Information acquisition method and device

The embodiment of the invention provides an information acquisition method and a device thereof, and relates to the field of electronic information technology. According to the invention, the problem that bandwidth distribution and utilization conditions of each electric terminal in a CDN network cannot be acquired is solved; users can actually adjust network planning of a CDN server according to actual bandwidth distribution and utilization conditions; and it is convenient for later maintenance of bandwidth. Meanwhile, work efficiency of the server can be raised. The method specifically contains the following steps: the server acquires log files of the electric terminals; bandwidth data of the electric terminals in the log files are acquired; according to the bandwidth data of the electric terminals, different log files corresponding to the bandwidth data and log data in the log files are acquired so as to obtain a log data set; and the obtained log data in the log data set is analyzed, and bandwidth distribution and utilization conditions of the electric terminals are determined. The method provided by the invention is applied in acquisition of bandwidth distribution and utilization conditions.
