Unfortunately, the only way to format the chart logs in that fashion
is to read the chart data files directly. The chart data logs are
stored in flat files using very simple rules. On a unix system, you
can use the hexdump utility to display the chart data in tab-
delimited form:
hexdump -v -e '"%d" "\t" "%d" "\n"' "InterMapper Settings/Chart
Data/gb733ffa9/L1-Util
Here are the rules:
1. Each data point is stored using 4 bytes for the timestamp and 4
bytes for the value.
2. The timestamps are stored in seconds since 1970 UTC*
3. Percent values are stored in hundreths (e.g. 10,000 == 100.00%)
4. The value -2147483648 is used to mark a discontinuous point, e.g.
when InterMapper starts up.
5. All values are stored in native byte order; big-endian for PowerPC
or Sparc, little-endian for i386.
* Exception for chart files created on Mac OS 9 and earlier --
"negative" timestamps are relative to 1904 using local time zone.

I would like to know if we can change the format of the chats log
to an XML format
I mean: to use logs for stats and other stuff... it will be more
easier to use a comprehensive format like:
<?xml version="1.0" ?>
