What I gonna do is to read a bunch of data from a file, and perform some data processing from the string.
- split() is the Perl function which I will use for filtering the data.
- open for reading a file into array.
I took MRTG’s data log to do some data processing. On the first column of MRTG log file is Unix timestamp, I would like to print the unix Timestamp to human readable date and time, the other columns are traffic in and out in bytes, which I want to find out which traffic is more than certain values.
