# tSmoke.pl
# Dan McGinn-Combs, Sep 2003
# tSmoke.v 0.4 2004/03 McGinn-Combs
#-----------------------------------------------
#
# Modified for Smokeping official distribution since 20050526
# Original README follows
#
# tSmoke.v04.README
# - added downtime report (--downtime)
# - a few tweaks to the calculations to ensure it's consistent
# 
# tSmoke.v03.README
# - Initial Release
# - The script, started through cron, will cull through a config file and 
# determine which hosts are down at a point in time (Morning report) and 
# send out an smtp message to a mobile phone (for example).
# 
# - It will also cull through the same config file and, using an included html
# file (small change to General section of the config file), send an html 
# message which shows the availability over the past day, week, month 
# and quarter.
# 
# - It can also show detail data depending on the setting of 
# command line option "detail".
# 
# tSmoke.v02.README
# - Local testing version
#-----------------------------------------------
#
# 1) This program is run via CRON or the command line
# 2) It extracts RRD information from a smokeping config file
# 3) It pulls data from RRD files to determine if anything is offline, that is returning 0 PINGs
# 4) tSmoke reports status via an SMTP alert
# 5) tSmoke also generates an SMTP mail showing historical view of availability
#

# Jim Horwath of Agere Systems Inc. for his examples and pointers to Spreadsheet::WriteExcel
# Frank Harper the author of SLAMon, a tool for tracking Service Level Agreements
# Tobias Oetiker, or course, the author of Smokeping, RRDTool and MRTG
