About role management in Alerts
The roles management feature in Alerts lets you assign roles to users and control whether they will be able to do the following operations:
- View and/or configure Alerts general settings
- View and/or configure Alerts metric settings for specific instances
- View and/or configure Alerts metrics default settings for all instances
- View and/or configure Alerts Precise status metrics settings
- Add and remove Alerts customized metrics
Permission is a combination of permission types (such as:ADMINISTRATE, MONITOR) and operation (such as: VIEW, EXECUTE).
In order to enable the Alerts settings screen, the user needs to have a role with ADMINISTRATE.VIEW permissions. For metric settings, VIEW or EXECUTE permissions should be granted for: Environments, AppTiers, Instances, or Technologies.
To add and remove customized metrics, the user should have specific technology EXECUTE permissions. For Precise status metrics settings control, the user should have Precise technology EXECUTE permissions. Configure permissions and roles in AdminPoint. See Defining roles and users in Precise.
About configuring Alerts general settings
The Alerts, issued by Alerts, are based on information collected by Insight agents, agents of Precise products, or Report Manager agents. See Configuring Alerts general settings.
About configuring Alerts metric settings
The Alerts, issued by Alerts, are based on information collected by Insight agents, agents of Precise products, or Report Manager agents. For most of the metrics, Alerts enables you to launch the relevant Precise product without returning to the StartPoint screen. See Configuring Alerts metric settings.
The Alerts metric settings dialog box includes the following tabs:
- Settings
- Activities
- Copy Metrics Settings
About editing metric properties
You can edit the properties of each metric that is available in your Precise environment, including Cross-AppTiers metrics, such as: FocalPoints, Agents, Processes, and Licenses. See Editing metric properties.
The Metric Properties dialog box includes the following tabs:
- Scheduling
- Thresholds
- Actions
See About metric properties for Action settings.
About metric properties for Action settings
An environment that is monitored by Alerts may generate alerts at any time. Sitting in front of the screen waiting for a metric to go critical may be strenuous and time consuming. Instead, you can set Alerts to inform you about any alert, or to run your repair utility to fix certain problems.
Alerts provides the following action types when an alert is raised:
- Email. Alerts sends a user-defined message to a user-defined recipient. You can set an email action per instance level or per metric.
- Message Box. Alerts displays a user-defined message in a pop-up box on each running Alerts user interface.
- Program. Alerts runs a user-defined program that is stored in the directory:
<i3_root>\products\pulse\userprograms
. - SNMP. Informs your management framework of any changes in the metric status.
- MOM. Alerts sends an alert to the MOM server console.
In the Actions tab you define the rules that stipulate when an alert is triggered.
You can test each action that you define in the Action Types by clicking the Test button (for the Email, Message, and Program action types you must first enter parameters to enable the Test button). This test triggers the action including its dynamic parameters. The dynamic parameters retrieve the values of the last sample (if a metric was not sampled before the test, some of the parameters may hold invalid data). See Using dynamic parameters in actions.
On the lower half of the Actions tab window a metric summary table is displayed indicating:
- Total number of declared email actions
- Total number of declared Message actions
- Total number of declared Program actions and whether or not an SNMP or MOM action is applied to the metric.
The two tables below indicate how rules are applied when issuing alerts (both Near-Critical and Critical) for different alert transitions (applies to the following actions: email, message, and program):
Table 16-1 Near-Critical
Old / New | Critical | Near-Critical | Normal | Not sampled |
---|---|---|---|---|
Critical | Do not issue | Issue | Do not issue | Do not issue |
Near-Critical | Issue | Do not issue | Do not issue | Do not issue |
Normal | Issue | Issue | Do not issue | Do not issue |
Not Sampled | Issue | Issue | Do not issue | Do not issue |

