Version: 2.3.11

RESTful API V2

SeaTunnel has a monitoring API that can be used to query status and statistics of running jobs, as well as recent completed jobs. The monitoring API is a RESTful API that accepts HTTP requests and responds with JSON data.

Overview

The v2 version of the api uses jetty support. It is the same as the interface specification of v1 version , you can specify the port and context-path by modifying the configuration items in seatunnel.yaml, you can configure enable-dynamic-port to enable dynamic ports (the default port is accumulated starting from port), and the default is closed, If enable-dynamic-port is true, We will use the unused port in the range within the range of port and port + port-range, default range is 100

seatunnel:
  engine:
    http:
      enable-http: true
      port: 8080
      enable-dynamic-port: true
      port-range: 100

Context-path can also be configured as follows:

seatunnel:
  engine:
    http:
      enable-http: true
      port: 8080
      context-path: /seatunnel

API reference

Returns an overview over the Zeta engine cluster.

GET /overview?tag1=value1&tag2=value2 (Returns an overview over the Zeta engine cluster.)

Parameters

name type data type description
tag_name optional string the tags filter, you can add tag filter to get those matched worker count, and slot on those workers

name	type	data type	description
tag_name	optional	string	the tags filter, you can add tag filter to get those matched worker count, and slot on those workers

Responses

{
    "projectVersion":"2.3.10-SNAPSHOT",
    "gitCommitAbbrev":"DeadD0d0",
    "totalSlot":"0",
    "unassignedSlot":"0",
    "works":"1",
    "runningJobs":"0",
    "finishedJobs":"0",
    "failedJobs":"0",
    "cancelledJobs":"0"
}

Notes:

If you use dynamic-slot, the totalSlot and unassignedSlot always be 0. when you set it to fix slot number, it will return the correct total and unassigned slot number
If the url has tag filter, the works, totalSlot and unassignedSlot will return the result on the matched worker. but the job related metric will always return the cluster level information.

Returns An Overview And State Of All Jobs

GET /running-jobs (Returns an overview over all jobs and their current state.)

    "logName": "job-899470314109468673.log"
  }
]

Supported formats are json and html, with html as the default.

Examples

Retrieve logs for jobId 733584788375666689 across all nodes: http://localhost:8080/logs/733584788375666689 Retrieve the list of logs from all nodes: http://localhost:8080/logs Retrieve the list of logs in JSON format: http://localhost:8080/logs?format=json Retrieve the content of a specific log file: http://localhost:8080/logs/job-898380162133917698.log

Get Log Content from a Single Node

GET /log (Returns a list of logs.)

Response

Returns a list of logs from the requested node.

Examples

To get a list of logs from the current node: http://localhost:5801/log To get the content of a log file: http://localhost:5801/log/job-898380162133917698.log

Get Node Metrics

GET /metricsGET /openmetrics

To get the metrics, you need to open Telemetry first, or you will get an empty response.

More information about Telemetry can be found in the Telemetry documentation.
