+# 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
+#

+=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
