Normalization was a necessity in the early days of SIEM, when storage and compute power were expensive commodities, and SIEM platforms used relational database management systems for back-end data management. However, you need to extract your timestamp with the 'norm' command first, place it in a variable, and then pipe the variable as input to the 'eval' function above. Data Normalization is a process of reorganizing information in a database to meet two requirements: data is only stored in one place (reducing the data) and all related data items are sorted together. Parsers are built as KQL user-defined functions that transform data in existing tables, such as CommonSecurityLog, custom logs tables, or Syslog, into the normalized schema.
