8 ** FILE NAME : gcm_input.cpp
9 ** SYSTEM NAME : Gnucomo - Gnu Computer Monitoring
10 ** VERSION NUMBER : $Revision: 1.13 $
12 ** DESCRIPTION : Application to store client messages into the database
13 ** The client message contains a log file from one of the
14 ** system logs. Gcm_input parses the log file and enters
15 ** the raw data into the 'log' table of the gnucomo database.
17 ** The system log may arrive in one of several forms:
18 ** 1. Log file (archived or not) from a client machine.
19 ** 2. Log file from a client system, arriving in a clear Email.
20 ** 3. Log file from a client machine, arriving in an
23 ** additional information we need that may not be availble in
24 ** the content of the log is:
25 ** - FQDN of the client.
26 ** - Time of arrival of the log
27 ** - Service that created the log.
29 ** If the log arrives in an Email, these items probably are
30 ** available in the mail header. Otherwise, they have to be
31 ** provided as command line arguments.
33 ** Command line arguments:
34 ** -c <name> Configuration name (default = gnucomo).
35 ** -d <date> Date and time of log arrival.
36 ** -h <hostname> FQDN of the client.
37 ** -i Incremental - partial list of parameters.
38 ** -s <service> Service that created the log.
39 ** -T Test mode. Do not alter the database.
40 ** -v Verbose (debug) output.
41 ** -V Print version and exit.

56 $Log: gcm_input.cpp,v $
57 Revision 1.13 2003-12-22 10:20:21 arjen
58 Report if the message type can not be detected.
60 Revision 1.12 2003/12/04 10:38:09 arjen
61 Major redesign. All input is handled through XML. Raw input data is first
62 transformed into an XML document for further processing.
63 A collection of polymorphic classes handle the transformation of various
64 input formats into XML.
65 Classifying input data is done with a finite improbability calculation.
67 Revision 1.11 2003/10/27 13:00:15 arjen
68 Catch exceptions from the database library
70 Revision 1.10 2003/09/03 06:58:31 arjen
71 Changed version string to 0.0.8
73 Revision 1.9 2003/09/01 06:59:26 arjen
74 A date without the time for the '-d <date> option will
75 assume midnight on that date.
77 Revision 1.8 2003/08/16 15:30:19 arjen
78 Fixed a gcc 2 vs. gcc 3 problem
80 Revision 1.7 2003/08/14 10:28:37 arjen
81 Use parameters from a new section 'logging' with three configuration parameters:
82 method - Output method to use for logging.
83 destination - Name of the log output destination.
84 level - Log level: Verbose output if greater than 0.
86 Revision 1.6 2003/08/11 16:56:16 arjen
87 Different kinds of log files are parsed by a collection of objects
88 of different classes, derived from the base class line_cooker
89 Depending on the message content or the message_type element in
90 XML, one of these objects is selected.
92 Logrunner is integrated with gcm_input. Although its functionality
93 is still limited, a connection between logrunner and gcm_input
96 Revision 1.5 2003/08/05 08:11:06 arjen
97 Added two configuration parameters:
98 logfile - Log to this file instead of stderr.
99 verbosity - Verbose output if greater than 0.
100 Added '-i' option for incremental parameter updates
102 Revision 1.4 2003/03/29 08:42:00 arjen
103 Exit without reading any input if the database connection fails.
105 Revision 1.3 2002/11/09 08:04:27 arjen
106 Added a reference to the GPL
108 Revision 1.2 2002/11/04 10:13:36 arjen
109 Use proper namespace for iostream classes
111 Revision 1.1 2002/10/05 10:25:49 arjen
112 Creation of gcm_input and a first approach to a web interface
