Natural Monitor (NM) provides response time reports. This section discusses the types and components of these reports and how they are created, modified, and used.

This section covers the following topics:

• What is a Response Time Report?

• Accessing the Response Time Subsystem

• Starting or Restarting (Refreshing) a Report

• Listing Reports

• Accessing Natural Monitor Tables

• Using Vertical and Horizontal Graphs

• Purging Report Definitions and Started Reports

What is a Response Time Report?

The Response Time Subsystem enables you to retrieve information about the response times experienced by end users of Natural under the Customer Information Control System (CICS).

Response time is the amount of time, in seconds, required to process a user's transaction. A transaction is registered each time the Enter key or a PF key is pressed.

Response time information is collected by the Natural Monitor processor according to instructions in a response time report definition which consists of the following:

• A set of parameters specifying the data to be captured.

• A set of report and historical data parameter options for specifying conditions of report processing.

• A set of processing rules identifying the conditions under which that data is to be captured.

The Edit Report (ER) function provides a fill-in-the-blank screen to help you create or modify a response time report definition. Once you have entered all parameter values and processing rules on the Edit Report Definition screen, you can issue the SAVE command to write the report definition to the Natural Monitor repository file.

Data accumulation for a particular report begins when you start the report. Report results are automatically saved until the report is refreshed (restarted) or purged.

A report may be viewed online. Report results are displayed as tables and graphs.

Two response time report definitions are supplied with Natural Monitor. These reports may be used without change, or they may be customized to meet the requirements of your particular site. You may also create your own reports.

What are Report Processing Rules?

Report processing rules allow you to restrict the data that a report collects. Four fields are used to specify processing rules:

• TP User ID

• Transaction program name

• Natural application

• Natural program

Each field may contain one of the following processing rules:

• A blank (collect all data)

• A single value

• A wild card

For example, the user ID SAGAA is a single value, and SB* is a wild card created by placing an asterisk after at least one other character. This wild card will result in all user IDs beginning with the characters SB being selected for processing.

Alphanumeric or numeric characters may be entered, but a hexadecimal value is not permitted.

If data is entered in more than one field, Natural Monitor uses AND logic for data collection.

How are Reports Displayed?

The following displays are available for each report:

• Detailed Records providing information sorted by user

• Transaction Summary providing information sorted by transaction

• Vertical Graph

• Horizontal Graph

Detailed Records Display

The Detailed Records display provides detailed response time statistics for transactions related to specific user IDs. The Detail Record parameters in the report definition determine when, how many, and what kind of detail records are to be generated. Detailed records can be viewed online using the Detailed Records display.

Transaction Summary Display

The Transaction Summary display provides both detailed and summary response time statistics. The detailed statistics are specified for a particular transaction name and Natural application (library); the summary statistics are specified for a particular transaction name, regardless of the Natural application.

Transaction Summary reports are produced when the Transaction Summary parameter is set in the report definition; the report results are available online using the Transaction Summary display.

Graphic Display

Reports may be viewed as tables or graphs. Both vertical and horizontal graphic displays are available. The interval, in seconds, for which graphs are generated is set using the Graph parameter in the report definition.

What Reports are Supplied with Natural Monitor?

Natural Monitor supplies two reports which can be used without modification or can be customized to meet the requirements defined for your site:

• The HIGHEST RESPONSE report lists the transactions that have the highest response times, up to the maximum number of records allowed for the report (default = 50). This report allows the user to identify the transactions with the slowest response time of all monitored transactions.

• The SYSTEM RESPONSE TIME report lists the most recent transactions that exceed the response time threshold set for this report (default = 3.5 seconds).

The supplied reports can be viewed online in table or graphic form.

How are Reports Listed?

Three types of lists are used to manage reports:

• Report definition lists of report definitions and started reports.

• Started report lists of all reports that have been started and may be accumulating data.

• History report lists of all reports containing historical data.

How are Reports Named?

A report name may be up to 32 alphanumeric characters in length. It may contain blanks and any special characters except the following:

If the report name is blank, or if the report name you have entered is new to Natural Monitor, the following message is displayed on the Edit Report Definition screen:

REV00275 - NEW REPORT DEFINITION

If this message does not appear, Natural Monitor has recognized the report name you entered as an existing report. Any changes you make on the Edit Report Definition screen will modify the existing report.

You may change the report name from the Edit Report Definition screen by overtyping the name in the Report Name field with a new name and pressing Enter.

