= Extended plugin from Jan Tomasek =
* Jan has posted another plugin on http://forum.openvz.org/index.php?t=msg&goto=15122, where I've fixed two things:*# "exit 0" in the "config" block*# Replaced "vals=($str); echo ${vals[0]}" with "echo ${str%% *}" (the former was causing problems I don't remember anymore)* v1.3.2 (2008/08/09)*# If only 1 variable is graphed, also display maxheld, barrier and limit
<source lang="bash">
#!/bin/sh
# - "exit 0" in "config" block
# - Use "echo ${str%% *}" in "suggest", instead of "vals=($str); echo ${vals[0]}"
#
# Revision 1.3.2 2008/08/09 12:30:00 Christian Rubbert <crubbert@xrc.de>
# * Feature
# - If only 1 variable is graphed, also display maxheld, barrier and limit
