# radiusd template by erdnaxe@crans.org

# Define the exported metric names.  The `by' keyword indicates the metric has
# dimensions.  For example, `request_total' counts the frequency of each
# request's "command".  The name `command' will be exported as the label name
# for the metric.  The command provided in the code below will be exported as
# the label value.

# The `syslog' decorator defines a procedure.  When a block of mtail code is
# "decorated", it is called before entering the block.  The block is entered
# when the keyword `next' is reached.