The following PF keys are provided to help process report definitions:

Modifying Report Parameters

When you access the Edit Report Definition screen, parameter values are already entered for the report:

• If you accessed an existing report definition, the parameter values reflect the current definition for that report.

• If you are creating a new report definition, the values represent the default values set in P-NMCONF by your Natural Monitor system administrator.

You may change the parameter values on the Edit Report Definition screen, and you may add, modify, or delete processing rules for the report definition.

The parameters shown on the Edit Report Definition screen are described in the following sections.

Graph Parameter

The following field contains one of the parameters used to graph reports:

Detail Records Parameters

The following fields contain values which specify when and if detailed records are to be generated for a report:

Transaction Summary Parameter

The following field is used to set the summary option:

Report Options

The following fields control whether a report is to be autostarted, the interval at which historical data is to be written to the Natural Monitor repository file, and whether the report data collection is to be refreshed after this data has been written:

注意:
The Report Options are processed by the Natural Monitor History subsystem. This subsystem must be installed for these options to take effect.

Controlling Color and Monochrome Attributes

The Response Time Interval and Response Time Threshold parameters are used to control the color and monochrome attributes of response time graphs that display totals. Response times which exceed the Response Time Threshold are shown on color graphs in red and on monochrome graphs as asterisks (*).

Adding, Modifying, or Deleting Processing Rules

Also shown on the Edit Report Definition screen are several fields which control processing rules within Natural Monitor.

Processing rules are used to restrict the accumulation of response time data to specific TP users, programs, Natural applications, or Natural programs, or to a specific set of these values.

When entering data, alphanumeric and numeric values are permitted; hexadecimal values are not permitted.

Each field may contain one of the following processing rules:

Saving a Report Definition

When you have made all necessary changes on the Edit Report Definition screen, you can save the report definition two ways.

To save the report definition

1. Press PF5 (Save); or

2. Enter SAVE on the command line and press Enter.

A new report definition does not become active until you start it. If you change parameters for an existing report, the new parameter settings do not become active until the report is refreshed.

Starting or Restarting (Refreshing) a Report

A report does not begin accumulating data until it is started. Once a report is started, tables and graphs of response time data are generated based on the parameters in the report definition.

New reports are started; started reports that have been modified and saved are refreshed. A report can be refreshed as often as necessary.

The following commands may be used to start or refresh a report:

If you attempt to start a report that has already been started, the following message appears:

The report listed below is already started. Do you want to REFRESH it?

Type Y at the cursor and press Enter to REFRESH the report; type N and press Enter to retain the started report without any of its current modifications.

Starting a Report

A report is started by issuing a start (ST) command. The ST command is issued for an existing report definition that you select. How you start a report depends on your location.

To start a report

1. From any screen within Natural Monitor, type the following string on the command line and press Enter:

   RT ST reportname 

2. From any screen within the Response Time subsystem, type the following string on the command line and press Enter:

   ST reportname 

3. From the list of report definitions, type ST on the selection line preceding the name of the report to be started and press Enter.

注意:
On the list of report definitions, a started report is identified by a greater than symbol (>) preceding the report name.

After you have saved a report definition, you may start a report directly from the Edit Report Definition screen.

To start a report directly

1. Press PF6 (Start); or

2. Type ST on the command line and press Enter.

Once a report is started, the following message appears:

REV00092 - REPORT HAS BEEN STARTED

Natural Monitor then begins to accumulate data based on the parameters in the report definition that you chose.

Other than the ST command, the START command starts the Natural Monitor history session.

Refreshing a Report

To restart a report

• Enter the REFRESH (RF) command.

The REFRESH command is issued for the started report you select. When you refresh a report, all tables and graphs for the report are deleted, and new data is generated based on the current parameters in the report definition. There are three ways to perform a refresh.

To refresh a report

1. From any screen within Natural Monitor, type the following string on the command line and press Enter:

   RT RF reportname

2. From any screen within the Response Time subsystem, type the following string on the command line and press Enter:

   RF reportname

3. From the list of started reports or the list of report definitions, type RF on the selection line preceding the name of the report to be refreshed and press Enter.

On the list of report definitions, a started report is identified by a greater than symbol (>) preceding the report name. If you issue the RF command for a report that is not started, Natural Monitor automatically starts the report.

Once a report is refreshed, Natural Monitor begins to accumulate new data based on the parameters in the report definition that you chose.

