Revision: 1.33
Committed: Tue Feb 13 12:18:07 2001 UTC (23 years, 7 months ago) by tdb
Content type: text/plain
Branch: MAIN
Changes since 1.32: +43 -2 lines
Log Message:
Added some basic support for Linux. Linux top chucks out values in K's, so we
need to strip down to Megabytes (to be inline with the others).
Also, not convinced about the output of top, it seems to be stating that only
a couple of % of CPU is in use, when I can see clearly this isn't correct.

8     # A Perl script to return various information about a host machine
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
14     # itself.
