ABSTRACT:
A log list comprising log identifiers is received, wherein the log list delineates a set of logs to be groomed. A log sequence number and a time-stamp are extracted from the first log record of each log in the set of logs. A system ID is extracted from a log record of each log in the set of logs. An appended log list is created wherein the system ID, time-stamp and log sequence number comprise appended information that is logically appended to each of respective ones of the log identifiers. The appended log list is sorted utilizing at least a portion of the appended information, the result comprising a sorted appended log list. An actual log sequence number is extracted from the last log record of each log in the set of logs. Each of the actual log sequence numbers is compared to a corresponding predicted log sequence number, wherein the corresponding predicted log sequence number is computed utilizing the sorted appended log list. A report is generated wherein range information reflecting all discrepancies between the actual log sequence numbers and the corresponding predicted log sequence numbers are disclosed.
