Package: carbonate3
carbonate3Carbonate for Python 3.6Based on carbonate project for Python 2 (https://github.com/graphite-project/carbonate)Graphite clusters are pretty cool. Here are some primitive tools to help you manage your graphite clusters.All of the tools support two common arguments; the path to a config file, and the name of the cluster. Using these tools alongside a config file that describes your graphite clusters you can build up scripts to manage your metrics. Some of the tools could easily be replaced with one-liners in shell, but exist here for convenience and readability. The goal is to provide fast, predictable utilities that can easily be composed into more advanced tooling.InstallCarbonate is available from Python official third party repository(aka PyPi) and as such can be installed via regular Python package managers.
Note that you might have to install a python package manager (e.g. apt-get install python-setuptools on a ubuntu host)pip install carbonate3The ConfigCarbonate expects a configuration file that defines the clusters in your environment. The default config file is located at/opt/graphite/conf/carbonate.confor can be provided on the command line. The default cluster is named 'main'. Both defaults can be overridden by setting in the environmentCARBONATE_CONFIGandCARBONATE_CLUSTERrespectively.[main]

REPLICATION_FACTOR = 2
SSH_USER = carbonate
HASHING_TYPE = fnv1a_chYou should take care to match the list of destination IPs or hostnames to the nodes in your cluster (i.e. it should match with routing configuretion of your carbon relay). Order is important because of how the consistent hash ring is created.The replication factor should match the replication factor for the cluster.Also, you can choose to provide a SSH user that will be used when carbonate requires connecting to another node in the cluster to perform an operation. If this is not provided, then the current user executing the command will be chosen.Finally, you can provide HASHING_TYPE of your cluster. Default iscarbon_ch, alsofnv1a_chis supported. Please note that for usingfnv1a_chhashing you needcarbon1.0.2 or newer installed (or you need to usecarbon-c-relayrelay instead).The Toolscarbon-hostsusage: carbon-hosts [-h] [-c CONFIG_FILE] [-C CLUSTER]
