Revision: 1.37
Committed: Sun Mar 11 12:51:52 2001 UTC (23 years, 8 months ago) by pjm2
Content type: text/plain
Branch: MAIN
Changes since 1.36: +6 -2 lines
Log Message:
Fix for the solaris(?) problem where memory values drop below 10mb.  If
there is a "K" after the number, then we now divide the value by 1024.

9     # by examining the output of some common Unix/Linux commands.
10     # This is a stopgap to act as a generic way of collecting the
11     # data. It is perhaps more reliable than the current Java host
12     # at doing this and it can obviously be used by a C++ program as
13     # well until the C++ host is ready to find the information out
