HTTP/HLS/RTMP超级负载测试工具

这个负载测试工具是网游分享的工具，可以在http://blog.csdn.net/win_lin/article/details/11835011 或者https://github.com/winlinvip/st-load 找到非常详细的介绍，包括如何安装，如何使用。

服务器负载测试工具(st-load)：

1. 模拟huge并发：2G内存就可以开300k连接。基于states-threads的协程。
2. 支持HLS解析和测试，下载ts片后等待一个切片长度，模拟客户端。支持HLS点播和直播。
3. 支持HTTP负载测试，所有并发重复下载一个http文件。可将80Gbps带宽测试的72Gbps。
4. 支持RTMP流测试，一个进程支持5k并发。使用nginx-rtmp的协议直接将chunk流解析为messgae。

流媒体相关补充

rtmp://10.169.0.66/rtmp/live 这样的格式，我们称之为一个rtmp流。通用格式为 rtmp://ip_addr/application_name/stream_name(id)

使用方法

将工具下载下来：git clone https://github.com/winlinvip/st-load.git

编译：

• 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负载：./objs/sb_http_load

hls负载: ./objs/sb_hls_load

rtmp收看负载: ./objs/sb_rtmp_load

rtmp创建直播流负载: ./objs/sb_rtmp_publish

如果不知道需要跟什么参数可以使用 ./objs/sb_http_load -help 查看

收看直播与创建直播只需要关注：nread与nwrite即可。其他内容有待进一步调查
