WDR Information

**Table 1** Contents of WDR
Item	Description
Database Stat	Database performance statistics: transactions, read and write operations, row activities, write conflicts, and deadlocks. Database range report. This report can be queried in both cluster and node modes.
PDB Info	Displays PDB information in the current database. The information includes the PDB logical ID, PDB name, PDB enabling status, PDB resource pool ID, and PDB access permission.
Load Profile	Database performance statistics: CPU time, DB time, logical or physical read, I/O performance, login and logout, load strength, and load performance. Database range report. This report can be queried in both cluster and node modes. This report can be viewed only in non-database-level WDR reports.
Instance Efficiency Percentages	Database-level or node-level cache hit ratio. Database/Node-wide report, which can be viewed in cluster or node mode. This report can be viewed only in non-database-level WDR reports.
Top 10 Events by Total Wait Time	Most time-consuming event. Node-wide report, which can be viewed in node mode. This report can be viewed only in non-database-level WDR reports.
Wait Classes by Total Wait Time	Category of the wait time that is most time-consuming. Node-wide report, which can be viewed in node mode. This report can be viewed only in non-database-level WDR reports.
Host CPU	CPU usage of the host. Node-wide report, which can be viewed in node mode. This report can be viewed only in non-database-level WDR reports.
IO Profile	I/O usage in the database or node dimension. Database/Node-wide report, which can be viewed in cluster or node mode. This report can be viewed only in non-database-level WDR reports.
Memory Statistics	Kernel memory usage distribution. Node-wide report, which can be viewed in node mode. This report can be viewed only in non-database-level WDR reports.
Time Model	Time model data generated by running SQL statements on a node range. Node-wide report, which can be viewed in node mode. This report can be viewed only in non-database-level WDR reports.
SQL Statistics	SQL statement performance statistics are displayed in the following dimensions: total time, average time, lock waiting time, CPU duration, number of returned rows, number of scanned rows, number of execution times, logical read, and physical read. Database/Node-wide report, which can be viewed in cluster or node mode.
Wait Events	Statistics on wait events at the node level. Node-wide report, which can be viewed in node mode. This report can be viewed only in non-database-level WDR reports. For details, see "Waiting state list", "List of wait events corresponding to lightweight locks", "List of wait events corresponding to I/Os", and "List of wait events corresponding to transaction locks" in "System Catalogs and System Views > System Views > Other System Views > PG_THREAD_WAIT_STATUS" in the Developer Guide.
Cache IO Stats	I/O statistics on user tables and indexes. Database/Node-wide report, which can be viewed in cluster or node mode. This report can be viewed only in non-database-level WDR reports.
Utility status	Status information about the replication slot and background checkpoint. Node-wide report, which can be viewed in node mode. This report can be viewed only in non-database-level WDR reports.
Object stats	Performance statistics in the index and table dimensions. Database/Node-wide report, which can be viewed in cluster or node mode.
Configuration settings	Node configuration. Node-wide report, which can be viewed in node mode. This report can be viewed only in non-database-level WDR reports.
SQL Detail	SQL statement text details. Database/Node-wide report, which can be viewed in cluster or node mode.
