Real-time viewing tool for compressed log data

Abstract

Techniques are provided for decompression of compressed log data, such as for a real-time viewing of compressed log data. An exemplary method comprises: obtaining a compressed log file comprised of a plurality of compressed log messages, wherein a given compressed log message is comprised of one or more message variables and a message signature corresponding to a message template of the given compressed log message; and presenting a first subset of the compressed log file by translating, in memory, the message templates of the compressed log messages within the first subset to corresponding message signatures using a decompression index that maps a plurality of the message signatures to corresponding message templates. The first subset of the compressed log file optionally comprises a predefined number of lines surrounding a requested line of the compressed log file. In further variations, at least one additional subset of the compressed log file is precomputed using the disclosed decompression techniques.
