## Telegraf tag to use as a routing key
## ie, if this tag exists, its value will be used as the routing key
## The routing tag specifies a tagkey on the metric whose value is used as
## the message key. The message key is used to determine which partition to
## send the message to. This tag is prefered over the routing_key option.
routing_tag = "host"
## Static routing key. Used when no routing_tag is set or as a fallback
## when the tag specified in routing tag is not found. If set to "random",
## a random value will be generated for each message.
## The routing key is set as the message key and used to determine which
## partition to send the message to. This value is only used when no
## routing_tag is set or as a fallback when the tag specified in routing tag
## is not found.
##
## If set to "random", a random value will be generated for each message.
##
## When unset, no message key is added and each message is routed to a random
## partition.
##
## ex: routing_key = "random"
## routing_key = "telegraf"
# routing_key = ""
