之前在excel里面分析log数据,简直日了*了。 现在用python在处理日志数据.
主要涉及 matplotlib,open和循环的使用。
日志内容大致如下
2016-10-21 21:07:59,787 [7 MainWindowForm]INFO: update time 136.6314 2016-10-21 21:07:59,908 [7 KinectServer]INFO: lClientSockets[0] elapsed time 16. 2016-10-21 21:07:59,918 [7 KinectServer]INFO: lClientSockets[1] elapsed time 107. 2016-10-21 21:07:59,929 [7 MainWindowForm]INFO: update time 135.1311 2016-10-21 21:08:00,039 [7 KinectServer]INFO: lClientSockets[0] elapsed time 14. 2016-10-21 21:08:00,045 [7 KinectServer]INFO: lClientSockets[1] elapsed time 103. 2016-10-21 21:08:00,053 [7 MainWindowForm]INFO: update time 118.1132
python处理代码
import matplotlib.pyplot as plt input = open('serverlog.txt', 'r') rangeUpdateTime = [0.0] for line in input: line = line.split() if 'update' in line: rangeUpdateTime.append(float(line[-1])) plt.figure('frame time') plt.subplot(211) plt.plot(rangeUpdateTime, '.r',) plt.grid(True) plt.subplot(212) plt.plot(rangeUpdateTime) plt.grid(True) plt.show()
结果
真心是又好又快出结果^_^
