Svmon-P commands in Aix

Svmon-p-t 3-I 5. This command outputs the first three processes that consume the most memory every five seconds.

(Some output is omitted)

Description (for clarity, both Chinese and English comparisons are provided)

Process report

The process report is printed when the-P Flag is specified. The column headings in a process report are:
PID
Indicates the process ID.
Command
Indicates the command the process is running.
Inuse
Indicates the total number of pages in real memory in segments that are used by the process.
Pin
Indicates the total number of pages pinned in segments that are used by the process.
Pgsp
Indicates the total number of pages reserved or used on paging space by segments that are used by the process.
Virtual
Indicates the total number of pages allocated in the process virtual space.
64-bit
Indicates if the process is a 64 bit process (y) or a 32 bit process (n ).
Mthrd
Indicates if the process is multi-threaded (y) or not (n ).
16 MB
Indicates the 16 MB Page Status of the process. "M" stands for mandatory, "Y" means that the process uses or has used
16 MB page segments and "N" means that the process does not use 16 MB pages.

If the process uses pages of a size other than the base 4kb page size, these statistics are followed by
Distribution between the different page sizes.

After process information is displayed, svmon displays information about all the segments the process uses. Information
About segment are described in the paragraph segment report

If the-Q flag is specified, only processes using segments of the requested size are reported. Note that all of
Segments for these processes are reported. If a list of processes is specified, an error is reported for each process not
Using segments of the requested size.

Process report

Only-PTo print the process report. The column title in the Process report is:

PID

Process identifier.

Command

Indicates the command that the process is running.

Using

Indicates the total number of pages of the real memory in the segment used by the process.

Fixed memory

The total number of fixed memory pages in the segments used by the process.

Paging Space

The total number of pages that the process uses to retain or use in the paging space.

Virtual

Indicates the total number of pages allocated in the virtual space of a process.

64-bit

Indicates whether the process is a 64-bit process (y) or 32-bit process (n ).

Multithreading

Indicates whether the process is multi-threaded (y) or not multi-threaded (n ).

Large page

Indicates the large page status of the process." m "indicates mandatory," Y "indicates that the process uses or has used a large page segment," n "indicates that the process does not use a large page.

if a large page pool is defined, the distribution of different page sizes follows this information.

After the process information is displayed,SvmonDisplays information about all segments used by the process. SectionSegment reportDescribes the segment information.

If-QFlag, then only the reports marked as large page process (Lpage. Be sure to report all the segments in these processes. If a process column is specified, an error is reported to every process that is not marked as a large page.

Segment report

Only-STo print the report. The column title in the Section report is:

Vsid

Indicates the virtual segment identifier. Indicates the unique segment in the Virtual Memory Manager.

ESID

A valid segment identifier. The ESID is valid only when the segment belongs to the address space of the process. When provided, it indicates how the process uses segments. If the vsid segment is mapped by several processes but has different ESID values, this field contains "-". If that is the case, apply
-PTo obtain the exact ESID value. Because the segments used to manage open files or multi-threaded structures are not part of the user address space of the process, "-" is also displayed for these segments.

Type

Indicates the type of the segment:

• PersistentPersistent segments
• WorkWork segment
• CustomerCustomer segment
• IngIndicates the ing segment.
• Real ingIndicates the real memory ing segment.

Description

The text description of the segment. The column content depends on the type and purpose of the segment.
