btcpool矿池-slparser(share log parser)模块解析

核心机制总结

• 支持三种功能：
  ?? 指定Date和UID，将打印指定日期指定用户的share信息到stdout
  ???? UID=0时，将打印指定日期所有用户的share信息
  ?? 指定Date但未指定UID，读取指定日期sharelog，统计数据并写入数据库
  ???? 按Worker、user、pool三个维度统计:Accept1h、Accept1d、score1h、score1d、Reject1h、Reject1d
  ???? 数据库仅保留最近3个月统计数据
  ?? 如果Date和UID均未指定，将监听文件变化，读取share并统计数据，每15秒写入数据库
  ????* 同时启动Httpd服务，开放ServerStatus和WorkerStatus

slparser命令使用

slparser -c slparser.cfg -l log_dir
slparser -c slparser.cfg -l log_dir2 -d 20160830
slparser -c slparser.cfg -l log_dir3 -d 20160830 -u puid
#-c指定slparser配置文件
#-l指定日志目录
#-d指定日期
#-u指定PUID（即userId），userId为0时dump all, >0时仅输出指定userId的sharelog

slparser.cfg配置文件

slparserhttpd = {
#指定IP和端口
ip = "0.0.0.0";
port = 8081;

#每间隔15s写库
flush_db_interval = 15;
};

#指定sharelog文件路径
sharelog = {
data_dir = "/data/sharelog";
};

#数据库配置，表为table.stats_xxxx
pooldb = {
host = "";
port = 3306;
username = "dbusername";
password = "dbpassword";
dbname = "";
};
