Data Bags

This cookbook optionally uses an encrypted data bag to store the graphite password.
If this data bag is not present the cookbook will use node['graphite']['password']
instead. To use the encrypted data bag set node['graphite']['encrypted_data_bag']['name']
with the name of the data bag you wish to use.

Helper Scripts

The following helper scripts are included in the graphite/bin directory:

• whisper-clean-this-node.sh - this script cleans the whisper metrics that belong to other machines in the cluster. Usually used after synchronizing the storage/whisper directory. Uses the whisper-clean.py script internally

Usage

recipe[graphite] should build a stand-alone Graphite installation.

recipe[graphite::carbon_aggregator] builds the aggregation_rules and storage-aggregation config files,
and configures the carbon-aggregator service.
