Method and system for compressing logs

摘要

A computer-implemented method to compress log messages is disclosed. The method starts with maintaining a log reference table having a plurality of log reference entries, each containing a string of characters to be recited repeatedly during logging of messages. In response to a request for logging a log message initiated from an application, the method creates a compressed log message entry in a compressed log file. The compressed log message entry includes: a time stamp indicating the time the log message being created; a log reference identifier identifying one of the plurality of log reference entries without reciting a corresponding string of characters of the log reference entry, where the one of the plurality of log reference entries contains one or more variable indications; and a log variable portion associated with the log message, where the log variable portion contains a part of the log message.

1. A computer-implemented method for compressing log messages, the method comprising:
maintaining, by a log reference processor, a log reference table having a plurality of log reference entries, each containing a string of characters to be recited repeatedly during logging of messages that are generated from an application during its execution, each string of characters describing a predetermined event, wherein maintaining a log reference table includes:
parsing, by the log reference processor, the application to determine a log reference entry not already in the log reference table, andstoring the log reference entry in the log reference table; and in response to a request for logging a log message initiated from the application, creating, by a log encoder, a compressed log message entry in a compressed log file, the compressed log message entry including:
a time stamp indicating the time the log message being created,a log reference identifier identifying one of the plurality of log reference entries without reciting a corresponding string of characters of the log reference entry, wherein the one of the plurality of log reference entries contains one or more variable indications, anda log variable portion associated with the log message, wherein the log variable portion contains a part of the log message, wherein the compressed log message is to describe via the identified log reference entry an event that occurred during operations of the application.
