/api/tree/test

For debugging a rule set, the test endpoint can be used to run a TSMeta object through a tree’s rules and determine where in the heirarchy the leaf would appear. Or find out why a timeseries failed to match on a rule set or collided with an existing timeseries. The only method supported is GET and no changes will be made to the actual tree in storage when using this endpoint.

The messages field of the response contains information about what occurred during processing. If the TSUID did not exist or an error occurred, the reason will be found in this field. During processing, each rule that the TSMeta is processed through will generate a message. If a rule matched on the TSMeta successfully or failed, the reason will be recorded.

Requests

The following fields are required for this endpoint.

Name	Data Type	Required	Description	Default	QS	RW	Example
treeId	Integer	Required	The ID of the tree to pass the TSMeta objects through		treeid		1
tsuids	String	Required	A list of one or more TSUIDs to fetch TSMeta for. If requesting testing of more than one TSUID, they should be separted by a comma.		tsuids		000001000001000001,00000200000200002

Response

A successful response will return a list of JSON objects with a number of items including the TSMeta object, messages about the processing steps taken and a resulting branch. There will be one object for each TSUID requested with the TSUID as the object name. If the requested tree did not exist in the system, a 404 will be returned with an error message. If invalid data was supplied a 400 error will be returned.

Fields found in the response include:

Name	Data Type	Description	Example
messages	Array of Strings	A list of messages for each level and rule of the rule set	See Below
meta	Object	The TSMeta object loaded from storage	See Below
branch	Object	The full tree if successfully parsed	See Below
