View real-time sync nodes in the node list

The node list displays real-time sync nodes that are run by the scheduling system. You can manage these nodes and perform O&M operations on these nodes. For example, you can view the basic information, properties, and operational information of a real-time sync node. You can also start or undeploy a real-time sync node. 11
Section Description
1 In this section, you can specify filter conditions to search for real-time sync nodes.

You can specify the following filter conditions to search for nodes: Task node name, Status, Responsible Person, Source Type, Source Name, Operated By, Destination Type, Destination Name, and Data Integration Resource Group.

Note When you search for nodes by node name, the search result is affected by other filter conditions that you specified. Only the nodes that meet all filter conditions are displayed.
2 In this section, you can view the following information about the real-time sync node that you want to query:
  • ID: the ID of the node.
  • Task name: the name of the node. You can click the node name to go to the details page of the node.
  • Status: the status of the node. The node can be in one of the following states: Running, Not Running, Waiting for Resources, Exception, and Stop or Stopping.
  • Description: the description of the node.
  • Business delay: the period of time between the current time and the offset from which incremental data starts to be synchronized.
  • Current synchronization site: the offset at which incremental data is being synchronized.
  • Recent operation time: the time when an operation was performed on this node.
  • Recent operator: the user who last performed an operation on the node.
  • Source Type: the type of the source.
  • Source data source: the name of the source.
  • Destination Type: the type of the destination.
  • Destination: the name of the destination.
  • Responsible Person: the owner of the workspace to which the node belongs.
  • Current Start Site: the offset from which incremental data starts to be synchronized.
  • Data Read Speed (Bytes per Second): the speed at which the data is read.
  • Recording Speed: the speed at which the read data is written to logs.
  • Data Integration Resource Group: the resource group that is used to run the node.
3 In this section, you can perform the following operations on multiple nodes at a time:
  • Start: Start the nodes.
  • Stop: Stop the nodes that are running.
  • Undeploy: Undeploy the nodes that are not running, abnormal, or stopped.
  • Configure Alert Rule: Configure alert rules for the nodes.
  • Operation alarm: Delete, enable, or disable alert rules and modify alert rules based on metric types.

View the details about a real-time sync node

Find the real-time sync node that you want to query and click the node name to go to the details panel of the node. In the details panel of the node, you can view the details about the node on the Operation Information, Log, Basic Properties, Task configuration, Failover records, and DDL records tabs. 333

Perform operations on a real-time sync node

  • Start a real-time sync node
    Find the node that you want to start and click Start in the Operation column. Then, the Start dialog box appears. After you set the parameters in the dialog box, click Confirm. Then, the system starts to run the node. Start dialog box

    If you select Reset site, you must set the Start time point and Time zone parameters.

  • Stop a real-time sync node

    Find the real-time sync node that you want to stop and click Stop in the Operation column. Then, click Stop in the message that appears to stop the node.

  • Undeploy a real-time sync node

    Find the node that you want to undeploy and click Undeploy in the Operation column. Then, click Undeploy in the message that appears to undeploy the node.

  • View the alert settings of a real-time sync node
    • Find the node whose alert rule settings you want to view and click Alarm settings in the Operation column. On this Alarm event tab, you can view alert events of the node and filter alert events by setting the Occurrence time, Alarm Level, and Rules parameters.
    • Click the Alarm rules tab. On this tab, you can view all the alert rules that are created for the node. You can view the metric type and status of an alert rule. You can also modify, disable, delete or test an alert rule in the Operation column.
