How Log Pattern Extraction Works
Similar to automated log parsing algorithms (such as Drain or LogCluster), this utility tokenizes raw text streams and masks volatile values with generic placeholders to group recurring event templates.
1. IP & Host Masking
IPv4 addresses and subnets are generalized into the <IP> token.
2. Numeric & ID Masking
IDs, port numbers, response codes, and file sizes are replaced with <NUM> or <ID>.
3. Timestamp Normalization
Date strings and ISO timestamps are collapsed into standard <TIMESTAMP> tokens.
