JP1 Version 12 JP1/Performance Management - Remote Monitor for Virtual Machine Description, User's Guide and Reference


Format of record explanations

This chapter lists in alphabetical order the records used in PFM - RM for Virtual Machine. The explanation of each record consists of the following items.

Organization of this page

Function

Provides an overview of the performance data stored in each record, and notes related to it.

Default values and values that can be changed

This item shows the default values of the performance data collection conditions that are set in each record and the values that can be changed by the user, in table format. The table below shows the items that are described as default values, the values that can be changed, and their meanings. For details about each item shown in this table, see the chapter that explains management of operation monitoring data in the JP1/Performance Management User's Guide.

Table 5‒1: Default values and values that can be changed

Item

Meaning

Changeability

Collection interval

Performance data collection interval (seconds)

Y: Can be changed.

N: Cannot be changed.

Collection Offset#1

Offset for starting performance data collection (seconds). For details about offsets, see the chapter that explains management of operation monitoring data in the JP1/Performance Management User's Guide.

For details about the performance data collection start time, see the chapter that explains Performance Management functions in the JP1/Performance Management Planning and Configuration Guide.

Log

Whether to record the collected performance data in the Store database

Yes: Records the performance data. However, performance data will not be recorded if Collection Interval=0.

No: Does not record the performance data.

LOGIF

Condition for determining whether to record the collected performance data in the Store database

Over 10 Sec Collection Time#2

Whether a certain system configuration can cause record collection to take 10 seconds or longer.

Yes: Record collection might take 10 seconds or longer.

No: Record collection does not take 10 seconds.

#1

A value between 0 and 32,767 seconds (within the value specified in Collection Interval) can be specified. When multiple data items are being collected, the system load will increase if they are all collected at the same time. Therefore, a collection offset is used to distribute the collection load. Note that the data collection recording time is the same as that specified in Collection Interval regardless of the value specified in Collection Offset. When you change the Collection Offset value, specify a value by taking the collection load into consideration.

#2

This property is displayed if the collection of historical data is prioritized over the display processing of real-time reports. For details, see the chapter on troubleshooting in the JP1/Performance Management User's Guide.

ODBC key field

These fields display the primary keys that are necessary to use the data retrieved from records stored in the Store database on PFM - Manager. Some ODBC key fields are common to all records, while others are unique to each record. ODBC key fields unique to individual records are listed under this heading in each record description. Only multi-instance records have unique ODBC key fields.

For the ODBC key fields common to all records, see List of ODBC key fields in this chapter.

Lifetime

Lifetime indicates a period during which the integrity of the performance data collected in each record is guaranteed. For details about lifetime, see the chapter that explains Performance Management functions in the JP1/Performance Management Planning and Configuration Guide.

Record size

Record size indicates the size of the performance data that is stored in each record during a single collection operation.

Fields

The fields of each record are listed in a table. The various items in the table are explained below.
