RESTful API V1
It is recommended to use the v2 version of the Rest API. The v1 version is deprecated and will be removed in the future.
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 monitoring API is backed by a web server that runs as part of the node, each node member can provide RESTful api capability. By default, this server listens at port 5801, which can be configured in hazelcast.yaml like :
network:
rest-api:
enabled: true
endpoint-groups:
CLUSTER_WRITE:
enabled: true
DATA:
enabled: true
join:
tcp-ip:
enabled: true
member-list:
- localhost
port:
auto-increment: true
port-count: 100
port: 5801
API reference
Returns an overview over the Zeta engine cluster.
GET /hazelcast/rest/maps/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
Responses
{
"projectVersion":"2.3.5-SNAPSHOT",

"totalSlot":"0",
"unassignedSlot":"0",
"works":"1",
"runningJobs":"0",
"finishedJobs":"0",
"failedJobs":"0",
"cancelledJobs":"0"
}
Notes:
- If you use
dynamic-slot, thetotalSlotandunassignedSlotalways be0. 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,totalSlotandunassignedSlotwill return the result on the matched worker. but the job related metric will always return the cluster level information.
Returns thread dump information for the current node.
GET /hazelcast/rest/maps/thread-dump (Returns thread dump information for the current node.)
Returns An Overview And State Of All Jobs
GET /hazelcast/rest/maps/running-jobs (Returns an overview over all jobs and their current state.)

Get All Node Log Content
GET /hazelcast/rest/maps/logs/:jobId (Returns a list of logs.)
Request Parameters
Parameters (Add in the params field of the request body)
Parameter Name Required Type Description jobId optional string job id
When jobId is empty, it returns log information for all nodes; otherwise, it returns the log list of the specified jobId across all nodes.
Response
Returns a list of logs and content from the requested nodes.
Get All Log Files List
If you'd like to view the log list first, you can use a GET request to retrieve the log list:
http://localhost:5801/hazelcast/rest/maps/logs?format=json
[
{
"node": "localhost:5801",
"logLink": "http://localhost:5801/hazelcast/rest/maps/logs/job-899485770241277953.log",
"logName": "job-899485770241277953.log"
},
{
"node": "localhost:5801",
"logLink": "http://localhost:5801/hazelcast/rest/maps/logs/job-899470314109468673.log",
"logName": "job-899470314109468673.log"
}
]
The supported formats are json and html, with html as the default.
