Natural Monitor administrative functions are discussed in two sections:
the User Profile System, which is used to generate profiles that define access rules for Natural Monitor users; and
functions that pertain specifically to Natural Monitor.
This section covers the following topics:
注意:
See Installing Natural Review,
Storage
Requirements, for an explanation of the effect of many
users on CICS SHARED storage requirements.
The User Profile system provides a series of menus to help you generate profiles that define access rules for Natural Monitor users. You may create profiles for new users, change access rules for existing users, and purge user profiles that are no longer required.
Natural Monitor provides a default profile to allow access for users who
do not have a profile defined for them. When a user logs on, Natural Monitor
checks the Natural library SYSRNM for the user's profile. If one
is not found, the default profile is used.
The default profile is also used as a basis for creating user profiles. When a profile for a new user is generated, the default profile is copied. The new profile may then be customized to suit the needs of the user.
注意:
The default profile provides unrestricted access to Natural Monitor
systems and functions. It is recommended that you first create a user profile
for the system administrator and other privileged users; then modify the
default profile so that it conforms to the needs of the majority of
users.
To access the User Profile System
Enter the UP code on the command line of the Natural
Monitor Main Menu and press Enter.
The User Profile System menu appears as shown below:

The following commands enable you to create and edit profiles, and display lists of existing profiles:
| Command | Description |
|---|---|
EU |
Edits a profile for a new or existing user. |
LU |
Displays a list of existing user profiles, including the default profile. |
From the list of existing user profiles, you can select a particular profile to be edited or purged.
You do not need to create a user profile for each user of Natural Review. By customizing the default profile so that the access rules meet the needs of the majority of Natural Monitor users, you eliminate the need for individual user profiles.
You can access the Edit User function to edit the default profile in two ways.
To access the Edit User screen
From any screen within Natural Review, type UP EU
DEFAULT on the command line and press Enter.
From any screen within the User Profile system,
type EU DEFAULT on the command line and press
Enter.
The following Edit User screen is displayed:
16:59:54 ***** R E V I E W ***** 2006-03-02

The User Profile field usually refers to the user ID
corresponding to the profile; in this case it contains the word
DEFAULT. The categories on the screen refer to types of access
rules as described in the following table:
| Category | Description |
|---|---|
General |
Access rules that affect all of the systems within Natural
Review. Valid values are Y/N.
|
NATURAL MONITOR |
Access rules pertaining to the Natural Monitor system. Valid
values are Y/N.
|
For the user's default profile, you need to modify the general access rules in addition to those pertaining to Natural Monitor.
When you select the general access rules, the General window appears as shown in the following screen:
General

You may modify access rules by typing over the settings displayed on the screen. When you have made all of the changes to a particular group of access rules, you have the following options:
To exit without saving the changes, press PF3 or enter
the EXIT command.
To save the changes temporarily while you edit the next access rules
screen, press PF6 or enter the ACCPT
command.
To save the changes to the Natural library, press PF5 or
enter the SAVE command.
If you selected more than one category, pressing PF3 or PF6 displays the next access rules screen instead of returning you to the previous screen.
To create a user profile
From any screen within Natural Review, type the following string on the command line and press Enter:
UP EU userid
From any screen within the User Profile System, type the following string on the command line and press Enter:
EU userid
The User Profile System creates a profile for the user by copying the default profile. It then displays the user profile for editing, and the following message appears at the bottom of the screen:
REV00101 - NEW USER PROFILE
If you wish to customize the user's profile, mark the appropriate categories by typing a character on the line following your selection:
To change access to two Natural Monitor systems, mark the General category.
If you wish to modify access to certain Natural Monitor system functions, mark the Natural Monitor category.
When the profile provides appropriate access privileges for the user, press PF5 to save the profile to the Natural library.
Refer to Customizing the Default Profile for information regarding access rules for the various categories.
The List User Profiles (LU) function
displays a list of user profiles that are stored in the Natural library
SYSRNM.
To access the list of user profiles
Enter the code LU on the command line of the
User Profile System menu and press Enter.
The User Profiles screen, similar to the one shown below, is displayed:

