Abstract

A method for integrating responses to asynchronous events is provided. A hypervisor of a host receives a request from a network manager to re-direct asynchronous events from a guest to an address of an event aggregation manager distinct from an address of the network manager. The hypervisor receives an asynchronous event having a destination address of the network manager from the guest. The hypervisor maps the destination address of the network manager to the address of the event aggregation manager. The hypervisor transmits the asynchronous event to the event aggregation manager.

Claims

1. A computer-implemented method for integrating responses to asynchronous events, the method comprising:

receiving a request, at a hypervisor of a host from a network manager, to re-direct asynchronous events from a guest to an address of an event aggregation manager distinct from an address of the network manager;

receiving, at a hypervisor, an asynchronous event having a destination address of the network manager from the guest;

mapping, by the hypervisor, the destination address of the network manager to the address of the event aggregation manager; and

transmitting, from the hypervisor, the asynchronous event to the event aggregation manager.

2. The method of claim 1, wherein the mapping comprises configuring, by the hypervisor, the guest to re-direct asynchronous events from a guest to the address of the event aggregation manager.

3. The method of claim 2, further comprising storing, by the hypervisor, the address of the event aggregation manager in the registry of the guest during booting of the guest.

4. The method of claim 1, wherein the asynchronous event is an SNMP trap or a WMI trap.

5. The method of claim 4, wherein the SNMP trap is received from a virtual agent of the guest.

6. The method of claim 1, wherein the address of the event aggregation manager corresponds to an ID, a URL, an IP address, or a MAC address.

7. A computer-implemented method for integrating responses to asynchronous events, comprising:

transmitting a command, from a network manager to a hypervisor of a host, to cause the hypervisor to re-direct asynchronous events generated by a guest residing on the host to an address of an event aggregation manager distinct from an address of the network manager, wherein the asynchronous events generated by the guest have a destination address of the network manager, and wherein the hypervisor is configured to map the destination address of the network manager to the address of the event aggregation manager;

receiving, at the network manager from the event aggregation manager, an asynchronous event from the guest; and

invoking, by the network manager, an event handler based on a characteristic of the asynchronous event.

8. The method of claim 7, wherein the asynchronous event is an SNMP trap or a WMI trap.

9. The method of claim 7, wherein the address of the event aggregation manager corresponds to an ID, a URL, an IP address, or a MAC address.

10. The method of claim 7, wherein the event handler is invoked on a per-event basis.

11. The method of claim 7, wherein the event handler is invoked on a per-combination-of-events basis.

12. The method of claim 7, further comprising gathering information about the guest based on data associated with the received asynchronous event.

13. The method of claim 7, wherein the network manager registers with the event aggregation manager to receive asynchronous events having the characteristic.

14. The method of claim 7, wherein the network manager polls the event aggregation manager for asynchronous events on a periodic basis.

15. The method of claim 7, wherein the received asynchronous event is configured to be masked at the event aggregation manager.

16. The method of claim 7, wherein the event aggregation manager is configured to receive a registration request from the network manager to receive an asynchronous event having at least one characteristic.

17. The method of claim 7, wherein the event aggregation manager is implemented in a server associated with the network manager.

18. The method of claim 7, wherein the event aggregation manager is implemented in a server distinct from a server associated with the network manager.

19. A computer system, comprising:

a memory;

a processing device, coupled to the memory; and

a hypervisor hosted by the computer system, having access to the memory and use of the processor, the hypervisor configured to;

receive a request to re-direct asynchronous events from a guest to an address of an event aggregation manager distinct from an address of the network manager;

receive an asynchronous event having a destination address of the network manager from the guest;

map the destination address of the network manager to the address of the event aggregation manager; and

transmit the asynchronous event to the event aggregation manager.

20. A non-transitory computer-readable storage medium including instructions that, when accessed by a processing system, cause the processing system to perform a method for integrating responses to asynchronous events, the method comprising:

receiving a request to re-direct asynchronous events from a guest to an address of an event aggregation manager distinct from an address of the network manager;

receiving an asynchronous event having a destination address of the network manager from the guest;

mapping the destination address of the network manager to the address of the event aggregation manager; and

transmitting the asynchronous event to the event aggregation manager.
