New question #212686 on Graphite: https://answers.launchpad.net/graphite/+question/212686
I have a setup where I am receiving metrics via UDP from many hosts – see carbon.conf configuration file below. I need to rewrite some of the metric names before they are saved in the database. In reviewing the documentation, it is possible to do that via the rewrite-rules.conf, which requires that I first enable carbon aggregation. Since I am already receiving metrics via UDP, I would like to have the carbon aggregator to receive those via the UDP protocol, apply any rewrite rules, then store the metrics. In this case, the carbon aggregator is the same as my carbon cache host. In trying to get this to work, it does not look like carbon aggregator will start on a UDP port. When I have started and stopped the daemon, it never starts a service on the UDP port specified - I have looked at the log messages that get generated and 'ss -ua' command. Note: the aggregation-rules.conf and rewrite-rules.conf are files that exist, but they are empty – zero bytes. Questions: 1. Can the aggregator run on a UDP port? 2. Is my configuration file correct? 3. Anything else I should be looking at? carbon.conf file: [cache] LOCAL_DATA_DIR = /raid/whisper/ USER = carbon MAX_CACHE_SIZE = inf MAX_UPDATES_PER_SECOND = inf MAX_CREATES_PER_MINUTE = inf LINE_RECEIVER_INTERFACE = 0.0.0.0 LINE_RECEIVER_PORT = 2023 ENABLE_UDP_LISTENER = True UDP_RECEIVER_INTERFACE = 0.0.0.0 UDP_RECEIVER_PORT = 2023 PICKLE_RECEIVER_INTERFACE = 0.0.0.0 PICKLE_RECEIVER_PORT = 2004 USE_INSECURE_UNPICKLER = False CACHE_QUERY_INTERFACE = 0.0.0.0 CACHE_QUERY_PORT = 7002 USE_FLOW_CONTROL = True LOG_UPDATES = False WHISPER_AUTOFLUSH = False [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 = rules REPLICATION_FACTOR = 1 DESTINATIONS = 127.0.0.1:2004 MAX_DATAPOINTS_PER_MESSAGE = 500 MAX_QUEUE_SIZE = 10000 USE_FLOW_CONTROL = True [aggregator] LINE_RECEIVER_INTERFACE = 0.0.0.0 LINE_RECEIVER_PORT = 2003 PICKLE_RECEIVER_INTERFACE = 0.0.0.0 PICKLE_RECEIVER_PORT = 2024 ENABLE_UDP_LISTENER = True UDP_RECEIVER_INTERFACE = 0.0.0.0 UDP_RECEIVER_PORT = 2003 DESTINATIONS = 127.0.0.1:2023 REPLICATION_FACTOR = 1 MAX_QUEUE_SIZE = 10000 USE_FLOW_CONTROL = True MAX_DATAPOINTS_PER_MESSAGE = 500 MAX_AGGREGATION_INTERVALS = 5 Thanks, --Curt -- You received this question notification because you are a member of graphite-dev, which is an answer contact for Graphite. _______________________________________________ Mailing list: https://launchpad.net/~graphite-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~graphite-dev More help : https://help.launchpad.net/ListHelp
