Metric
Description
Avrg-Mem-QLen
Average number current processes waiting for page fault to be serviced.
Avrg-Process-Load
Average CPU-Load value of an active process on the current processor.
Busy-Memory
Percentage of Memory on the CPU that is not available for use by applications.
Cache-Hits.nb/s
Number of times per second that required block was found in cache during an I/O
operation.
Comp-Trap.nb/s
Number of times per second compatibility trap occurred on the processor.
Cpu-Busy.% For D, G, and H series. CPU-busy.% is the percentage of time for which the CPU was
busy during the sample time. It also represents the utilization of the CPU.
For J-series, Cpu-busy.% represents the utilization of the CPU, which is the ratio of current-
utilization to the maximum utilization of the CPU. In other words, it denotes the portion of
the maximum capacity of the CPU used. This value should never be compared with busy-
time of other entities.
Cpu-busy.% is always smaller than 100%. For entity comparisons and real CPU activity,
use the Cpu-busy-time.% metric.
Cpu-busy-time.%
For J-series (NSMA) only. This represents the busy-time of the CPU defined as the busy-
time sum of all the Instruction Processing Unit (IPU), logical processor or Core--
Cpu-busy-time.% = SUM(ipu<n>-busy-time.%).
Cpu-busy-time.% is always smaller than 100%* number-of-ipu
NOTE: Cpu-busy.% = cpu-busy-time.% / number-of-ipu
ipu<nn>-busy-time.%
For J-series (NSMA) only. This represents the percentage of time that the IPU was busy
during the sample time. For the First J-series systems, up to 16 ipu<nn>-busy-time metrics
can be defined from 0 to 15. First J-series systems used dual core Itanium processor and
have only 2 IPUs per processor.
ipu<nn>-dispatches
For J-series. Represents the number of dispatches for this IPU.
ipu<nn>-Qtime.%
For J-series. Represents the percentage of time that processes spend on the ready list.
CPU-Overhead.%
Percentage of time that the CPU spent creating and deleting processes.
CPU-QLen-Max.nb
The maximum number of processes that are ready to execute
CPU-Qtime.%
Percentage of time that processes spent on the ready list.
CPU-Queue-Len.nb
The number of current processes that are ready to execute (snapshot).
CPU-Wait.ms
Average time a process waited to access the CPU during the sample time. This metric is
equal to the total CPU wait divided by the number of existing processes on the CPU while
the metric Activ-Prs-Wait.ms is equal to the total CPU wait divided by the number of
processes that have effectively CPU time
Curlocked-Memory.%
Percentage of CPU memory currently locked by the system or user-processes.
Disc-Cpu-Busy.%
Percentage of CPU-Busy used by DISC PROCESSES on the CPU.
Disc-IOnb/s
Number of Disc I/Os per second for this processor (CPU).
Free-Memory.%
Percentage of Memory on the CPU that is available for use by applications.
High-Pcb-Curr.nb
Number of current Processes with High-Pin on the CPU (snapshot).
High-Pcb-Free.nb
Number of free Process Control Blocks in High-Pin on the CPU (snapshot).
Intr-Busy.%
Percentage of time that the CPU spent executing interrupts handlers.
Line-Cpu-Busy.%
Percentage of CPU-Busy used by LINE HANDLERS on the CPU.
Low-Pcb-Curr.nb
Number of current Processes with Low-Pin on the CPU (snapshot).
Low-Pcb-Free.nb
Number of free Process Control Blocks in Low-Pin on the CPU (snapshot).
Mem-Queue-Len.nb
Number of current processes waiting for page fault to be serviced (snapshot).
Memory-Swaps.nb/s
Number of Memory swaps per second during the sample time on the CPU
Memory-Wait.us
Average amount of time that any process had to wait to access memory.
NETline-Cpu-Busy.%
Percentage of CPU-Busy used by NETLINE HANDLERS on the CPU.
Page-Fault.nb/s
The number of page-fault interrupts during the collect time.
