+# The mainnet does not include the network magic into addresses. Testnets do.
+RequiresNetworkMagic: RequiresNoMagic
+
+##### Update system parameters #####
+
+# This protocol version number gets used by block producing nodes as part
+# of the system for agreeing on and synchronising protocol updates.
+#
+# See https://github.com/input-output-hk/cardano-node/blob/master/cardano-node/src/Cardano/Node/Protocol/Cardano.hs#L199

+# We do this only for Byron compatibility now.

+ApplicationVersion: 1
+
+##### Logging configuration #####
+
+# Enable or disable logging overall
+TurnOnLogging: True
+
+# Enable the collection of various OS metrics such as memory and CPU use.
+# These metrics are traced in the context name: 'cardano.node.metrics' and can
+# be directed to the logs or monitoring backends.
+TurnOnLogMetrics: True
+
+# Global logging severity filter. Messages must have at least this severity to
+# pass. Typical values would be Warning, Notice, Info or Debug.
+minSeverity: Info
+
+# Log items can be rendered with more or less verbose detail.
+# Verbosity ranges from MinimalVerbosity, NormalVerbosity to MaximalVerbosity
+TracingVerbosity: NormalVerbosity
+
+# The system supports a number of backends for logging and monitoring.
+# This setting lists the backends that will be available to use in the
+# configuration below. The logging backend is called Katip.
+setupBackends:
+  - KatipBK
+
+# This specifies the default backends that trace output is sent to if it
+# is not specifically configured to be sent to other backends.
+defaultBackends:
+  - KatipBK
+
+# EKG is a simple metrics monitoring system. Uncomment the following to enable
+# this backend and listen on the given local port and point your web browser to
+# http://localhost:12788/
+hasEKG: 12788
+
+# The Prometheus monitoring system exports EKG metrics. Uncomment the following
+# to listen on the given port. Output is provided on
+# http://localhost:12789/metrics
+# hasPrometheus:
+#   - "127.0.0.1"
+#   - 12789
+
+# To enable the 'TraceForwarder' backend, uncomment the following setting. Log
+# items are then forwarded based on an entry in 'mapBackends' to a separate
+# process running a 'TraceAcceptor'.
+# Example using UNIX pipes:
+# traceForwardTo:
+#   tag: RemotePipe
+#   contents: "logs/pipe"
+#
+# Example using Windows named pipes:
+# traceForwardTo:
+#   tag: RemotePipe
+#   contents: "\\\\.\\pipe\\acceptor"
+#
+# Example using network socket:
+# traceForwardTo:
+#   tag: RemoteSocket
+#   contents:
+#     - "127.0.0.1"
+#     - "2997"
+
+# For the Katip logging backend we must set up outputs (called scribes)
+# The available types of scribe are:
+#   FileSK for files
+#   StdoutSK/StderrSK for stdout/stderr
+#   JournalSK for systemd's journal system
+#   DevNullSK ignores all output
+# The scribe output format can be ScText or ScJson. Log rotation settings can
+# be specified in the defaults below or overidden on a per-scribe basis here.
+setupScribes:
+  - scKind: StdoutSK
+    scName: stdout
+    scFormat: ScText
+    scRotation: null
+
+# For the Katip logging backend this specifies the default scribes that trace
+# output is sent to if it is not configured to be sent to other scribes.
+defaultScribes:
+  - - StdoutSK
+    - stdout
+
+# The default file rotation settings for katip scribes, unless overridden
+# in the setupScribes above for specific scribes.
+rotation:
+  rpLogLimitBytes: 5000000

+
+##### Fine grained logging control #####
+
+# It is also possible to have more fine grained control over filtering of

+# This is less efficient than the coarse trace filters above but provides
+# much more precise control.
+

+  # This routes metrics matching specific names to particular backends.

+  # an override and not an extension so anything matched here will not
+  # go to the default backend, only to the explicitly listed backends.
