# The go, java and python multiline parsers referenced by the multiline
# filter above are built into Fluent Bit. .NET is not, so it is defined
# here as a custom parser. A .NET stack trace starts with a line that
# ends in "Exception: <message>" and continues with " at ..." frames and
# "--- End of ... stack trace ---" markers.
#
# To support another log format not covered by the built-ins, add a
# [MULTILINE_PARSER] here (type regex) and append its name to
# `multiline.parser` on the multiline filter. See
# https://docs.fluentbit.io/manual/data-pipeline/filters/multiline-stacktrace
