# Revision 1.3 2007/07/19 12:57:00 Jan Tomasek <jan@tomasek.cz> |
7 |
# * rewrited to work with /proc/bc/<VEID>/resources instead of |
8 |
# /proc/user_beancounters, that simplified code and result |
9 |
# is also bit faster. |
10 |
# * added references to OpenVZ wiki |
11 |
# Revision 1.3.1 2008/05/13 01:26:00 Daniel Hahler <http://daniel.hahler.de/> |
12 |
# * Minor fixes |
13 |
# - "exit 0" in "config" block |
14 |
# - Use "echo ${str%% *}" in "suggest", instead of "vals=($str); echo ${vals[0]}" |
15 |
# |
16 |
# Revision 1.3.2 2008/08/09 12:30:00 Christian Rubbert <crubbert@xrc.de> |
17 |
# * Feature |
18 |
# - If only 1 variable is graphed, also display maxheld, barrier and limit |
