Instance Diagnose

The instance diagnostic information of an instance is displayed in the Upstream Nodes, Resources, and Execution steps.
  • Upstream Nodes
    The Upstream Nodes step on the Instance Diagnose tab displays the running status of ancestor nodes of the current node. This tab helps you find the ancestor node that blocks the running of the current node. Upstream Nodes
  • Resources
    The Resources step on the Instance Diagnose tab displays the resource usage. Based on the information on this tab, you can arrange the scheduled time of the current node to avoid peak hours. Resources
  • Execution
    If the current node fails to run, the Execution step provides you with intelligent diagnostic suggestions based on log information. You can also click Instance List to conduct further analysis. Execution
    Notice The Instance List tab is available only for MaxCompute nodes.

Impact baseline

In the top navigation bar, click Impact baseline to view the baseline of the current node.

Historical instance

In the top navigation bar, click Historical instance to view the information about the last 15 instances of the current node. The information includes Running time, Start run time, Time consumption of waiting for scheduling resources, and Historical instance. Historical instance
