23 Revision 1.24 2007-11-17 09:34:07 arjen
24 Cleaned up some leftovers
26 Revision 1.23 2007/11/03 10:31:12 arjen

28 New issue type: 'property out of range'.
30 Revision 1.22 2007/10/23 11:23:52 arjen
31 Record the date when adding the number of abuses for an IP address
34 Revision 1.21 2007/01/11 13:47:41 arjen
35 Log_adv and derived tables removed.
36 Create notifications from log entries with pattern matching.
38 Revision 1.20 2005/06/04 07:15:16 arjen
39 Added pattern check on log entries with the service_pattern table.
41 Revision 1.19 2004/01/10 20:04:12 arjen
42 Send email about open notifications to an object's users.
44 Revision 1.18 2003/12/03 08:07:21 arjen
45 Changed the type of log_adv_daemon_email.delay and log_adv_daemon_email.xdelay
46 from time to interval. These delays can be more than 24 hours.
48 Revision 1.17 2003/10/29 09:58:29 arjen
49 Create separate notifications for different objects in service_check().
51 Revision 1.16 2003/09/03 12:48:48 arjen
52 Check the log table against the servies running on an object and
53 create notifications if a service is not supposed to be available
54 or is not known at all.
56 Revision 1.15 2003/09/02 12:48:09 arjen
57 BUGFIX: Secondary indices on log_notification were unique.
58 Additional information in the 'usr' table: 'display_name' and 'email'.
59 Added new issues and services.
61 Revision 1.14 2003/09/01 06:51:07 arjen

72 Revision 1.11 2003/07/09 07:25:02 arjen
73 Gcm_daemon gathers statistics on parameters, notifications, etc. for all objects.
75 Revision 1.10 2003/03/29 08:33:58 arjen
76 In phpclasses/db.class.php: Added the database connection string as
77 an argument to the function copy_db_class.
78 Fixed the PHP member function db::db_connect(). The Postgres connection
79 string is now passed as an argument to that function.
81 Revision 1.9 2003/02/21 08:37:59 arjen
82 Added new table to the database: log_adv_daemon_email.
