Last Sample

Eng. Busy %

The percentage busy for this engine.

CPU Busy %

The percentage CPU time all engines spent not idle.

I/O Busy %

The percentage of input/output resources currently being used by the database engine.

Cont. Switches %

The percentage of the total number of context switches for the engine divided by those completed for all engines.

Context Switches rate (c/s)

The count of context switches for the engine occurring per second.

Disk IO Checks rate

The number of times the engine checked for asynchronous disk I/O.

Checks Returning I/O %

The percentage of disk I/O checks with I/O pending.

Async IO Completed

The number of times the engine completed I/O.

Processes Affinitied

The number of processes affined with the engine.

Time Range Period

Total Busy

Max Busy %

The maximum percentage busy for all of the database engines.

Avg I/O Busy %

The average percentage of input/output resources currently being used by all of the database engines.

Avg CPU Busy %

The average percentage CPU time all database engines spent not idle.

Cont. Switches %

The percentage of the total number of context switches for one engine divided by those completed for all engines.
