        [![Build Status](https://travis-ci.org/jssjr/carbonate.png)](https://travis-ci.org/jssjr/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.
        
        ## Install
        [Carbonate is available from Python official third party repository](https://pypi.python.org/pypi/carbonate/0.2.1) (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 carbonate
        ```
        ## The Config
        
        Carbonate expects a configuration file that defines the clusters in your environment. The default config file is located at `/etc/carbonate.conf` or can be provided on the command line. The default cluster is named 'main'.
        
        ```
        [main]
        DESTINATIONS = 192.168.9.13:2004:carbon01, 192.168.9.15:2004:carbon02, 192.168.6.20:2004:carbon03
        REPLICATION_FACTOR = 2
        SSH_USER = carbon
        ```
        
        You should take care to match the list of destination IPs or hostnames to the nodes in your cluster. Though its worth noting that the ports and labels are currently not used by carbonate. Order is important because of how the consistent hash ring is created.
        
        The replication factor should match the replication factor for the cluster.
        
        Finally, 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.

        These tools should be considered beta quality right now. Tests exist for most functionality, but there is still significant work to be done to make them bullet-proof. However, instead of sitting on this code, I'd rather release it and allow others to provide input and help guide the development. So, expect a few bugs and please help me fix them!
