A Wishbone encode module to flatten a dict structure of arbitrary depth into individual metric events.

__ __ __ .--.--.--|__.-----| |--| |--.-----.-----.-----. | | | | |__ --| | _ | _ | | -__| |________|__|_____|__|__|_____|_____|__|__|_____| version 2.1.2 Build composable event pipeline servers with minimal effort. ======================= wishbone.encode.flatten ======================= Version: 1.0.0 Flattens a dict structure of arbitrary depth into individual metric events. --------------------------------------------------------------------------- This module takes a <dict> structure and recursively travels it flattening the namespace into a dotted format untill a numeric value is encountered. For each metric a <wishbone.event.Metric> datastructure is created and stored in the @data part of <wishbone.event.Event>. Non-numeric values are ignored. For example: {"server": {"host01": {"memory": {"free": 10, "consumed": 90}}}} Would generate following metrics: server.host01.memory.free server.host01.memory.consumed These metrics are converted to the Wishbone metric data format: http://wishbone.readthedocs.org/en/latest/logs%20and%20metrics.html#format The module is expecting a Python <dict> type. That means you should have already decoded the incoming data using a module like wishbone.decode.json. Parameters: - source(str)("@data") | The event field containing the data to convert. - type(str)("wishbone") | An arbitrary string to assign to the "type" field of the Metric | datastructure. - metric_source(str)("wishbone") | An arbitrary string to assign to the "source" field of the Metric | datastructure. - tags(set)() | An arbitrary set of tags assign to the "tags" field of the Metric | datastructure. Queues: - inbox: Incoming events. - outbox: Outgoing events with @data containing the wishbone.event.Metric data.
