Method and computing device for recording log entries
A method, computing device and computer program product are provided to maintain a comprehensive record of log entries, even in an instance in which the recordation of log entries to the primary log temporarily fails. In the context of a method, one or more log entries are written to a primary log. The method also includes determining that writing a log entry to the primary log has failed and writing the log entry to a fallback log in an instance in which writing the log entry to the primary log has failed. The method further includes performing a restoration process. The restoration process includes determining whether the log entry written to the fallback log is able to be written to the primary log. If so, the restoration process writes one or more log entries written to the fallback log to the primary log. If not, the restoration process is repeated.
1. A method of recording log entries comprising:
writing one or more log entries to a primary log;
determining that writing a log entry to the primary log has failed;
writing the log entry to a fallback log in an instance in which writing the log entry to the primary log has failed; and
performing, with a processor, a restoration process comprising:
determining whether the log entry written to the fallback log is able to be written to the primary log by attempting to write the log entry written to the fallback log to the primary log;
in an instance in which the log entry written to the fallback log is able to be written to the primary log, writing one or more log entries written to the fallback log to the primary log by executing a plurality of tasks to asynchronously write a plurality of log entries written to the fallback log to the primary log; and
in an instance in which the log entry written to the fallback log is unable to be written to the primary log, repeating the restoration process.
2. A method of claim 1 wherein the primary log comprises a remote system and the fallback log comprises a local storage device.
3. A method of claim 1 wherein in an instance in which the log entry written to the fallback log is able to be written to the primary log, performing the restoration process further comprises deleting one or more log entries from the fallback log once the one or more log entries are written to the primary log.
4. A method of claim 1 wherein writing one or more log entries written to the fallback log to the primary log in an instance in which the log entry written to the fallback log is able to be written to the primary log comprises asynchronously executing the plurality of tasks with each task configured to write a log entry written to the fallback log to the primary log.
5. A method of claim 1 further comprising requesting access to the fallback log and wherein performing the restoration process comprises performing the restoration process contingent upon granting of access to the fallback log.
6. A method of claim 5 wherein performing the restoration process further comprises:
securing exclusive rights to the fallback log upon granting of access to the fallback log; and
relinquishing the exclusive rights to the fallback log in an instance in which the restoration process is complete.
7. A computer program product for recording log entries, the computer program product comprising a non-transitory computer readable medium having program code stored thereon, the program code comprising program code instructions configured, upon execution, to perform the method of claim 1 .
8. A computer program product of claim 7 wherein ire an instance in which the log entry written to the fallback log is able to be written to the primary log, the program code instructions configured to perform the restoration process are further configured to delete one or more log entries from the fallback log once the one or more log entries are written to the primary log.
9. A computer program product of claim 7 wherein the program code instructions configured to write one or more log entries written to the fallback log to the primary log in an instance in which the log entry written to the fallback log is able to be written to the primary log comprise program code instructions configured to asynchronously execute the plurality of tasks with each task configured to write a log entry written to the fallback log to the primary log.
10. A computer program product of claim 7 wherein the program code further comprises program code instructions configured to request access to the fallback log and wherein the program code instructions are configured to perform the restoration process by performing the restoration process contingent upon granting of access to the fallback log.
11. A computer program product of claim 10 wherein the program code instructions configured to perform the restoration process further comprise program code instructions configured to:
secure exclusive rights to the fallback log upon granting of access to the fallback log; and
relinquish the exclusive rights to the fallback log in an instance in which the restoration process is complete.
12. A computing device for recording log entries, the computing device comprising processing circuitry configured to:
write one or more log entries to a primary log;
determine that writing a log entry to the primary log has failed;
write the log entry to a fallback log in an instance in which writing the log entry to the primary log has failed; and
perform a restoration process comprising:
determining whether the log entry written to the fallback log is able to be written to the primary log by attempting to write the log entry written to the fallback log to the primary log;
in an instance in which the log entry written to the fallback log is able to be written to the primary log, writing one or more log entries written to the fallback log to the primary log by executing a plurality of tasks to asynchronously write a plurality of log entries written to the fallback log to the primary log; and
in an instance in which the log entry written to the fallback log is unable to be written to the primary log, repeating the restoration process.
13. A computing device of claim 12 wherein the primary log comprises a remote system and the fallback log comprises a local storage device.
14. A computing device of claim 12 wherein in an instance in which the log entry written to the fallback log is able to be written to the primary log, the processing circuitry is further configured to perform the restoration process by deleting one or more log entries from the fallback log once the one or more log entries are written to the primary log.
15. A computing device of claim 12 wherein the processing circuitry is configured to write one or more log entries written to the fallback log to the primary log in an instance in which the log entry written to the fallback log is able to be written to the primary log by asynchronously executing the plurality of tasks with each task configured to write a log entry written to the fallback log to the primary log.
16. A computing device of claim 12 wherein the processing circuitry is further configured to request access to the fallback log and wherein the processing circuitry is configured to perform the restoration process by performing the restoration process contingent upon granting of access to the fallback log.
17. A computing device of claim 16 wherein the processing circuitry is configured to perform the restoration process by:
securing exclusive rights to the fallback log upon granting of access to the fallback log; and
relinquishing the exclusive rights to the fallback log in an instance in which the restoration process is complete.
18. A computing device for recording log entries, the computing device comprising processing circuitry configured to:
write one or more log entries to a primary log;
determine that writing a log entry to the primary log has failed;
write the log entry to a fallback log in an instance in which writing the log entry to the primary log has failed;
request access to the fallback log; and
contingent upon granting of access to the fallback log, perform a restoration process comprising:
determining whether the log entry written to the fallback log is able to be written to the primary log;
in an instance in which the log entry written to the fallback log is able to be written to the primary log, writing one or more log entries written to the fallback log to the primary log; and