Listing Reports

Three different lists of report names are available from the Response Time Subsystem menu:

• Report definitions

• Started reports

• History reports

In addition, a list of historical snapshots is available for any report listed on the History Reports screen.

The following screen-positioning PF keys and commands are available from the report lists:

注意:
There is no PF key available for the TOP command.

Using the PREV or NEXT command, you may access earlier or later historical snapshots.

To access earlier historical snapshots

• Type the command PREV on the command line of any historical snapshot screen and press Enter.

To view later historical snapshots

• Type the command NEXT on the command line and press Enter.

Accessing Natural Monitor Tables

The following tables may be generated for any response time report in Natural Monitor:

Each table consists of one or more screens of data. The data generated from each of these tables is derived from the parameters entered in the report definition (Edit Report Definition screen).

The Detailed Records table provides response time statistics for individual transactions for individual users. A Detailed Records display is generated for a report only if the Detail Record parameters were entered on the Edit Report Definition screen for a report definition.

The Transaction Summary table provides response time statistics for transactions executed in Natural. A Transaction Summary display is generated for a report only if the Transaction Summary parameter of SUM or DET was entered on the Edit Report Definition screen for that report definition.

注意:
Both current and historical data are available for the Detailed Records table. Historical data is not available for the Transaction Summary table.

Accessing the Detailed Records Table

There are five ways to access the Detailed Records screen.

To access the Detailed Records Table

1. From any screen within Natural Monitor, type the following string on the command line and press Enter:

     RT VD reportname 
   

2. From within the Response Time subsystem, type the following string on the command line and press Enter:

     VD reportname 
   

3. From any non-list display within the Response Time subsystem, type VD on the command line and press Enter. The last accessed report will be displayed.

4. From the list of Report Definitions or the list of Started Reports, type VD in the Sel column next to a started report and press Enter.

5. From the Expanded List for a history report, type VD in the Sel column next to a historical snapshot and press Enter.

The Detailed Records screen for a particular report appears as shown in the example below:

The sample screen above is a summary version indicating that the Transaction Summary parameter in the related report definition is set to the value SUM.

Each summary table is marked with **SUM** in the Natural Appl field.

If it is set to the value DET, the default report would be the detailed version of the Transaction Summary table.

The detailed version includes the Natural application (Natural Appl) for each root transaction program (Trans Name).

The Transaction Summary table is sorted in alphabetic order based on the transaction name. If a detailed version of the table is accessed, a secondary sort is performed by Natural application.

The following are the additional PF keys and commands available on this screen:

注意:
There is no PF key available for the TOP command.

You may use PF5 (Det) and PF6 (Sum) to toggle back and forth between the detailed and summary versions of the Transaction Summary table.

Statistical Fields on the Transaction Summary Table

The fields available on the Transaction Summary screen are:

Using Vertical and Horizontal Graphs

Response time reports are available as vertical and horizontal graphs which may be accessed from the following lists:

• Report definitions

• Started reports

• Expanded list of historical snapshots

To access a graph

• Enter either of the following commands in the Sel column for a particular report (or historical snapshot) and pressing Enter:

Once a default vertical or horizontal graph has been accessed, you may access similar graphs of three sets of statistics.

To display additional graphs

• Use the commands listed below.

The Response Time Interval in the report definition (Edit Report Definition screen) determines the whole or fractional number of seconds used to graph the response time intervals on each graph. On the vertical graph, intervals are designated as Response Time Intervals in Seconds. On a horizontal graph, intervals are designated as Response Time Range.

A graph may be displayed in color or noncolor; the availability of color depends on whether you are using an extended data stream (EDS) terminal. The COLOR ON command displays a color graph; the COLOR OFF command returns to a noncolor display.

Interpretation of Graphs that List Totals

A vertical or horizontal graph of total transactions or total calls is interpreted in terms of two parameters set in a report definition (Edit Report Definition screen): the Response Time Interval and the Response Time Threshold. The following gives the physical manifestation of that interpretation as well as describing it:

注意:
The symbol shown in the table is used when the display is not in color.

The following are several examples of how to interpret the values on these graphs:

• For a good response time:

  If the Response Time Interval = 0.5, all transactions with a response time under 0.5 seconds are displayed in green or with the minus sign character (-).

