This docker provides access to the Carbon/whisper layer of the graphite stack, inline with the one process per docker philosophy.
It is the intent to run this together with the visity/graphiteweb, visity/statsd and grafana dockers.
Make sure to map the whisper volume to the host for persistence of data.
docker run -d -v $PWD/whisper/:/opt/graphite/storage/whisper/ visity/carbon
Default aggregation configuration is used, including 10 second periods for statsd. Override these in any derived dockers by replacing the storage-aggregation.conf and storage-schemas.conf configuration files.
The following two environment variables override the default behavior:
MAX_UPDATES_PER_SECOND: Overrides the max amount of writebacks per second to storage. WHISPER_AUTOFLUSH: Default False. When set to True, carbon will do the buffering, not the kernel.
Example with the environment variables set at non-default values:
docker run -d -v $PWD/whisper/:/opt/graphite/storage/whisper/ -e MAX_UPDATES_PER_SECOND=10 -e WHISPER_AUTOFLUSH=False visity/carbon
