LogPattern

An object that defines the log patterns that belongs to a LogPatternSet.

Contents

Pattern

A regular expression that defines the log pattern. A log pattern can contain as many as 50 characters, and it cannot be empty. The pattern must be DFA compatible. Patterns that utilize forward lookahead or backreference constructions are not supported.

Required: No

Rank

Rank of the log pattern. Must be a value between 1 and 1,000,000. The patterns are sorted by rank, so we recommend that you set your highest priority patterns with the lowest rank. A pattern of rank 1 will be the first to get matched to a log line. A pattern of rank 1,000,000 will be last to get matched. When you configure custom log patterns from the console, a Low severity pattern translates to a 750,000 rank. A Medium severity pattern translates to a 500,000 rank. And a High severity pattern translates to a 250,000 rank. Rank values less than 1 or greater than 1,000,000 are reserved for AWS-provided patterns.

Type: Integer

Required: No
