Abstract

This invention relates to a method, system and computer program product for a network management system comprising:

a probe for intercepting a system event from a monitored system and creating event items or modifying event items associated with the system events; a collection database server collecting, in database of event items, a batch of new event items or modifications to an existing event items; a client; a replication means for periodically notifying a client of the batch of new event items or event item modification; and an acceleration mechanism for directly notifying the client of a new event item or modified event item independently of the periodic batch notification if the new or modified event item satisfies a priority condition.

Claims

1. A method of managing a network comprising:

intercepting a system event from a monitored system and creating event items or modifying event items associated with the system events;

collecting, in database of event items, a batch of new event items or modifications to an existing event items;

periodically notifying a client of the batch of new event items or event item modification; and

directly notifying the client of a new event item or modified event item independently of the periodic batch notification if the new or modified event item satisfies a priority condition.

2. A method according to claim 1 wherein the collecting step is performed in a first database server;

the client comprises a second database server replicating the new event items and/or event item modifications.

3. A method according to claim 2 wherein the client further comprises a gateway that receives the notifications;

pulls event item data from the first database server and then pushes the event item data to the second database server.

4. A method according to claim 1 wherein the collecting step is performed in a collecting layer of two or more database servers, each having at least one or more probes intercepting events;

the client is an aggregation layer comprising an aggregation database server that replicates in a central location all the new event items and/or event modification items from the two or more collecting database servers; and

further comprising directly notifying a second client of the aggregated new priority event items or modified priority event items independently of the periodic batch notification if the new or modified event item satisfies a priority condition.

5. A method according to claim 4 wherein the second client is a display layer of two or more database servers where each display layer object server replicates a subset of the aggregated new event items and/or event modification items from aggregation database server;

and each display layer database server capable of directly notifying at least one display client of a new event item or modified event items independently of the periodic batch notification if the new or modified event item satisfies a priority condition.

6. A network management system comprising:

a probe for intercepting a system event from a monitored system and creating event items or modifying event items associated with the system events;

a collection database server collecting, in database of event items, a batch of new event items or modifications to an existing event items;

a client;

a replication means for periodically notifying a client of the batch of new event items or event item modification; and

an acceleration mechanism for directly notifying the client of a new event item or modified event item independently of the periodic batch notification if the new or modified event item satisfies a priority condition.

7. A network management system according to claim 6 wherein the client comprises an aggregation database server replicating the new event items and/or event item modifications.

8. A network management system according to claim 7 wherein the client further comprises a gateway that receives the notifications;

pulls event item data from the collection database server and then pushes the event item data to the aggregation database server.

9. A network management system according to claim 6 further comprising a collecting layer of two or more collection database servers, each having one or more associated probes;

the client is an aggregation layer comprising an aggregation database server that replicates in a central location all the new event items and/or event modification items from the two or more collecting database servers; and

further comprising directly notifying a second client of the aggregated new priority event items or modified priority event items independently of the periodic batch notification if the new or modified event item satisfies a priority condition.

10. A network management system according to claim 9 wherein the second client is a display layer of two or more database servers where each display layer object server replicates a subset of the aggregated new event items and/or event modification items from aggregation database server;

and each display layer database server capable of directly notifying at least one display client of a new event item or modified event items independently of the periodic batch notification if the new or modified event item satisfies a priority condition.

11. A computer program product comprising computer readable recording medium having computer readable code stored thereon for a network management system, said computer readable code which when loaded onto a computer system and executed performs the following steps:

intercepting a system event from a monitored system and creating event items or modifying event items associated with the system events;

collecting, in database of event items, a batch of new event items or modifications to an existing event items;

periodically notifying a client of the batch of new event items or event item modification; and

directly notifying the client of a new event item or modified event item independently of the periodic batch notification if the new or modified event item satisfies a priority condition.

12. A computer program product according to claim 11 wherein the collecting step is performed in a first database server;

the client comprises a second database server replicating the new event items and/or event item modifications.

13. A computer program product according to claim 12 wherein the client further comprises a gateway that receives the notifications;

pulls event item data from the first database server and then pushes the event item data to the second database server.

14. A computer program product according to claim 11 wherein the collecting step is performed in a collecting layer of two or more database servers, each having at least one or more probes intercepting events;

the client is an aggregation layer comprising an aggregation database server that replicates in a central location all the new event items and/or event modification items from the two or more collecting database servers; and

further comprising directly notifying a second client of the aggregated new priority event items or modified priority event items independently of the periodic batch notification if the new or modified event item satisfies a priority condition.

15. A computer program product according to claim 14 wherein the second client is a display layer of two or more database servers where each display layer object server replicates a subset of the aggregated new event items and/or event modification items from aggregation database server;

and each display layer database server capable of directly notifying at least one display client of a new event item or modified event items independently of the periodic batch notification if the new or modified event item satisfies a priority condition.
