# Log PS Explained ### Log Pattern-Signature (PS) Explained Machine logs are known to be difficult to process due to their mixed structured/none-structured nature. The non-conforming log format and its volume growth make it challenging to extract values using conventional search and monitoring classic techniques. Apica Ascent normalizes all incoming logs into Pattern-Signature (PS). PS groups or clusters for all the ingested logs based on their underlying logging structure for any log forms. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
