IBM AIX Event Tests

The Oracle Enterprise Manager Advanced Event Tests for IBM AIX are divided into a series of classes or groupings that enable you to find the event test you want to register.

The class names and the events that you can register within the classes are listed as follows:

• CPU Utilization Class: includes the percentage of time the CPU was idle, in a wait state, in system mode, and in user mode (See Table 5-1)

• File System Class: includes available space and used space (See Table 5-2)

• I/O Class: includes read and write operations (See Table 5-3)

• Memory/Swap Class: includes free memory, available swap, and swap queue (See Table 5-4)

• Network Class: includes packet statistics, incoming and outgoing errors, and collisions on the network interface (See Table 5-5)

• Process Class: includes process ID, parent process ID, priority of the process, and size of the process (See Table 5-6)

• System Class: includes operations for page ins, page outs, pages paged in, and pages paged out (See Table 5-7)
