Fact-paths endpoint

The /fact-paths endpoint retrieves the set of all known fact paths for all known nodes, and is intended as a counterpart to the fact-names endpoint, providing increased granularity around structured facts. The endpoint may be useful for building autocompletion in GUIs or for other applications that require a basic top-level view of fact paths.

`/pdb/query/v4/fact-paths`

This will return all fact paths matching the given query.

URL parameters

query: optional. A JSON array containing the query in prefix notation (["<OPERATOR>", "<FIELD>", "<VALUE>"]). See the sections below for the supported operators and fields. For general info about queries, see our guide to query structure.

If a query parameter is not provided, all results will be returned.

Query operators

See the AST query language page.

Query fields

path (path): the path associated with a fact node.
type (string): the type of the value a the fact node.
depth (integer): the depth of the paths returned

Subquery relationships

The following list contains related entities that can be used to constrain the result set using implicit subqueries. For more information consult the documentation for subqueries.

facts: all facts that contain a fact-path.
fact_contents: all factset paths and values using a fact-path.

Response format

Successful responses will be in application/json. Errors will be returned as a non-JSON string.

The result will be a JSON array with one entry per certname. Each entry is of the form:

{
  "path": <fact-node path>
  "type": <fact-node type>
}

Examples

Using curl from localhost:

Get all fact paths that match the regex array query for paths related to partition sda3:

curl -X GET http://localhost:8080/pdb/query/v4/fact-paths \
  --data-urlencode 'query=["~>", "path", ["partitions", "sda3.*", ".*"]]'

[ {
  "path" : [ "partitions", "sda3", "mount" ],
  "type" : "string"
}, {
  "path" : [ "partitions", "sda3", "size" ],
  "type" : "string"
}, {
  "path" : [ "partitions", "sda3", "uuid" ],
  "type" : "string"
} ]

Get all fact paths of integer type:

curl -X GET http://localhost:8080/pdb/query/v4/fact-paths \
  --data-urlencode 'query=["=", "type", "integer"]'

[ {
  "path" : [ "blockdevice_sda_size" ],
  "type" : "integer"
}, {
  "path" : [ "uptime_days" ],
  "type" : "integer"
}, {
  "path" : [ "blockdevice_sdb_size" ],
  "type" : "integer"
}, {
  "path" : [ "uptime_seconds" ],
  "type" : "integer"
}, {
  "path" : [ "uptime_hours" ],
  "type" : "integer"
} ]

Paging

This query endpoint supports paged results via the common PuppetDB paging URL parameters. For more information, please see the documentation on paging.
