Match Semantics

Content matchers interpret match strings using these simple rules.

  • If the match string specifies a field with boolean token true, that field must be present in the message in order to match.
  • If the match string specifies a field with boolean token false, that field must be absent from the message in order to match.
  • If the match string specifies a field with either a string or long integer value, that field must be present in the message with that value.
  • When comparing a field name or a value, all comparisons must be exact. Matching does not support wildcards nor regular expressions.
