Logram: Efficient Log Parsing Using n-Gram Dictionaries

Understand

Software systems usually record important runtime information in their logs.

• Logs help practitioners understand system runtime behaviors and diagnose field failures.
• As logs are usually very large in size, automated log analysis is needed to assist practitioners in their software operation and maintenance efforts.
• Typically, the first step of automated log analysis is log parsing, i.e., converting unstructured raw logs into structured data.
