Revision: 1.34
Committed: Mon Feb 26 23:58:42 2001 UTC (23 years, 9 months ago) by tdb
Content type: text/plain
Branch: MAIN
Changes since 1.33: +5 -5 lines
Log Message:
Some cases weren't working. This was due to me using .* instead of [^\s]+, whic
I gather is "greedy". It was getting the number of users instead of the minutes.
This should fix those erratic spikes we've seen.

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
