log-files

I have several logs containing lines all starting with a timestamp, so that the following works as expected to merge them: cat myLog1.txt myLog2.txt | sort -n > combined.txt Problem is, that myLog2.txt can also contain lines without a timestamp (e.g. java stack traces). Is there an easy way without any custom scripts to still merge them and preserve the multiline content? Example myLog1.txt 11:48:18.825 [main] INFO org.hibernate.cfg.Environment - HHH000206: hibernate.properties not found 11:48:55.784 [main] INFO o.h.tool.hbm2ddl.SchemaUpdate - HHH000396: Updating schema Example myLog2.txt 11

I am using windows 7 and python 2.7. I want to limit my log file size to 5MB. My app, when it starts, writes to log file, and then the app terminates. When my app starts again, it will write in same log file. So app is not continuously running. App initiates, processes and terminates. My code for logging is: import logging import logging.handlers logging.basicConfig(filename=logfile.log, level="info", format='%(asctime)s %(levelname)s %(funcName)s(%(lineno)d) %(message)s') logging.info("*************************************************") I tried with RotatingFileHandler but it didn't work

After reading an article about the subject from O'Reilly , I wanted to ask Stack Overflow for their thoughts on the matter. Write locally to disk, then batch insert to the database periodically (e.g. at log rollover time). Do that in a separate, low-priority process. More efficient and more robust... (Make sure that your database log table contains a column for "which machine the log event came from" by the way - very handy!) I'd say no, given that a fairly large percentage of server errors involve problems communicating with databases. If the database were on another machine, network
