Use this Knowledge Script to monitor the demand placed on a database instance from all sources. This demand is determined by tracking the number of database calls per second from all applications and processes accessing the database instance. The database calls that are tracked include Parse, Execute, and Fetch statements. These calls are sometimes described as user calls. When the call rate (and thus the workload demand on the server) exceeds the threshold you set, the job raises an event.
The account you use to run this script must have SELECT permissions for the following tables:
V_$SYSSTAT
V_$VERSION
Oracle Database folders. When you drop a script on an Oracle Database folder, a job executes on that database and monitors only that database.
The default interval for this script is Every 10 minutes.
Set the following parameters as needed:

Description |
How to Set It |
|---|---|
|
Oracle Username |
Enter the username that this script needs to access the target databases. If you run this script on more than one database, configure each database with the same username. To use SYSDBA authentication, leave this parameter blank. The default is blank. |
|
Collect data for call rate? |
Select Yes to collect data for charts and reports. When you enable data collection, the Knowledge Script returns the total user calls per second for all work sources. The default is unselected. |
|
Raise event if threshold is exceeded? |
Select Yes to raise an event if the maximum number of calls per second exceeds the threshold. The default is Yes. |
|
Threshold - Maximum call rate |
Enter a threshold for the maximum number of calls per second allowed before the job raises an event. The default is 100. |
|
Severity |
Set the event severity level, from 1 to 40, to indicate the importance of the event. The default is 5 (red event indicator). |
|
Event severity for internal failure |
Set the event severity level, from 1 to 40, to indicate the importance of the event. The default is 5 (red event indicator). |
