- 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.
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.
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.Notice The Instance List tab is available only for MaxCompute nodes.
In the top navigation bar, click Impact baseline to view the baseline of the current node.
