Abstract

An information processing apparatus is provided. The information processing apparatus includes an event detecting unit to detect events, an event notifying information generating unit to generate event notifying information, an event notifying information storage to store the event notifying information in a predetermined arrangement, a client information list storage to store information concerning the client device to which event information concerning each of the events is provided, a notifying unit to provide a piece of the event information corresponding to a first event to the client device, and a judging unit to judge whether the piece of the event information was provided to the client device normally. The notifying unit provides another piece of the event information corresponding to a second event, when the judging unit judges the precedent piece of the event information was provided to the client device normally.

wherein the notifying unit provides another piece of the event information corresponding to a second event among the plurality of events, which occurs subsequently to the first event, according to the event notifying information when the judging unit judges that the precedent piece of the event information was provided to the at least one client device normally.

2. The information processing apparatus according to claim 1, comprising:

a receiving unit to receive a notification request, issued by the at least one client device to request the information processing apparatus to provide the event information to the at least one client device; and

a requesting client device list storage to include client device information concerning the at least one client device which issued the notification request,

wherein the event notifying information generating unit includes the client device information being included in the requesting client device list storage to generate the event notifying information concerning the event occurring in the information processing apparatus so that the event information of the event is provided to the at least one client device according to the client device information included in the event notifying information, when the event detecting unit detects the event.

3. The information processing apparatus according to claim 2, comprising:

a cancellation receiving unit to receive a cancellation request, issued by the at least one client device to cancel the notification request so that the information processing apparatus ceases providing the event information to the at least one client device; and

a client information removing unit to remove the client device information of the at least one client device which issued the cancellation request from the requesting client device list storage and the event notifying information so that the event information of the event is prevented from being provided to the at least one client device which issued the cancellation request.

4. The information processing apparatus according to claim 1,

wherein the event notifying information is stored in the event notifying information storage in the predetermined arrangement on the basis of an event type of the event occurring in the information processing apparatus.

5. The information processing apparatus according to claim 4,

wherein the event notifying information includes a counter to indicate number of the at least one client device being stored in the client information list storage on the event type basis;

and

wherein the information processing apparatus is provided with a first subtracting unit to subtract the number of the client device, which was provided with the event information normally from the number indicated in the counter, when the piece of the event information was provided to one of the at least one client device normally.

6. The information processing apparatus according to claim 5, comprising

an event information deleting system to delete the event notifying information, in which the number of the client device indicated in the counter is zero, from the event notifying information storage.

7. The information processing apparatus according to claim 1, comprising:

a client device information deleting unit to delete the client device information of the at least one client device, to which the piece of the event information was judged to be incapable of being provided, from the client information list storage and the event notifying information having the piece of the event information;

a second subtracting unit to subtract one from the number indicated in the counter in the event notifying information having the piece of the event information; and

a third subtracting unit to subtract one from the number indicated in the counter in the event notifying information which is arranged, in the predetermined order in the event notifying information storage, to follow the event notifying information, of which event information is judged to be incapable of being provided.

8. A method to control an image processing apparatus capable of monitoring a plurality of events which occur in the information processing apparatus and providing event information concerning each of the events to at least one client device which is communicable with the information processing apparatus, comprising:

detecting an event occurring in the information processing apparatus;

generating event notifying information, which includes the event information and information concerning the at least one client device to which the event information is provided;

storing the event notifying information in a predetermined arrangement in an event notifying information storage so that the event information concerning each of the events is provided to the at least one client device in chronological order in which the events occur according to the predetermined arrangement;

storing information concerning the at least one client device to which the event information is provided in a client information list storage;

providing a piece of the event information corresponding to a first event among the plurality of events to the at least one client device, of which information is stored in the client information list storage;

judging as to whether the piece of the event information was provided to the at least one client device normally; and

providing another piece of the event information corresponding to a second event among the plurality of events, which occurs subsequently to the first event, according to the event notifying information when the judging unit judges that the precedent piece of the event information was provided to the at least one client device normally.

9. The method according to claim 8, comprising:

receiving a notification request, issued by the at least one client device to request the information processing apparatus to provide the event information to the at least one client device; and

storing client device information concerning the at least one client device which issued the notification request in a requesting client device list storage; and

including the client device information being stored in the requesting client device list storage to generate the event notifying information concerning the event occurring in the information processing apparatus so that the event information of the event is provided to the at least one client device according to the client device information included in the event notifying information, when the event is detected.

10. The method according to claim 9, comprising:

receiving a cancellation request, issued by the at least one client device to cancel the notification request so that the information processing apparatus ceases providing the event information to the at least one client device; and
