About each properties

property	description
stage	The deployment stage with serverless. Because only one subscription filter can be set for one LogGroup.
logGroupName	The log group to associate with the subscription filter.
filterPattern	The filtering expressions that restrict what gets delivered to the destination AWS resource. Sorry, if you want to use '{ $.xxx = "yyy" }' syntax, then surround the whole in ''(single quote).
