Recording configuration details

Recording configuration details are logged for each recorded file with a time stamp. The details include different tags and each tag has its own specification.

All tags that have prefix AAA represent recording configuration details. These configuration details are recorded initially when the recording begins. The tags that have prefix ZZZZ represent the end of each record in the recording file. This tag also represents the time stamp of that sample.

The recording configuration can have the following fields:

progname

Name of the binary that is executed.

command

Full command name with arguments that are specified during the start of the recording.

version

For the AIX® operating system, the version is TOPAS_NMON.

build

Build level of the AIX operating system. In TOPAS_NMON, this field has the value AIX.

disks_per_line

Number of disks per line that must be recorded by the nmon tool. 150 lines are recorded by default. You can use the -l option to configure this field.

host

Host name of the logical partition (LPAR).

user

User name of the user by whom the recording was initiated.

VIOS

VIOS build level. This field is logged only when the recording is started in a Virtual I/O Server.

AIX

Provides AIX version details in the format version.technology level.service pack.

TL

Technology level of the base operating system.

runname

Name of the nmon recording session that is running. By default, the runname field indicates the host name of the LPAR that has initiated the recording session. You can use the -r option to configure the runname field.

time

Start time of the recording. By default, time is set to the local time. The -G option is used to configure the recording time in Greenwich Meridian Time (GMT).

gmt

Indicates that GMT is enabled for this recording. This field is not displayed if GMT is not enabled. You can use -G option to configure the gmt field.

date

Start date of the recording.

interval

Interval duration of the recording in seconds. This field is the interval between two consecutive recording snapshots. You can use the -s option to enable the interval field.

snapshots

Number of snap shots that must be recorded. You can use the -c option to configure the snapshots field.

hardware

Processor architecture. This field can have one of the following values: POWER, PowerPC, and unknown.

Implementation

Processor on which the LPAR is running. This field can have one of the following values: POWER6, POWER6_COMPAT_MODE, POWER7, POWER7+, POWER7_COMPAT_MODE, POWER8.

Bit

32-bit or 64-bit.

subprocessorMode

Mode of the subprocessor.

cpus

Current number of logical CPUs.

Kernel

Version of the kernel.

HW-Type

The model architecture of this platform.

Bus

The model implementation of this platform.

LPAR

Type of the LPAR, mode of the kernel, and type of the kernel.

Serial Number

System ID number.

MachineType

Machine type and mode number.

LPARNumberName

Partition ID of the LPAR and LPAR name.

NodeName

Name of the system that is determined by using Unix-to-Unix Copy (UUCP) communications network.

timestampsize

Specifies the size of the time stamp parameter in the T<samplenumber> format. The value of this field is in the range 4 - 16. By default, the configured value is 4.

T<samplenumber>

Timestamp Identifier. This field is used to uniquely identify samples that are collected by the nmon tool for a specific time stamp. The corresponding time stamp is mentioned in ZZZZ tab. This field is represented in Tnnnn format. The value of the number parameter is in the range 4 - 16. For nmon analyzer, you can either use 4 or 8 as the value for the identifier. The timestamp field is present for each tag of the nmon recording.

Note: The timestamp field is not represented as AAA, T <sample number>. This field is present in each sample of the recording after the AAA section is completed.