• For a warning:

  If the Response Time Interval = 0.5 and the Response Time Threshold = 3.5, all transactions with a response time between 0.5 and 3.5 seconds are displayed in yellow or with the equal sign character (=) when not in color.

• For a poor response time:

  If the Response Time Threshold = 3.5, all transactions with a response time that exceeds 3.5 seconds are displayed in red or with the asterisk character (*).

Interpretation of Graphs that List Averages

A vertical or horizontal graph of average calls is interpreted in terms of average number thresholds as follows:

注意:
The symbol shown in the table is used when the display is not in color.

The following are several examples of how to interpret the values on these graphs:

• For a good response time (when the threshold is 25):

  If an average of 20 database calls is listed within the interval of 1.0 to 1.5 seconds, it is displayed in green or with the minus sign character (-).

• For a warning (when the threshold is 50):

  If an average of 40 database calls is listed within the interval of 1.5 to 2.0 seconds, it is displayed in yellow or with the equal sign character (=).

• For a poor response time (when the threshold is greater than 50):

  If an average of 70 database calls is listed within the interval of 2.5 to 3.0 seconds, it is displayed in red or with the asterisk character (*).

Commands Used to Control Graphs

In addition to the commands and PF keys that are generally available within the system, the following special commands and PF keys control the various types of vertical and horizontal graphs available:

See Function Codes and Commands for a description of all function codes, PF keys, and commands available within Natural Monitor.

Accessing a Vertical Graph

The command VW enables you to view graphs vertically. There are two ways to use it.

  84.3% of the total of 339 transactions, or 286 transactions, experienced a response time between 0 and 0.49 of one second.

• For a graph displaying the % of total calls:

  5.5% of the total of 21,930 calls, or 1,228 calls, may have experienced a response time between 1.5 and 1.99 seconds.

• For a graph displaying average calls per transaction:

  an average of 225 calls per transaction (total: 675) may have occurred between 2.0 and 2.49 seconds.

Purging Report Definitions and Started Reports

The following commands enable you to purge your report definitions and started reports. These commands are available from the list of report definitions and the list of started reports by entering

To purge a report definition

• Enter the command PR in the Sel column preceding the selected report and press Enter.

To purge a started report

• Enter the command PS in the Sel column preceding the selected started report and press Enter.

In both cases, the following message appears:

Please confirm PURGE request for: reportname (Y or N).

• Verify that the correct report has been selected.

• Type Y at the cursor position and press Enter to purge the report; or

  type N and press Enter to retain the report.

Purging a Started Report

When you delete a started report, you delete only the current data accumulated by the report. The related report definition is not affected and can be modified for use as another report. Historical snapshots for the report are also retained.

Before you purge a started report, remember that a started report can be refreshed (restarted) using a modified report definition. A restarted report retains historical snapshots generated using the previous report definition.

Purging a Report Definition

It is possible to purge a report definition without purging the related started report. However, that started report cannot thereafter be modified (that is, refreshed or restarted).

Before you purge a report definition, remember that a report definition can be modified for use with another report. You might decide to delete a report definition that has never been started and will never be started.

Purging Historical Snapshot(s)

You may decide to purge one or more of the historical snapshots available for a particular started report. For instance, you might decide to purge the oldest historical snapshot(s). Purging a historical snapshot has no effect on the started report or its associated report definition.

To purge a historical snapshot

• Enter the command PH in the Sel column preceding the selected report and press Enter.

  The PH command is available from the list of historical reports, the list of report definitions, the list of started reports and the expanded list of historical snapshots. In addition, this command is available in the command line of the expanded list of historical snapshots screen.

To purge a marked range - start

• In the expanded list of historical snapshots, enter the command PX in the Sel column preceding the historical snapshots and press Enter.

To purge a marked range - end

• In the expanded list of historical snapshots, enter the command PY in the Sel column preceding the historical snapshots and press Enter.

If the range of historical snapshots to be purged is not complete, the following window appears:

    Purge report(s)
      Date/Time From __________  _____
      Date/Time To   __________  _____
  

The following date formats are accepted:

The following time formats are accepted:

If the range of historical snapshots to be purged is complete, the following window appears:

    Please verify PURGE request for
    the date and time listed below:
    From: 1998/03/17  00:00:00
    To:   1998/03/17  23:59:00
  
            ( Y/N )  Y
  

Verify that the correct report range has been selected; then type Y at the cursor position and press Enter to purge the report(s); type N and press Enter to retain the report(s).
