»Evaluations HTTP API

The /evaluation endpoints are used to query for and interact with evaluations.

»List Evaluations

This endpoint lists all evaluations.

Method	Path	Produces
`GET`	`/v1/evaluations`	`application/json`

The table below shows this endpoint's support for blocking queries and required ACLs.

Blocking Queries	ACL Required
`YES`	`namespace:read-job`

»Parameters

prefix (string: "")- Specifies a string to filter evaluations based on an ID prefix. Because the value is decoded to bytes, the prefix must have an even number of hexadecimal characters (0-9a-f). This is specified as a query string parameter.
next_token (string: "") - This endpoint supports paging. The next_token parameter accepts a string which is the ID field of the next expected evaluation. This value can be obtained from the X-Nomad-NextToken header from the previous response.
per_page (int: 0) - Specifies a maximum number of evaluations to return for this request. If omitted, the response is not paginated. The ID of the last evaluation in the response can be used as the last_token of the next request to fetch additional pages.
job (string: "") - Filter the list of evaluations to a specific job ID.
status (string: "") - Filter the list of evaluations to a specific evaluation status (one of blocked, pending, complete, failed, or canceled).
namespace (string: "default") - Specifies the target namespace. Specifying * will return all evaluations across all authorized namespaces.

»Read Evaluation

This endpoint reads information about a specific evaluation by ID.

Method	Path	Produces
`GET`	`/v1/evaluation/:eval_id`	`application/json`

The table below shows this endpoint's support for blocking queries and required ACLs.

Blocking Queries	ACL Required
`YES`	`namespace:read-job`

»Parameters

:eval_id (string: <required>)- Specifies the UUID of the evaluation. This must be the full UUID, not the short 8-character one. This is specified as part of the path.
