Pattern Layout support #746
Description
I am not sure if the current com.google.cloud.logging.logback.LoggingAppender support a Pattern Layout, incase if there's a requirment to mask logs. Have given a sample logback config that does the masking.
<encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
<layout class="com.test.logback.MaskingPatternLayout">
<maskPattern>\"SSN\"\s*:\s*\"(.*?)\"</maskPattern> <!-- SSN JSON pattern -->
<pattern>%-5p [%d{ISO8601,UTC}] [%thread] %c: %m%n%rootException</pattern>
</layout>
</encoder>
