127.0.0.1:1935/live/livestream_{i}
http負載：./objs/sb_http_load
hls負載: ./objs/sb_hls_load
rtmp收看負載: ./objs/sb_rtmp_load
rtmp創建直播流負載: ./objs/sb_rtmp_publish
如果不知道需要跟什麽參數可以使用 ./objs/sb_http_load -help 查看

收看直播與創建直播只需要關註：nread與nwrite即可。其他內容有待進一步調查
