Computation details for AIX metrics
This topic provides computation information for AIX metrics and indicators. For more information, refer to the following sections:
AIX Host - CPU Pressure Index
An index between 0 and 100. Higher the value, higher the pressure. This metric is calculated for vSphere hosts and clusters.
The following points about CPI should be noted:
- CPI Value: CPU Pressure Index will have a value in the range of 0 – 100. Higher the number, higher the pressure.
- Minimum value: Minimum value of CPU pressure = CPU Utilization
- Penalty Points: There are Penalty Points for High CPU Queue Length scenarios and they are elaborated in the table that follows.
The following table elaborates computation and other important details for AIX Host - CPU Pressure Index (CPI):
AIX Host - Memory Pressure Index
An index between 0 and 100. Higher the value, higher the pressure.
The following points about MPI should be noted:
- MPI Value: MPI will have a value in the range of 0 – 100. Higher the number, higher the pressure.
- Minimum value: Minimum value of memory pressure = Real Memory Utilization
- Penalty points: There are penalty points for Paging and Virtual Memory Used scenarios, and they are discussed in detail in the table that follows.
