8 ** FILE NAME : gcm_input.cpp
9 ** SYSTEM NAME : Gnucomo - Gnu Computer Monitoring
10 ** VERSION NUMBER : $Revision: 1.5 $
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.
