-- Function Description:
    This tool is mainly used to perform the performance test function of the object storage system. It can automatically generate the defined test data size for object upload and download, which is excellent in performance and execution efficiency.
    Customize the number of concurrently configured and uploaded objects, customize the test business interface, and currently support most object interface operations.
    The tool is adapted to the Huawei cloud object storage service interface. If other object interfaces are connected, the appropriate interface header field modification can be adapted.
    Is the best tool for performance testing verification in the industry.

2. Support long and short connections.
     3. Support domain name and IP two ways to request.
     4. Support HTTP/HTTPs configuration in two ways.
     5. Support MD5 value when uploading and downloading objects.
     6. Support random object name and random object size when uploading objects.
     7. Performance result statistics function: including real-time statistical results: including online concurrent numbers, error rate, TPS, throughput, and performance data in a real-time period.
-- Installation & Configuration /INSTALL&CONFIG:
     1. Requires Python environment 2.6.x or 2.7.x. To test the HTTPS encryption algorithm of TSL1.1 and above, you need >=2.7.9
     2. If you want to use the DNS domain name request method, you need to:
      a) The domain name cache service is not running on the execution machine of the program. Otherwise, the request is sent to the same OSC. The query closes the nscd method: service nscd status|stop
      b) The configured domain name can be parsed normally. Configure the dns server in /etc/resolv.conf.
      
      
-- Run /HOW TO RUN:

     1. Create a test account:
        To configure AK SK authentication, you need to construct a test account in the users.dat file in the following format for the tool to read. (1 or more, configured as needed)
      accountName,accessKey,secretKey,
      accountName1,accessKey1,secretKey1,
      accountName2,accessKey2,secretKey2,
      ...
	2. Edit config.dat to configure the test model
	
	3. Run, you can specify parameters, the specified parameters override the parameters in the configuration file
     ./run.py [test case number] [number of users] [specify loaded configuration file]
    
	4. View the results, directory ./result/:
	  example:
	  2013.12.05_06.14.50_HeadBucket_200_brief.txt indicates the final test result of the 200 user concurrent HeadBucket operation.
      2013.12.05_06.14.50_HeadBucket_200_detail.csv indicates the detailed result of all requests of 200 users concurrent HeadBucket operation.
      Archive.csv The result of the archive after each execution.
        ProcessId,UserName,RequestSq,Operation,Start_At,End_At,Latency(s),DataSend(Bytes),DataRecv(Bytes),Mark,RequestID,Response

    2014.03.05_06.18.13_MixOperation_2_realtime.txt indicates the performance statistics of the sampling period of 2 users concurrently with the MixOperation operation and real-time interval of 5 seconds (configurable parameter StatisticsInterval).

Other instructions:
     1. There are successive dependencies between requests. If you upload an object, you need to run the creation bucket before.
     2. The tool prints the log file log/obsPyTool.log. The log level can be configured in the logging.conf configuration file:
         Optional level: DEBUG (details for all requests), WARNING (>=400 request log), ERROR (>=500 request)
     3. Error code description:
            'connection reset by peer': '9998', # connection class error: server refused to connect

-- 安装&配置/INSTALL&CONFIG:
    1. 要求python环境2.6.x或2.7.x，若要测试TSL1.1以及以上版本的HTTPS加密算法，需要>=2.7.9 
    2. 如果要使用DNS域名请求方式，需要：
     a) 本程序的执行机上没有运行域名缓存服务，否则造成请求均发送到同一个OSC,查询关闭nscd的方法：service nscd status|stop
     b) 配置的域名可以正常解析。在/etc/resolv.conf内配置dns服务器。

-- 运行/HOW TO RUN:

    1. 创建测试帐户：
       配置使用AK SK鉴权，则需要在users.dat文件中按如下格式构造测试帐户供工具读取。（1个或多个，根据需要配置）
      accountName,accessKey,secretKey,
      accountName1,accessKey1,secretKey1,
      accountName2,accessKey2,secretKey2,
      ...

    2. 编辑 config.dat，配置测试模型

    3. 运行，可指定参数，指定的参数覆盖配置文件中的参数
    ./run.py  [测试用例编号] [用户数] [指定加载的配置文件]

    4. 查看结果，目录./result/：
     2013.12.05_06.14.50_HeadBucket_200_brief.txt 表示200用户并发HeadBucket操作最终测试结果。

其它说明：
    1. 请求间有先后依赖关系。如上传对象需要之前运行过创建桶。
    2. 工具打印日志文件log/obsPyTool.log,日志级别在logging.conf配置文件内可配置：
        可选级别：DEBUG（所有请求的详细信息)、WARNING（>=400请求日志)、ERROR(>=500请求) 
    3. 错误码描述：
