PERF_QUERY

Provides the name, tree structure, and percentage of the stack information collected on the current node, as shown in Table 1. The MONADMIN permission is required. In the multi-tenancy scenario, global information is returned if this view is accessed in a non-PDB, and an error is reported if this view is accessed in a PDB.

Before using this view to query stack information, you need to execute the gs_perf_start function to collect flame graph data.
