New question #242717 on Graphite:
https://answers.launchpad.net/graphite/+question/242717

I'm trying to do a setup of two carbon-cache and one carbon-relay on the same machine.

I can send metrics to both the carbon-caches and it works.
But when I'm sending metrics to the relay it doesn't forward it to the caches.

Anyone have any ideas of why it isn't working?

Here is the carbon.conf:
[cache]
ENABLE_LOGROTATION = True
USER =
MAX_CACHE_SIZE = inf
MAX_UPDATES_PER_SECOND = 60
MAX_UPDATES_PER_SECOND_ON_SHUTDOWN = 500
MAX_CREATES_PER_MINUTE = 50

LINE_RECEIVER_INTERFACE = 0.0.0.0
LINE_RECEIVER_PORT = 2003
ENABLE_UDP_LISTENER = False

UDP_RECEIVER_INTERFACE = 0.0.0.0
UDP_RECEIVER_PORT = 2003
PICKLE_RECEIVER_INTERFACE = 0.0.0.0
PICKLE_RECEIVER_PORT = 2004
LOG_LISTENER_CONNECTIONS = True
USE_INSECURE_UNPICKLER = False
CACHE_QUERY_INTERFACE = 0.0.0.0
CACHE_QUERY_PORT = 7002
USE_FLOW_CONTROL = True
LOG_UPDATES = True
LOG_CACHE_HITS = False
LOG_CACHE_QUEUE_SORTS = True
CACHE_WRITE_STRATEGY = sorted
WHISPER_AUTOFLUSH = False
WHISPER_FALLOCATE_CREATE = True

[cache:b]
LINE_RECEIVER_PORT = 2103
PICKLE_RECEIVER_PORT = 2104
CACHE_QUERY_PORT = 7102

[relay]
LINE_RECEIVER_INTERFACE = 0.0.0.0
LINE_RECEIVER_PORT = 2013
PICKLE_RECEIVER_INTERFACE = 0.0.0.0
PICKLE_RECEIVER_PORT = 2014
RELAY_METHOD = consistent-hashing
REPLICATION_FACTOR = 0
DESTINATIONS = 127.0.0.1:2004:a, 127.0.0.1:2104:b
MAX_DATAPOINTS_PER_MESSAGE = 500
MAX_QUEUE_SIZE = 10000
USE_FLOW_CONTROL = True

[aggregator]
LINE_RECEIVER_INTERFACE = 0.0.0.0
LINE_RECEIVER_PORT = 2023
PICKLE_RECEIVER_INTERFACE = 0.0.0.0
PICKLE_RECEIVER_PORT = 2024
FORWARD_ALL = True
DESTINATIONS = 127.0.0.1:2004
REPLICATION_FACTOR = 1
MAX_QUEUE_SIZE = 10000
USE_FLOW_CONTROL = True
MAX_DATAPOINTS_PER_MESSAGE = 500
MAX_AGGREGATION_INTERVALS = 5

Can't restart carbon-cache-a because data is feeded to it at the moment. And it is running with all the LOG_settings set to False.

PS.
And if I got it right, then these settings should make the carbon-relay to split the metrics across the carbon-caches
