Abstract

Methods (as well as apparatus and software that implement the methods) of remote information logging and selective reflections of loggable information are disclosed. One such method comprises: receiving a notice of locally-originated loggable information; determining whether said information satisfies a first criterion; and notifying, if said first criterion is satisfied, a remote logger service of said information. Another such method comprises: receiving multiple instances of remotely-originated loggable information; and making entries in a local log for said multiple instances of remotely-originated loggable information. And yet another such method comprises: providing access to a local log of remotely-originated information; determining whether information corresponding to an entry in said local log satisfies a first criterion; and notifying, if said first criterion is satisfied, a remote service of said information.

Claims

1. A method of logging information, the method comprising:

receiving a notice of locally-originated loggable information;

determining whether said information satisfies a first criterion; and

notifying, if said first criterion is satisfied, a remote logger service of said information.

2. The method of claim 1, further comprising:

making an entry in a local log for the information corresponding to said notice.

3. The method of claim 2, the method further comprising:

determining, before said step of making an entry, whether said information satisfies a second criterion different than said first criterion;

wherein said step of making an entry is contingent upon said second criterion having been satisfied.

4. The method of claim 3, wherein and said step of notifying is contingent upon said second criterion having been satisfied.

5. The method of claim 3, wherein said first criterion and said second criterion are respective levels of information priority.

6. The method of claim 5, wherein:

a scheme of said information priority assigns smaller numbers to higher priority information and larger numbers to lower priority information, the highest priority information having priority number zero; and

the first criterion is that an information must be lower in priority number than a first predetermined value, and said second criterion is that an information must be lower in priority number than a second predetermined value.

7. The method of claim 6, wherein said first predetermined value is smaller than said second predetermined value.

8. The method of claim 1, wherein said remote logger is of such remoteness as to include a storage area network (“

SAN”

) as part of a communication path thereto.

9. The method of claim 1, wherein said first criterion is a level of information priority.

24. An apparatus operable to perform the method of claim 1.

25. A computer-readable medium having code portions embodied thereon that, when read by a processor, cause said processor to perform the method of claim 1.

26. The computer-readable medium of claim 25, wherein said code portions are configured to adhere to JINI distributed computing technology or JCORE distributed computing technology.

10. A method of logging information, the method comprising:

receiving a notice of locally-originated loggable information;

determining whether said information satisfies a logging criterion;

making an entry, where said logging criterion is satisfied, in a local log for the information corresponding to said notice;

determining whether said information satisfies a reflection criterion different than said first criterion; and

notifying, if said reflection criterion is satisfied, a remote logger service of said information.

11. A method of logging information, the method comprising:

receiving multiple instances of remotely-originated loggable information; and

making entries in a local log for said multiple instances of remotely-originated loggable information.

12. The method of claim 11, wherein at least two of said instances of remotely-originated loggable information originate from sources having clocks that are out of sync such that an overall order of occurrence among all of said instances of loggable information is obscured;

the method further comprising;

approximating an order of occurrence among all of said instances of loggable information;

wherein said step of making entries makes said entries according to the approximated order of occurrence.

13. The method of claim 12, wherein said step of approximating includes:

time-stamping each receipt of said remotely-originated loggable information with a corresponding receipt time according to a clock local to the point of receipt;

wherein said step of making entries arranges said entries in order of the respective time stamps.

14. The method of claim 11, wherein each of said instances of instances of remotely-originated loggable information was logged locally before having been sent to the point of receipt.

15. The method of claim 11, the method further comprising:

determining, for each entry in said local log, whether information corresponding to said entry satisfies a first criterion; and

notifying, if said first criterion is satisfied, a remote service of said information.

16. The method of claim 15, wherein said remote service is of such remoteness as to include a storage area network (“

SAN”

) as part of a communication path thereto.

17. The method of claim 11, wherein at least one source of said remotely-originated loggable information is of such remoteness as to include a storage area network (“

SAN”

) as part of a communication path thereto.

27. An apparatus operable to perform the method of claim 11.

28. A computer-readable medium having code portions embodied thereon that, when read by a processor, cause said processor to perform the method of claim 11.

29. The computer-readable medium of claim 28, wherein said code portions are configured to adhere to JINI distributed computing technology or JCORE distributed computing technology.

18. A method of logging information, the method comprising:

receiving multiple instances of remotely-originated loggable information; and

wherein at least two of said instances of remotely-originated loggable information originate from sources having clocks that are out of sync such that an overall order of occurrence among all of said instances of loggable information is obscured;

approximating an order of occurrence among all of said instances of loggable information by time-stamping each receipt of said remotely-originated loggable information with a corresponding receipt time according to a clock local to the point of receipt;

making entries in a local log by arranging said entries in order of the respective time stamps.

19. A method of logging information, the method comprising:

providing access to a local log of remotely-originated information;

determining whether information corresponding to an entry in said local log satisfies a first criterion; and

notifying, if said first criterion is satisfied, a remote service of said information.

20. The method of claim 19, wherein said remote service is at least one of a support provider or a maintenance provider.

21. The method of claim 19, wherein said remote service is of such remoteness as to include the Internet as part of a communication path thereto.

22. The method of claim 19, wherein each instance of said remotely-originated information was logged locally before being sent to the point of receipt.

30. An apparatus operable to perform the method of claim 19.

31. A computer-readable medium having code portions embodied thereon that, when read by a processor, cause said processor to perform the method of claim 19.

32. The computer-readable medium of claim 31, wherein said code portions are configured to adhere to JINI distributed computing technology or JCORE distributed computing technology.

23. A method of logging information, the method comprising:

providing access to a local log of remotely-originated information, each instance of said remotely-originated information having been logged locally before being sent to the point of receipt;

determining whether information corresponding to an entry in said local log satisfies a first criterion; and

notifying, if said first criterion is satisfied, a remote service of said information, wherein said remote service is at least one of a support provider or a maintenance provider;

wherein said remote service is of such remoteness as to include the Internet as part of a communication path thereto.
