inferredTokenName

A name that CloudWatch Logs assigned to this dynamic token to make the pattern more readable. The string part of the inferredTokenName gives you a clearer idea of the content of this token. The number part of the inferredTokenName shows where in the pattern this token appears, compared to other dynamic tokens. CloudWatch Logs assigns the string part of the name based on analyzing the content of the log events that contain it.

For example, an inferred token name of IPAddress-3 means that the token represents an IP address, and this token is the third dynamic token in the pattern.
