视讯多点控制单元运行日志系统的设计

针对视讯MCU(Multi-Point Control Unit)系统庞大,功能复杂,系统运行过程中出错原因多样化的特点,通过改写Linux系统下的syslogd进程,引入一种快速高效的信息定位方法。将改写后的syslogd做为MCU的一个子模块,当MCU系统运行时,将用户操作、各模块间的交互消息、各模块的关键动作、出错信息(出错模块、错误类型、详细原因、具体位置)等通过syslogd进程记录下来,供开发人员定位错误,改进设计,提高软件健壮性。实践证明该方法能有效记录系统运行日志,快速定位错误,提高了软件开发的速度。

Design of Run-log System of Multi-Point Control Unit in Video Communication

Concerning the hugeness of system,the complexity of functions and the variety of causes for faults during operation of MCU(Multi-Point Control Unit),this article proposes a fast and efficient approach for information locating by rewriting the syslogd process in Linux.The rewritten syslogd process,which now servers as a sub module of MCU,will record all information about key operations and error logs(error modules,error type,detailed causes and specific locations) while system runs.The information can be uti...