An example for using dynamic parameters in Email or Message actions can be found in the Message text box in the Email tab (default message).
Examples for using dynamic parameters in Program actions can be found in the directory:
<i3_root>\products\pulse\userprograms
.
The following examples are provided:
action_example.bat
(for Windows). To activate this file, set the following command line:- action_example.bat $METRIC_ALERT $METRIC_TIME $METRIC_NAME $METRIC_VALUE
action_example.sh
(for Linux or UNIX). To activate this file, set the following command line:- action_example.sh $METRIC_ALERT $METRIC_TIME $METRIC_NAME $METRIC_VALUE
For both examples, when Alerts activates the file, it writes to a log file information about the alert, which can be helpful for troubleshooting alerts. The log file name is action_example.log
and it contains the following text:
==================
ALERT: <$METRIC_ALERT result>
TIME: <$METRIC_TIME result>
Metric <$METRIC_NAME result> showed value
<$METRIC_VALUE result>.
See Email action properties, Message action properties, Program action properties, SNMP action properties, and MOM action properties.
About setting Alerts SNMP connectivity
SNMP (Simple Network Management Protocol) is the Internet standard protocol for network management software. Alerts supports connectivity to an SNMP Framework using the following Protocol Data Unit (PDU) operations:
- SNMP get Operation. Alerts FocalPoint can receive SNMP Get requests from an SNMP manager to read the Precise Alerts database accordingly.
- SNMP trap operation. When Alerts SNMP server is enabled for actions, Alerts sends SNMP traps to your SNMP manager in case an alert state is raised or resolved.
SNMP Get Operation
Alerts has an extended user interface, allowing you to set metric definitions and to view the samples results. However, you may want to use your SNMP manager to receive metric specific data from Alerts.
To enable this option, first create a Management Information Bases (MIB) file. The MIB file maps the Alerts database entities, such as the various environments, various instances, and the metrics relevant for each of the instances. Because different sites have different environments, instances, and so on, you must adjust the Alerts MIB file to each site.
Creating an MIB file
Alerts FocalPoint creates the MIB file and displays its status (success or failure) on the standard output. The newly created MIB file name is InformForAlertsMib.mib and is stored in the following directory:
<i3_root>\products\pulse\userprograms
Information about the MIB creation process can be found in the log file:
<i3_root>\logs\alerts.mibbuilder.log
To create an MIB file
- On the server that Alerts FocalPoint is installed, run the following command, according to the server operating system, from the Precise root directory:
On a Windows NT server. <i3_root>\products\pulse\pulsefocal\bin\ createalertsmib.bat
On a Linux or UNIX server. <i3_root>/products/pulse/pulsefocal/bin/ createalertsmib.sh
Enabling the Get operation
To use your MIB browser to open the MIB file that you have created and browse the different metrics, you must set the Get parameters on both your SNMP manager and Alerts. The examples provided along with the following instructions relate to the CA Unicenter MIB browser, which is an SNMP management application.
To set the get parameters
- Copy the newly created MIB file (InformForAlertsMib.mib) to the SNMP server's MIBs directory.
For example in CA-Unicenter:<TND_root>\SERVICES\CONFIG\MIBS
. - Upload the MIB file to your SNMP MIB browser.
For example in CA-Unicenter, run the following command from the TND directory
<TND_root>\SERVICES\CONFIG\MIBS:
ldmib -n oidprecise -m InformForAlertsMib.mib - In the SNMP tab of Alerts Settings dialog box, set an available listening port in the SNMP port box. This port will receive the Get requests from your SNMP MIB browser. Also, set the SNMP version according to your MIB browser.
Browsing the Alerts MIB
Before you start browsing the Alerts MIB, it is recommended to be familiar with the following issues:
- Technology representation
- Identifying environments and instances in the MIB
- Identifying metrics in the MIB
- Identifying property fields in the MIB
- MIB structure
Technology representation
The MIB tree shows the technologies of the Precise environment as the numbers 1 - 15. The table below shows how each number in a MIB tree is mapped to a technology.
Table 16-5 MIB tree mapping
MIB number | Mapped to ... |
---|---|
1 | Oracle |
2 | Sybase |
3 | MS-SQL |
4 | Tuxedo |
5 | Web |
6 | J2EE |
7 | SAP |
8 | Oracle Applications |

