rest-api


REST API

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 REST-ful 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 rest 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
