Name

Metric Name

Description

 

 

 

Data Region Virtual

PROC_REGION_VIRT_DATA

Size (in KBs unless otherwise indicated) of the total virtual

Memory

 

memory occupied by data regions of this process. This value

 

 

is not affected by the reference count since all data regions

 

 

are private.

Data Region Resident

PROC_REGION_RES_DATA

Size (in KBs unless otherwise indicated) of the total resident

Memory

 

memory occupied by data regions of this process. This value

 

 

is not affected by the reference count since all data regions

 

 

are private.

Process Kernel

PROC_THREAD_COUNT

Total number of kernel threads for the current process.

Threads

 

 

Process Open Files

PROC_FILE_OPEN

Number of files the current process has remaining open as

 

 

of the end of the interval.

Process Physical IO

PROC_IO_BYTE_RATE

Number of physical IO KBs per second used by this process

Rate

 

or kernel thread, either directly or indirectly, during the

 

 

interval.

Process Physical Disk

PROC_DISK_PHYS_IO_RATE

Average number of physical disk IOs per second made by

IO Rate

 

the process or kernel thread during the interval.

Glance System Call Data

The Glance System Call display provides a graph of data obtained from the PROC_SYSCALL loop in Glance Plus. For additional details, see the HP GlancePlus for HP-UX Dictionary of Operating System Performance Metrics. At each sampling interval, all system calls that exceed a predefined rate are written to the data file. Six items are recorded for each system call. They are shown below, with the GlancePlus items they correspond to in parentheses:

•Count for this system call since the last sample (PROCSYSCALL_CALL_COUNT)•Cumulative count for this system call (PROCSYSCALL_CALL_COUNT_CUM)•Rate for this system call (PROCSYSCALL_CALL_RATE)•Cumulative rate for this system call (PROCSYSCALL_CALL_RATE_CUM)•Time spent in this system call (PROCSYSCALL_TOTAL_TIME)•Cumulative time spent in this system call (PROCSYSCALL_TOTAL_TIME_CUM)

These metrics provide information about the system call behavior of the selected process. You can use the display to look for high system call activity.
