Abstract

Methods, systems and apparatuses for logging diagnostic information are disclosed. In accordance with one method, first diagnostic information is logged in a router in accordance with a first mode having a first logging rate. In addition, an operational problem within the router is detected. Further, in response to detecting the operational problem, second diagnostic information is logged in accordance with a second mode having a second logging rate that is greater than the first logging rate of the first mode.

Claims

1. A method comprising:

logging first diagnostic information in a router in accordance with a first mode having a first logging rate;

detecting an operational problem within the router; and

in response to detecting the operational problem, logging second diagnostic information in accordance with a second mode in which a second logging rate of said second mode is greater than the first logging rate of said first mode.

2. The method of claim 1, wherein said operational problem is at least one of a freeze of said router or a reboot performed in response to said freeze.

6. The method of claim 1, further comprising:

repairing the operational problem based on said logged second diagnostic information.

7. The method of claim 6, wherein said repairing further comprises altering at least one of said first logging rate or said second logging rate based on said logged second diagnostic information.

8. The method of claim 6, wherein said first mode includes a first maximum number of writes that limits said logging first diagnostic information, wherein said second mode includes a second maximum number of writes that limits said logging second diagnostic information and wherein said repairing further comprises altering at least one of said first maximum number of writes or said second maximum number of writes based on said logged second diagnostic information.

3. The method of claim 3, wherein said second diagnostic information is different from said first diagnostic information.

4. The method of claim 3, wherein said second diagnostic information includes at least one of firewall logs, local area network (LAN) dynamic host configuration protocol (DHCP) transactions, interface settings logs or Internet Gateway Management Protocol (IGMP) logs.

5. The method of claim 4, wherein said first diagnostic information excludes at least one of firewall logs, LAN DHCP transactions, Interface settings logs or IGMP logs.

9. An apparatus comprising:

a controller configured to log first diagnostic information in a router in accordance with a first mode and to detect an operational problem within the router; and

a communication interface configured to transmit an indication of the operational problem and to remotely receive instructions to log second diagnostic information in the router in accordance with a second mode,

wherein the controller is further configured to log the second diagnostic information in accordance with the second mode in response to receipt of said instructions and wherein said second diagnostic information is composed of a larger amount of data than said first diagnostic information.

10. The apparatus of claim 9, wherein the controller is further configured to log said second diagnostic information in accordance with the second mode at a logging rate that is greater than a logging rate of logging said first diagnostic information in accordance with the first mode.

11. The apparatus of claim 9, wherein the controller is further configured to direct the communication interface to transmit the second diagnostic information and wherein the controller is further configured to repair the router in accordance with repair instructions remotely received through said communication interface.

12. The apparatus of claim 11, wherein the controller is further configured to alter at least one of a logging rate at which said second diagnostic information is logged in accordance with the second mode or a logging rate at which said first diagnostic information is logged in accordance with the first mode based on said repair instructions.

13. The apparatus of claim 11, wherein said first mode includes a first maximum number of writes that limits logging of said first diagnostic information by said controller, wherein said second mode includes a second maximum number of writes that limits logging said second diagnostic information by said controller and wherein said controller is further configured to alter at least one of said first maximum number of writes or said second maximum number of writes based on said repair instructions.

14. The apparatus of claim 9, wherein said second diagnostic information is different from said first diagnostic information and wherein said operational problem is at least one of a freeze of said router or a reboot performed in response to said freeze.

15. A system comprising:

a communication interface configured to remotely receive an indication of an operational problem at a router; and

a controller configured to direct the communication interface to transmit instructions to the router that direct the router to switch a logging mode from a first mode to a second mode, wherein first diagnostic information is logged at said router in accordance with said first mode, wherein second diagnostic information is logged at said router in accordance with said second mode and wherein said second diagnostic information is composed of a larger amount of data than said first diagnostic information.

16. The system of claim 15, wherein said second diagnostic information is logged at said router in accordance with said second mode at a logging rate that is greater than a logging rate at which said first diagnostic information is logged at said router in accordance with said first mode.

17. The system of claim 15, wherein the communication interface is configured to remotely receive said second diagnostic information from said router and wherein said system further comprises:

a repair module configured to determine repair instructions based on said second diagnostic information and to direct the communication interface to remotely transmit said repair instructions to said router.

18. The system of claim 17, wherein said controller is further configured to add instructions to said repair instructions that direct the router to alter at least one of a logging rate at which said second diagnostic information is logged in accordance with the second mode or a logging rate at which said first diagnostic information is logged in accordance with the first mode based on said second diagnostic information.

19. The system of claim 17, wherein said first mode includes a first maximum number of writes that limits logging of said first diagnostic information, wherein said second mode includes a second maximum number of writes that limits logging of said second diagnostic information and wherein said controller is further configured add instructions to said repair instructions that direct the router to alter at least one of said first maximum number of writes or said second maximum number of writes based on said second diagnostic information.

20. The system of claim 15, wherein said second diagnostic information is different from said first diagnostic information and wherein said operational problem is at least one of a freeze of said router or a reboot performed in response to said freeze.
