-# 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
-#
-# Many thanks to the following people for their help and guidance:
-# 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

-=head1 NAME
-
-tSmoke - Commandline tool for sending SmokePing information
-
-=head1 SYNOPSIS
-
-B<tSmoke> [ B<--testmail> | B<--morning> | B<--weekly> | B<--version> | B<--help> | B<--man>]
-
- Options:
-
- --man Show the manpage
- --help Help :-)
- --version Show SmokePing Version
- --testmail Send a test message
- --listrrds List the RRDs used by this Smokeping
- --morning Send a morning synopsis
- --weekly Send a weekly status report
- --to E-mail address to send message (i.e. '--to=xyz@company.com.invalid'
- --detail How much detail to send in weekly report (i.e. '--detail=1')
- --quiet Do not print welcome
-
-=head1 DESCRIPTION
-
-The B<tSmoke> tool is a commandline tool which interfaces with the SmokePing system.
-Its main function is to send a message indicating the current status of the systems
-being monitored by Smokeping or an HTML mail file containing the status over the past day,
-past week and past month including an overview.
-
-Typical crontab used to invoke this are
-
- # Quick morning alert to see what's down
- 0 6 * * * /usr/local/smokeping/bin/tSmoke.pl --q --to=mobilephone@att.net.invalid --morning
- # Weekly report on the percent availability of network systems with no detail
- 0 8 * * * /usr/local/smokeping/bin/tSmoke.pl --q --to=mailbox@company.com.invalid --weekly --detail=0
-
-=head1 SETUP
-
-When installing tSmoke, some variables must be adjusted to fit your local system.
-
-We need to use the following B<libraries>:
-
-=over
-
-=item Smokeping
-
-=item RRDTool Perl bindings
-
-=item Getopt::Long
-
-=back
-
-Set up your libraries:
-
- use lib "/usr/local/smokeping/lib";
- use lib "/usr/local/rrdtool-1.0.39/lib/perl";
-
-Point to your Smokeping B<config> file
-
- my $cfgfile = "/usr/local/smokeping/etc/config";
-
-Modify the Smokeping config file to include a path for tmail in the
-General section:
-
- tmail = /usr/local/smokeping/etc/tmail
