# by process_sysinfo.pl on the collection computer.

# Version 1.3 20071104

# added capability of e-mailing the results by itself and external configuration file

# Version 1.3.1 20071110

# added du -sk to explicitly do directory sizes in 'k'. Also, fixed some documentation

# Version 1.3.3 20081104

# modified hostname to hostname -f, and allowed user to place custom value in configuration file

# also, modified to go with Debian standards in preparation to creating a debian package.

# Version 2.0 20081208

# Modified to use different libraries for different OS's in preparation to porting to Windows

# Uses different packages based on which OS it is on.

# Version 3.0 20120923

# Major revision. Most internal intelligence pulled out and put into modules and data transfer format has been changed to YAML

#

# Base system only pulls client name, machine name and machine number, all of which can be set in the configuration file

# if the value is not set, it attempts various means to determine the values and, if it fails, aborts with an error message

#    client name -- REQUIRED, must come from configuration file

#    machine name --  REQUIRED, if not set via conf file, attempts hostname command (hostname -f) or module getHostName

#    machine number -- REQUIRED, if not set via conf file, attempts "echo `hostname -f`-clientname | md5sum" or module getSerial

# modules are stored in "configuration directory/modules" (/etc/sysinfo/modules on most Linux systems) and are processed in 

# standard sort order (case sensitive). 

# Module filenames may contain alpha-numeric, underscore and the period only (files containing other characters are ignored).

# Modules should set their exit code to 0 for success, and non-zero for failure

# Modules should return 0 or more tab delimited, newline terminated strings, processed as one record per line

# A module return string line is processed as follows:

#     category \t [category \t ...] \t key \t value

# example:

#    System \t num_cpu \t 1

#    System \t Users \t root \t /root/

# (note, if non-zero exit code returned, return value is assumed to be error message and is printed to STDERR) 

# sysinfo stores the result in a hash, using categories as the keys (case sensitive), thus, the above results in

# $store{'System'}{'num_cpu'} = '1';

# $store{'System'}{'Users'}{'root'} = '/root';

# upon completion, sysinfo converts the $store hash into an XML or YAML string for transfer

# It then sends it to the main server as defined in the conf file.

# NOTE: YAML is hand crafted to kill any requirements for external libraries

# see sub hashToYAML for details

# Version 3.0.1 20160321

# Renamed to sysinfo-client to not conflict with Linux package sysinfo

# created installer in Perl to not rely on package managers

# default path for configuration file changed to /etc/camp/sysinfo-client.conf

# $VERSION changed to $DATA_VERSION to not conflict with $main::VERSION (script version vs data format version)

#

# Version 3.1.0 20160401

# module and script dirs now arrays to be searched. Idea is that default

#    modules/scripts are in installdir/modules or installdir/scripts, and

#    user supplied are in /etc/scripts and /etc/modules

# Tightened up the file systems checks, requiring all scripts and modules

#    be set 0700 at least, and owned by root

# Transport layers now an array, and if one fails to send the report, the others

#    are tried in turn

# Worked on logic for sendReport to give better error checking.

# Doing a search for the configuration file matching cwd, then /etc/camp, then /usr/local/etc/camp

# Self documenting, ie a key for software\tsysinfo-client\version\current version is inserted

#

# Version 3.1.1 20160915 RWR

# set use strict and use warnings, then fixed errors

#

# Version 3.1.2 20160922 RWR

# $exitCode 1 (not applicable to this machine) does not throw warning

#

# Version 3.1.3 20161010 RWR

# Removed extra use warnings

#

# Version 3.1.4 20161023 RWR

# Would error out if moduledir does not exist, added a return

#

# Version 3.1.5 20170327 RWR

# On freeBSD systems, was looking in wrong place for configuration file

#

# Version 3.2.0 20180320 RWR

# Major change in the configuration file format; All entries are loaded into 

# hash %configuration, so clientname is no longer $clientname, but is now

# $configuration{'clientname'}

# NOT backwards compatible

# changed configuration to be loaded into hash (vs directly loaded into variables)

# added UUID to configuration file

#

# Version 3.2.1 20180424 RWR

# Finally got a semi-stable version of this running. Fixed a bunch of bugs

# and appears to be working correctly.

#

# Version 3.3.0 20190419 RWR

# Converted to use YAML config file

#

# Version 3.4.0 20191111 RWR

# adding logging with priority. logging is a hash inside of %cvonfiguration which contains the following

# $configuration{ 'logging' } = {

#    'log type'  => 'string',

#    'log level' => #,

#    'other params' => something,

# };

#

# The default log type is cache, which builds an array of all messages passed. When the log type is changed, the cache is

# checked for values and, if they exist, they are dumped to the log, then removed.

#

# Currently, the only log type is 'file', which has one other additional parameter, 'log path' which

# points to the actual log to be created. The log is NOT limited in size, so use something else to

# do that.

# log level is an integer which is compared the a priority passed to the logging function. The

# higher log level is set, the more verbose the log.

# 0 - Normal, basically logs when the program starts and ends, and any warnings.

# 1 - a little more information about flow

# 2 - Gives ending information on structures

# 3 - Gives a lot of info about structures when they are initialized and at the end

# 4 - Crazy. Dumps just about every structure every time they are changed

#

# $TESTING has been set to a binary. If true, the report is not sent via the transports, but is dumped to /tmp/sysinfo.testing.yaml

#

# Version 3.4.1 20191117 RWR

# Added syslog as a possible option for logging.

#

# Version 3.5.4 20200317 RWR

# changed so report->version will show the version of sysinfo, not the data version

#

# Version 3.5.5 20200317 RWR

# bug fix for bsd/opnsense

# 

# Version 3.6.0 20220607 RWR

# Changed the way upload works. It automatically now passes an additional parameter, upload_type, which with the new upload

# script will choose a directory, allowing one script to handle various uploads

# additionally, if the key 'postRunScript' is in the config, it is assumed to be the name of a script to be run after sysinfo

# completes it's task. This can be used to download/update the program, add new modules, etc..

# find our location and use it for searching for libraries

# sendResults( $parameters, $message, $scriptDirectory )

#

# Sends results of run to server using external script. If external

# script not defined, just print to STDOUT

#

# Parameters

#  $parameters - a hash containing the information necessary to make the transfer

#  $message - the message to be sent

#  $scriptDirectory - path (not filename) of script to be executed

# 

# $parameters contains different key/value pairs depending on the script used

#             for example, a stand-alone SMTP script may need a username/password,

#             smtp server name, port number, from and to address

#             while an http transfer may only need a script name

#             See the individual scripts to determine what parameters need to be

#             filled in.

#             The only required parameter is 'sendScript' which must contain the

#             name of the script to execute (and it must be located in $scriptDirectory)

# SCRIPT must contain one sub named doit, that accepts three parameters, the hash, 

#       the message, and, optionally, the script directory

#

# If script not defined, just dump to STDOUT. With a properly set up cron job, the output

# would then be sent via e-mail to an administrative account, possibly root
