RESTful API V1

warn

推荐使用v2版本的Rest API。 v1 版本已弃用，并将在将来删除。

SeaTunnel有一个用于监控的API，可用于查询运行作业的状态和统计信息，以及最近完成的作业。监控API是RESTful风格的，它接受HTTP请求并使用JSON数据格式进行响应。

概述

监控API是由运行的web服务提供的，它是节点运行的一部分，每个节点成员都可以提供rest API功能。默认情况下，该服务监听端口为5801，该端口可以在hazelcast.yaml中配置，如下所示：

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参考

返回Zeta集群的概览

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

参数

参数名称是否必传参数类型参数描述
tag键值对否字符串一组标签值, 通过该标签值过滤满足条件的节点信息

参数名称	是否必传	参数类型	参数描述
tag键值对	否	字符串	一组标签值, 通过该标签值过滤满足条件的节点信息

响应

{
    "projectVersion":"2.3.5-SNAPSHOT",
    "gitCommitAbbrev":"DeadD0d0",
    "totalSlot":"0",
    "unassignedSlot":"0",
    "works":"1",
    "runningJobs":"0",
    "finishedJobs":"0",
    "failedJobs":"0",
    "cancelledJobs":"0"
}

注意:

当你使用dynamic-slot时, 返回结果中的totalSlot和unassignedSlot将始终为0. 设置为固定的slot值后, 将正确返回集群中总共的slot数量以及未分配的slot数量.
当添加标签过滤后, works, totalSlot, unassignedSlot将返回满足条件的节点的相关指标. 注意runningJobs等job相关指标为集群级别结果, 无法根据标签进行过滤.

返回当前节点的线程堆栈信息。

GET /hazelcast/rest/maps/thread-dump (返回当前节点的线程堆栈信息。)
