Revision: 1.29
Committed: Mon Feb 5 17:51:56 2001 UTC (23 years, 9 months ago) by pjm2
Content type: text/plain
Branch: MAIN
Changes since 1.28: +6 -5 lines
Log Message:
Load information is now obtained from the 'uptime' command rather than
'top' - top is not as quick and rather more inconsistent across platforms.

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.
