version 0.12.0
  • Tags support was added (only with graphite-web)
  • flock support for persister and carbonserver
  • cache.max-size and cache.write-strategy can be changed without restart (HUP signal)
  • Google PubSub protocol was added. It receives data from PubSub Subscriptions and can decode protobuf, plain, or pickle messages.
    • The default format is plain. Specify protobuf or pickle by adding an attribute named 'content-type' to the PubSub messsages:
      • application/protobuf
      • application/python-pickle
    • Sample configuration:
[receiver.pubsub]
protocol = "pubsub"
project = "project-name"
subscription = "subscription-name"
# receiver_go_routines = 4
# receiver_max_messages = 1000
# receiver_max_bytes = 500000000 # default 500MB
version 0.11.0
  • GRPC api for query cache was added
  • Added support for an unlimited number of receivers
  • Protobuf protocol was added. Sample configuration:
[receiver.protobuf]
protocol = "protobuf"
listen = ":2005"
  • HTTP protocol was added. It receives data from POST requests body. Data can be encoded in plain, pickle (Content-Type: application/python-pickle) and protobuf (Content-Type: application/protobuf) formats. Sample configuration:
[receiver.http]
protocol = "http"
listen = ":2006"
  • Kafka protocol was added. It receives data from Kafka and can decode protobuf, plain or pickle messages. You need manually specify message format in the config file. Sample configuration:
[receiver.kafka]
protocol = "kafka"
parse-protocol = "protobuf" # can be also "plain" or "pickle"
brokers = [ "localhost:9092" ]
topic = "graphite"
partition = 0
state-file = "/var/lib/graphite/kafka.state"
initial-offset = "-30m" # In case of absent or damaged state file fetch last 30 mins of messages
version 0.10.0

Breaking changes:

  • common: logfile and log-level in common config section are deprecated
  • changed config defaults:
    • user changed to carbon
    • whisper directory changed to /var/lib/graphite/whisper/
    • schemas config changed to /etc/go-carbon/storage-schemas.conf
  • rpm:
    • binary moved to /usr/bin/go-carbon
    • configs moved to /etc/go-carbon/
  • deb:
    • binary moved to /usr/bin/go-carbon

Other changes:

  • common: Requires Go 1.8 or newer
  • common: Logging refactored. Format changed to structured JSON. Added support of multiple logging handlers with separate output, level and encoding

  • carbonserver: [feature] support /metrics/details handler, that returns information about metrics (require enabled trigram-index)
  • carbonserver: [feature] Add config option to disable trigram index (before that to disable index you should set scan-interval to 0)
  • carbonserver: [fix] fix #146 (metrics_known was broken if metrics were not sent as counters)
