22 $Log: gcm_daemon.php,v $
23 Revision 1.26 2011-03-24 09:46:36 arjen
24 Resolve a hostname before adding to the abuses.
26 Revision 1.25 2007/12/12 09:06:21 arjen
27 Added a new script gcm_maintenance.php to cleanup the database
28 and check referential integrity. Purging old log entries is
29 removed from the gcm_daemon script.
31 Revision 1.24 2007/11/17 09:34:07 arjen
32 Cleaned up some leftovers
34 Revision 1.23 2007/11/03 10:31:12 arjen
35 Added the class definition for a filesystem parameter.
36 New issue type: 'property out of range'.
38 Revision 1.22 2007/10/23 11:23:52 arjen
39 Record the date when adding the number of abuses for an IP address
42 Revision 1.21 2007/01/11 13:47:41 arjen
43 Log_adv and derived tables removed.
44 Create notifications from log entries with pattern matching.
46 Revision 1.20 2005/06/04 07:15:16 arjen
47 Added pattern check on log entries with the service_pattern table.
49 Revision 1.19 2004/01/10 20:04:12 arjen
50 Send email about open notifications to an object's users.
52 Revision 1.18 2003/12/03 08:07:21 arjen
53 Changed the type of log_adv_daemon_email.delay and log_adv_daemon_email.xdelay
54 from time to interval. These delays can be more than 24 hours.
56 Revision 1.17 2003/10/29 09:58:29 arjen
57 Create separate notifications for different objects in service_check().
59 Revision 1.16 2003/09/03 12:48:48 arjen
60 Check the log table against the servies running on an object and
61 create notifications if a service is not supposed to be available
62 or is not known at all.
64 Revision 1.15 2003/09/02 12:48:09 arjen
65 BUGFIX: Secondary indices on log_notification were unique.
66 Additional information in the 'usr' table: 'display_name' and 'email'.
67 Added new issues and services.
69 Revision 1.14 2003/09/01 06:51:07 arjen
70 Accept command argument '-c config' to use an alternate
71 gnucomo configuration.
73 Revision 1.13 2003/08/14 10:22:42 arjen
76 Revision 1.12 2003/08/05 07:46:37 arjen
77 BUGFIX: Print an error message if a parameter does not have
80 Revision 1.11 2003/07/09 07:25:02 arjen
81 Gcm_daemon gathers statistics on parameters, notifications, etc. for all objects.
83 Revision 1.10 2003/03/29 08:33:58 arjen
84 In phpclasses/db.class.php: Added the database connection string as
85 an argument to the function copy_db_class.
86 Fixed the PHP member function db::db_connect(). The Postgres connection
87 string is now passed as an argument to that function.
89 Revision 1.9 2003/02/21 08:37:59 arjen
90 Added new table to the database: log_adv_daemon_email.
