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:

receiving, at a computing system, a first system event from a monitored system to create a first event item;

receiving, at the computing system, a second system event from the monitored system;

modifying, by the computing system, the first event item based upon the second system event to create a modified event item;

collecting, by the computing system, in database of event items, a batch of event items including the modified event item and not the first event item;

periodically notifying, by the computing system, a client of the batch of event items; and

directly notifying, by the computing system, the client of the modified event item independently of the periodic batch notification if the modified event item satisfies a priority condition, respectively.

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 first event item and the modified event item.

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 new event items and event modification items from the two or more collecting database servers; and

further comprising directly notifying a second client of a new priority event item or a modified priority event item 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 new event item and the event modification item from aggregation database server;

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

6. A network management system comprising:

a plurality of processors;

a probe, executed on the plurality of processors, for receiving a first system event and a second system event from a monitored system and creating a modified event item based upon a modification of the first system event based upon the second system event;

a collection database server, executed on the plurality of processors, collecting, in a database of event items, a batch of event items including the modified event item;

a replicator, executed on the plurality of processors, for periodically notifying a client of the batch of event items; and

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

7. A network management system according to claim 6 wherein the client comprises an aggregation database server replicating new event items and 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 new event items and event modification items from the two or more collecting database servers; and

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

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 new event items and 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 a modified event item independently of the periodic batch notification if the new or modified event item satisfies a priority condition, respectively.

11. A computer program product comprising non-transitory 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 on the computing system performs:

intercepting a first system event and a second system event from a monitored system;

creating a modified system event item based upon the first and second system events;

collecting, in database of event items, a batch of event items including the modified system event item;

periodically notifying a client of the batch of event items; and

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

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 new event items and 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 new event items and event modification items from the two or more collecting database servers; and

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

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 new event items and event modification items from the aggregation database server;

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