Proposed title of this feature request

Add support to count pattern matches and apply comparison operator on it

What is the nature and description of the request?

Customer would like to count number of occurrences of matching pattern, so they can take action accordingly.

Why does the customer need this? (List the business requirements here)

Customer has thousands of applications that they want to scan to find which applications are generating multiple (>1)  log files, so that they can tag log statements based on original log file name  and  direct them to stdout during containerization.

For example count the "pattern: ((Daily)?Rolling)?FileAppender" in log4j2.xml to verify if the app is writing to multiple log files and suggest appropriate updates in MTA custom rule to fix it.
