- About: This program reads in a jitter log file as created
- by the JitterTest.c program and extracts all the jitters
- in the file that are greater than a threshold specified
- as a parameter on the cmd line. It also extracts the
- amount of disk space at (form the "df" out that should also
- be present in the log file) after the jitter extracted.
-
- It writes the data to the stderr (where you may redirect it).
- It is suitable for plotting, as the data is written as
- COL1=UsedSpace COL2=Jitter

- Revision 1.6 2005/11/07 11:15:21 gleixner
- [MTD / JFFS2] Clean up trailing white spaces
-
- Revision 1.5 2001/08/10 19:23:11 vipin
- Ready to be released under GPL! Added proper headers etc.
-
- Revision 1.4 2001/07/02 22:25:40 vipin
- Fixed couple of minor cosmetic typos.
-
- Revision 1.3 2001/07/02 14:46:46 vipin
- Added a debug option where it o/p's line numbers to debug funky values.
-
- Revision 1.2 2001/06/26 19:48:57 vipin
- Now prints out jitter values found at end of log file, after which
- no new "df" disk usage values were encountered. The last "df" disk usage
- encountered is printed for these orphaned values.
-
- Revision 1.1 2001/06/25 19:13:55 vipin
- Added new file- plotJittervsFill.c- that mines the data log file
- outputed from the fillFlash.sh script file and JitterTest.c file
- and produces output suitable to be plotted.
- This output plot may be examined to see visually the relationship
- of the Jitter vs disk usage of the fs under test.