Natural Monitor has two Natural user exits which are applicable to the Natural Monitor components:
P-UEXIT1
P-UEXIT2
These exits are located in SYSRNM, the Natural Monitor
system library in Natural. They can be modified using the Natural
editor.
This program is invoked when the online portion of Natural Monitor is entered. You may insert code into this program to satisfy site-specific needs.
Possible uses for this exit include:
Setting colors on (SET CONTROL 'T3279').
Turning the PC mode on or off.
注意:
This program must not alter the Natural stack, and it
must end with a STOP command.
This program is invoked when the online portion of Natural Monitor is terminated. You may insert code in this program to alter the processing that occurs when terminating Natural Review.
Possible uses for this exit include:
Terminating your Natural session.
Logging on to another Natural application.
Returning to a previous Natural application (using
SETUP/RETURN).
Each time a transaction finishes (a terminal write is performed), Natural Monitor creates a record that contains information about the resources consumed by that transaction:
the response time for the transaction;
the number of database calls issued for the transaction;
the total database elapsed time and command time for all calls issued; and
information about the user who performed the transaction.
A user exit (RNMRTUEX) is provided with Natural Monitor to
allow the user to handle this information as follows:
examine the record;
process the record; and
accept or reject the record's inclusion into any active Natural Monitor response time reports.
The user can also write this record to a sequential data set or to SMF (System Management Facility) for later processing or as input to a chargeback system.
A sample RNMRTUEX user exit is supplied in the Natural
Monitor source library. A copy book containing a DSECT mapping the
detailed record is also provided.
This user exit can be modified to suit the needs of a user site and must be linked into the Natural nucleus with the rest of the Natural Monitor code in the step that links the Natural nucleus with Natural Monitor (see Installing Natural Review, Step 6 of the Installation Procedure).
The following calling conventions are used to invoke the
RNMRTUEX user exit:
Register contents when entering the user exit:
Register 1: Address of the parameter list
Register 13: Address of an 18-fullword save area
Register 14: Return address in the calling module
Register 15: Entry address within RNMRTUEX
Register contents returned by the user exit:
Register 1: Address of the parameter list
Registers 2 through 13: Must be unchanged.
Content of parameters passed:
Word 1: For record type 1: Response time report detail record
Word 2: Address of the response time report detail record
Return codes passed using Register 15:
Zero(0): Process the record for all active response time reports
Non-zero(0): Reject the record for response time report processing
The Natural Monitor repository file contains Natural Monitor response time report definitions and historical data for response time reports that have a history interval. The historical data can be accessed by user-written applications and used as input for other processing (for example, trend analysis).
The view for this file is called REVIEW-NM-FILE.
The file can be read using the following key definition against the view
field NM-KEY:
1 REPORT-KEY (A50) 1 REDEFINE REPORT-KEY 2 REPORT-SUBSYSTEM (A02) 2 REPORT-DATE (N08) 2 REPORT-TIME (N06) 2 REPORT-NAME (A32) 2 REPORT-SEQ (B02)
where:
| Field | Description |
|---|---|
REPORT-SUBSYSTEM |
RT for the Response Time subsystem.
|
REPORT-DATE |
Date (in YYYYMMDD
format) that the historical data record was written.
|
REPORT-TIME |
Time (in HHMMSS 24-hour
format) that the historical data record was written.
|
REPORT-NAME |
Response time report name for which the historical data record was written. |
REPORT-SEQ |
Record type for the historical data record.
Record type 1 is used for response time interval data
(corresponding to the VD display in the Response
Time subsystem). The first detail record written for a given history
interval will have a REPORT-SEQ = 2, and for each additional
detail record written, the REPORT-SEQ field will increment by
1.
|
Two sample Natural programs are provided in the Natural Monitor library
(SYSRNM) which read Response Time subsystem
historical data. These two programs are called HISTORY1 and
HISTORY2.
HISTORY1 is an example of how to read the response time
interval history data (corresponding to the VW or
VH command in the response time subsystem). For a
specific response time report within a specified date and time range,
HISTORY1 reads all associated response time interval history
records and performs some summary statistical evaluation.
HISTORY2 is an example of how to read the response time
detail history records (corresponding to the VD
command in the response time subsystem). For a specific response time report
within a specified date and time range, HISTORY2
reads all associated response time detail history records and displays summary
information of the 20 detail records had the highest response time.
In addition to the two sample Natural programs, a Natural local data
area (LDA) called L-NMHIST is provided which incorporates fields
from the Natural Monitor DDM. This LDA may be used by user-written programs to
read the Natural Monitor repository file. See Local Data Area View Description
for the contents of this LDA.
See Installing Natural Review, Storage Requirements, for an explanation of the effect of many response time reports on CICS SHARED storage requirements.
Within Natural Monitor, the Natural Monitor administrator modifies the configuration program for the following reasons:
to control the generation of historical data for response time reports;
to control the intervals used for collection; and
to set other response time report parameters.
The administrator uses parameters in the program P-NMCONF
in library SYSRNM to control historical data and other response
time report options.
The P-NMCONF program contains default configuration values
for new response time report definitions. Parameter values set in the
distributed P-NMCONF program are normally not changed until the
default values have been in use for a test period. P-NMCONF
program parameter values generally depend on the site's workload, application
use, and response time.
The P-NMCONF program is a Natural program called from
Natural Monitor code to set defaults in the Natural Monitor global data area.
It can be edited just as any Natural program can be edited.
To access and edit the P-NMCONF configuration program
Type LOGON SYSRNM at the Natural
NEXT prompt and press Enter.
Type EDIT P-NMCONF and press
Enter.
Modify the P-NMCONF program by typing over the existing
values.
注意:
P-NMCONF parameters and values are discussed in the
following sections.
Type STOW and press Enter to
save and catalog the changes.
Type MENU at the prompt to return to
Natural Review.
The changes you make to P-NMCONF take effect
immediately.
The +RT-INTERVAL and
+RT-THRESHOLD parameters are used in conjunction with
one another to control the color and monochrome attributes of response time
reports.
| Parameter | Description | ||||||||
|---|---|---|---|---|---|---|---|---|---|
+RT-INTERVAL |
Specifies the reporting interval (in seconds) used to graph a
report horizontally and vertically. Valid values are 0.1 to
