# Plugin to monitor various environment sensors provided by envstat(8)
# on NetBSD
#
# Requirements:
# 	- envsys(4) driver configured and supported hardware present
# 	- envstat(8) program present
#
# Parameters supported:
#
# 	config
# 	autoconf
# 	suggest
#
# $Log: sensors_.in,v $
# Revision 1.2  2006/07/21 23:28:37  abs
# Use PKG_SYSCONFSUBDIR so PKG_SYSCONFBASE can be set
# Use REPLACE_PERL on all plugins
# Adjust sensors_ to work with NetBSD 3
# Bump PKGREVISION
#
# Revision 1.1.1.1  2006/06/04 20:53:57  he
# Import the client version of the Munin system monitoring/graphing
# tool -- project homepage is at http://munin.sourceforge.net/
#
# This package has added support for NetBSD, via a number of new plugin
# scripts where specific steps needs to be taken to collect information.
#
# I also modified the ntp_ plugin script to make it possible to not
# plot the NTP poll delay, leaving just jitter and offset, which IMO
# produces a more telling graph.
