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: false
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

}
Notes:
- If you use
dynamic-slot
, thetotalSlot
andunassignedSlot
always 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
,totalSlot
andunassignedSlot
will return the result on the matched worker. but the job related metric will always return the cluster level information.
