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.
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.
-
PFM - View name (PFM - Manager name)
-
Indicates the field name (PFM - View name) displayed on PFM - Web Console.
-
Indicates the field name (PFM - Manager name) to be described in an SQL when you want to use the SQL from PFM - Manager to utilize the data of the field stored in the Store database.
In the SQL statement, the field name is described in a format that has the record ID of each record at the beginning. For example, in the case of the VM Count (VM_COUNT) field of the Host Status Detail (PD) record, describe the field name as PD_VM_COUNT.
-
-
Explanation
Explains the performance data that is stored in each field.
You can obtain the performance data of each field in any of the following ways:
-
Obtain the average or a percentage from the most recently collected data and the data collected during the previous interval
-
Obtain performance data only from the most recently collected data
-
Obtain data from other fields
Unless otherwise specified, the value obtained from a data collection interval is used.
In a historical report, the following types of values can be displayed when records of the PI record type are summarized by specifying a value other than minutes as the reporting interval:
-
The average value for the summary interval
-
The last collected value
-
The total value
-
The minimum value
-
The maximum value
Unless otherwise specified, the average value for the summary interval is displayed for the field value.
-
-
Summary rules
Indicates the summary method (rule) used by Remote Monitor Store to summarize data. For details about summary rules, see Summary rules in this chapter.
-
Grouping rules
Grouping rules refers to a method that is used to consolidate the performance information of remote agents that belong to the same instance. For details about grouping rules, see Grouping rules in this chapter.
-
Format
Indicates the data type, such as double, of the value in each field. For details about data types, see List of data types in this chapter.
-
When data is collected as a cumulative value, a delta value is used to display the data as the changed amount. For details about delta values, see Field values in this chapter.
-
When not collected
Indicates the value that is stored in the field when performance data collection failed.
-
No: Indicates the case in which no data for the entire record can be collected when performance data collection fails.
-
--: Indicates a field in which data can always be collected.
-
-
Unsupported
Indicates a virtual environment that does not support the field.
-
--: Indicates that the field is supported by all virtual environments supported by PFM - RM for Virtual Machine.
