Abstract

A method for logging trace events of a network device in a network is described herein. A plurality of log events may be generated based on a source level. The plurality of log events is stored to a log buffer of the network device. The log buffer is monitored for a trigger event, which is a condition in the network. It is determined whether the trigger event is detected. Upon detecting the trigger event, one or more log events of the plurality of log events in an ex-ante window of the log buffer are determined. A log event of the one or more log events is provided to a system log. Upon determining the trigger event is not detected, it is determined whether the one or more log events of the plurality of log events in the ex-ante window satisfy a log level. A severity of the source level is lower than a severity of the log level.

Claims

1. A method for logging trace events of a network device in a network, the method comprising:

generating, by the network device, a plurality of log events based on a source level;

storing the plurality of log events to a log buffer of the network device;

monitoring the log buffer for a trigger event, wherein the trigger event is a condition in the network;

determining whether the trigger event is detected;

determining one or more log events of the plurality of log events in an ex-ante window of the log buffer upon detecting the trigger event;

providing a log event of the one or more log events to a system log; and

determining whether the one or more log events of the plurality of log events in the ex-ante window satisfy a log level upon determining the trigger event is not detected, wherein a severity of the source level is lower than a severity of the log level.

2. The method of claim 1, wherein the system log is a local system log of the network device.

3. The method of claim 1, further comprising:

determining one or more log events of the plurality of log events in an ex-post window of the log buffer based on the source level; and

providing a log event of the one or more log events in the ex-post window to a system log.

4. The method of claim 1, further comprising:

reconfiguring the source level;

determining one or more log events of the plurality of log events in an ex-post window of the log buffer based on the reconfigured source level; and

providing a log event of the one or more log events in the ex-post window to a system log.

5. The method of claim 4, wherein reconfiguring the source level includes modifying a severity of the source level.

6. The method of claim 4, wherein determining the one or more log events in the ex-post window is performed for a time period.

7. The method of claim 4, wherein determining the one or more log events in the ex-post window is performed until a normal flow of log events is detected.

8. The method of claim 1, wherein the source level is reconfigured based on a type of the detected trigger event.

9. The method of claim 1, wherein the network device is a network infrastructure device, further comprising:

transmitting a broadcast message across the network, wherein the broadcast message triggers a receiving network device to provide to a system log one or more log events in a log buffer of the receiving device.

10. A system for logging trace events of a network device in a network, the system comprising:

a processor; and

a memory coupled to the processor, the memory configured to store an electronic document;

wherein the processor is configured to;

generate a plurality of log events based on a source level;

store the plurality of log events to a log buffer of the network device;

monitor the log buffer for a trigger event, wherein the trigger event is a condition in the network;

determine whether the trigger event is detected;

determine one or more log events of the plurality of log events in an ex-ante window of the log buffer upon detecting the trigger event;

provide a log event of the one or more log events to a system log; and

determine whether the one or more log events of the plurality of log events in the ex-ante window satisfy a log level upon determining the trigger event is not detected, wherein a severity of the source level is lower than a severity of the log level.

11. The system of claim 10, wherein the system log is a local system log of the network device.

12. The system of claim 10, wherein the processor is configured to:

determine one or more log events of the plurality of log events in an ex-post window or the log buffer based on the source level; and

provide a log event of the one or more log events in the ex-post window to a system log.

13. The system of claim 10, wherein the processor is configured to:

reconfigure the source level;

determine one or more log events of the plurality of log events in an ex-post window of the log buffer based on the reconfigured source level; and

provide a log event of the one or more log events in the ex-post window to a system log.

14. The system of claim 10, wherein the processor is configured to:

transmit a broadcast message across the network, wherein the broadcast message triggers a receiving network device to provide to a system log one or more log events in a log buffer of the receiving device.

15. A computer-readable medium storing a plurality of instructions for controlling a data processor for logging trace events of a network device in a network, the plurality of instructions comprising:

instructions that cause the data processor to generate a plurality of log events based on a source level;

instructions that cause the data processor to store the plurality of log events to a log buffer of the network device;

instructions that cause the data processor to monitor the log buffer for a trigger event, wherein the trigger event is a condition in the network;

instructions that cause the data processor to determine whether the trigger event is detected;

instructions that cause the data processor to determine one or more log events of the plurality of log events in an ex-ante window of the log buffer upon detecting the trigger event;

instructions that cause the data processor to provide a log event of the one or more log events to a system log; and

instructions that cause the data processor to determine whether the one or more log events of the plurality of log events in the ex-ante window satisfy a log level upon determining the trigger event is not detected, wherein a severity of the source level is lower than a severity of the log level.

16. The computer-readable medium of claim 15, wherein the system log is a local system log of the network device.

17. The computer-readable medium of claim 15, wherein the plurality of instructions further comprise:

instructions that cause the data processor to determine one or more log events of the plurality of log events in an ex-post window of the log buffer based on the source level; and

18. The computer-readable medium of claim 15, wherein the plurality of instructions further comprise:

instructions that cause the data processor to reconfigure the source level;

instructions that cause the data processor to determine one or more log events of the plurality of log events in an ex-post window of the log buffer based on the reconfigured source level; and

instructions that cause the data processor to provide a log event of the one or more log events in the ex-post window to a system log.

19. The computer-readable medium of claim 18, wherein the source level is reconfigured based on a type of the detected trigger event.

20. The computer-readable medium of claim 15, wherein the plurality of instructions further comprise instructions that cause the data processor to transmit a broadcast message across the network, wherein the broadcast message triggers a receiving network device to provide to a system log one or more log events in a log buffer of the receiving device.
