23 Revision 1.21 2007-01-11 13:47:41 arjen
24 Log_adv and derived tables removed.
25 Create notifications from log entries with pattern matching.
27 Revision 1.20 2005/06/04 07:15:16 arjen
28 Added pattern check on log entries with the service_pattern table.
30 Revision 1.19 2004/01/10 20:04:12 arjen
31 Send email about open notifications to an object's users.
33 Revision 1.18 2003/12/03 08:07:21 arjen
34 Changed the type of log_adv_daemon_email.delay and log_adv_daemon_email.xdelay
35 from time to interval. These delays can be more than 24 hours.
37 Revision 1.17 2003/10/29 09:58:29 arjen
38 Create separate notifications for different objects in service_check().
40 Revision 1.16 2003/09/03 12:48:48 arjen
41 Check the log table against the servies running on an object and
42 create notifications if a service is not supposed to be available
43 or is not known at all.
45 Revision 1.15 2003/09/02 12:48:09 arjen
46 BUGFIX: Secondary indices on log_notification were unique.
47 Additional information in the 'usr' table: 'display_name' and 'email'.
48 Added new issues and services.
50 Revision 1.14 2003/09/01 06:51:07 arjen
51 Accept command argument '-c config' to use an alternate
52 gnucomo configuration.
54 Revision 1.13 2003/08/14 10:22:42 arjen
57 Revision 1.12 2003/08/05 07:46:37 arjen
58 BUGFIX: Print an error message if a parameter does not have
61 Revision 1.11 2003/07/09 07:25:02 arjen
62 Gcm_daemon gathers statistics on parameters, notifications, etc. for all objects.
64 Revision 1.10 2003/03/29 08:33:58 arjen
65 In phpclasses/db.class.php: Added the database connection string as
66 an argument to the function copy_db_class.
67 Fixed the PHP member function db::db_connect(). The Postgres connection
68 string is now passed as an argument to that function.
70 Revision 1.9 2003/02/21 08:37:59 arjen
71 Added new table to the database: log_adv_daemon_email.
