Manage real-time computing nodes-DataWorks(DataWorks)-阿里云帮助中心

Limitations

DataWorks currently supports O&M only for tasks submitted from EMR Spark Streaming and Flink SQL Streaming nodes.

Go to the real-time computing nodes page

Log on to the DataWorks console. In the target region, click Data Development and O&M > Operation Center in the left-side navigation pane. Select a workspace from the drop-down list and click Go to Operation Center.
In the left-side navigation pane, click Real-time Task O&M > Real-time Computing Node to go to the Real-time Computing Nodes page.

List of real-time computing nodes

The Real-time Computing Nodes page in Operation Center displays a list of real-time compute nodes in the production environment. On this page, you can view basic information about the nodes, perform O&M operations such as Start, Terminate, and Undeploy, and configure alerts for node failures.

The page is divided into the following areas from top to bottom: Area ① is the filter bar at the top, containing a search box for node ID or name, along with dropdown filters for status, cluster type, cluster name, node type, and owner. Area ② is the main task list table, displaying basic information and running status for each node. Area ③ is the Actions column in the table, providing operation entries such as Start, Terminate, Undeploy, and Set Monitor. Area ④ is the bulk actions bar at the bottom, allowing you to select multiple nodes and perform operations in bulk. The following table describes each area in detail.

Area	Description
1	In this area, you can filter real-time compute nodes by criteria such as Node ID, Node Name, Status, Cluster Type, Cluster Name, Task type, and Owner. Note Search results for Node ID or Node Name are affected by other filter conditions. The query returns only nodes that meet all filter criteria. Searching by Node Name supports fuzzy match. When you enter a keyword, the search returns all real-time compute nodes with names containing that keyword.
2	In this area, you can view the basic information and running status of the target nodes. Node Name: The name of the node. Click the node name to go to the details page for the target node. Node ID: The ID of the node. Running status: The running status of the node. The possible states include Not Running, Generating, Waiting for resources, Starting, Running, Stopped, Failed, Restarting, and Undeploying. Start running: The time when the node started running. End Running: The time when the node stopped running. Run when Long: The node's total runtime, in seconds. Task type: The type of the node. Note DataWorks currently supports O&M only for tasks submitted from EMR Spark Streaming and Flink SQL Streaming nodes. Cluster Type: The type of cluster that the node uses. DataWorks currently supports O&M only for real-time compute nodes that run on E-MapReduce and Flink clusters. Cluster Name: The name of the cluster where the node runs. Deployed At: The time the node was deployed, in yyyy-MM-dd HH:mm:ss format. Owner: The person in charge of the node's workspace. Note You can sort nodes in ascending/descending order by Start running, End Running, or Run when Long.
3	In this area, you can perform the following operations on a node. Start: Starts a real-time compute node that is not running. Terminate: Terminates a running real-time compute node. Undeploy: Undeploys a real-time compute node. Monitoring Setting: Configures monitoring for a node's running status. If the node fails, DataWorks sends an alert to the specified alert contacts via SMS, Email, Telephone, DingTalk Chatbot, or Webhook. To configure an alert contact's Email and Telephone, see Set the mobile phone number and email address for an alert contact. To configure a DingTalk chatbot and get its webhook URL, see Use case: Send alert messages to a DingTalk group.
4	In this area, you can select multiple nodes to perform bulk operations: Start, Terminate, Undeploy, or configure Monitoring Setting.

Real-time compute node details

In the node list, click a node name to open its details page. On the details page, you can view the node's Details, Runtime Log, Operation Log, and Code. This allows you to quickly find operation records and troubleshoot errors.

After you select the Details tab, the page displays the following two sections:

Basic Information: includes Name, Node ID, Task type, Owner, Workspace, Latest Version, Deployed At, Resource Group, Running CU, Region, Cluster Type, and Cluster Name.
Running Information: includes Instance ID, Status, Running Version, Start running, Start Waiting for Resource, Resource Waiting Duration, End Time, and Run when Long.