11 | EMC Storage |
12 | Other |
13 | OS |
14 | Precise status |
15 | WebSphere MQ |
16 | Sybase Replication Server |
17 | DB2 |
Identifying environments and instances in the MIB
Alerts displays environments and instances by their names (environment_name, instance_name
), while the MIB presents them by their identifiers (environment_id, instance_id
).
To identify environments and instances in the MIB
- Retrieve a mapping table that maps the environment and instance names to their identifiers by running the following SQL statement in the Alerts schema:
select
INCE_ID INSTANCE_ID, INCE_NAME
INSTANCE_NAME, INEN_ID
ENVIRONMENT_ID, INEN_NAME
ENVIRONMENT_NAME
from
PS_INCE_INSTANCE_INSTANCE, PS_INII_INSTANCE_APPTIER
INSTANCE_APPTIER, PS_INAP_APP_TIER APPTIER,
PS_INEN_ENVIRONMENT ENVIRONMENT
where
INCE_ID = INII_INCE_ID AND
INAP_ID = INII_INAP_ID AND
INAP_INEN_ID = INEN_ID AND
INCE_DELETED = ‘F’ AND
INII_DELETED = ‘F’ AND
INAP_DELETED = ‘F’ AND
INEN_DELETED = ‘F’ AND
Identifying metrics in the MIB
Alerts displays metrics by their names (metric_name
), while the MIB presents them by their identifiers (metric_id
).
The mapping table is sorted by the metric name.
To identify metrics in the MIB
- Retrieve a mapping table that maps between the metric names and their identifiers by running the following SQL statement in the Alerts schema:
select indicator_id,indicator_name, from pulse_indicators order by indicator_name;
Available property fields in the MIB
The table below describes the available property fields for a metric.
Table 16-6 Available property fields in the MIB
No. | Field | Description | Applies to |
---|---|---|---|
0 | Value | Specifies the metric's value. Same as the dynamic parameter: Displayed in the Value metrics tab only. In case of a parent metric, only the sub-metrics show this field. | Get |

MIB structure
The Alerts MIB structure complies with the Alerts SNMP Object Identifier (OID) structure. The OID of the Alerts Get requests for a specified metric is:
1.3.6.1.4.1.2608.1000.8.envId.techId.instId.metricId.field
Where field
is the field number as specified in the metric fields table (previous table). You can identify this OID from the SNMP trap messages, using the $METRIC_TOKEN
dynamic parameter.
SNMP trap operation
Using SNMP trap operations, you can automatically receive alerts in your SNMP server. The trap message contains critical information about the trap alert.
After receiving the SNMP trap message, you can use your SNMP manager to resolve the problem, notify the management level.
Alerts supports both SNMP message versions, SNMPv1 and SNMPv2. Alerts sends traps when a change occurs in a metric severity level, that is, when the metric state is changed between the following states: Critical, Near-Critical, Normal, and Unsampled.
Alerts trap message
The following is an example of an Alerts'SNMP trap message:

From the above table you can see that the Varbind Object ID for all the metrics of an Alerts trap starts with: 1.3.6.1.4.1.2608
The table below describes the SNMP trap structure. The abbreviated OID (Object ID) is the number after the last period on the varbinds table (as stated before, the rest of the number is the same for all varbinds).
Table 16-7 SNMP trap structure
Description | Abbreviated object identifier (OID) |
---|---|
Metric | 7 |
Instance | 8 |
Technology | 10 |
Machine | 11 |
AppTier | 12 |
Environment | 13 |
Sampled on | 6 |
Alert | 1 |

The trap can be parsed with a commercial trap catcher according to the position of the varbinds or their OID. The following apply only to the last varbind on the table (OID=0):
- All the fields with the dollar sign ($) are dynamic parameters. Alerts translates these parameters before sending the SNMP trap.
- Spaces inside items are converted to the underscore character (_) to allow saving the position.
To enable identification of the alerted metric's OID, required for the Get and Set requests, the SNMP action supports the following dynamic parameter: $METRIC_TOKEN
. This dynamic parameter is the MIB OID of the metric. In addition, consider the following:
- All items in the SNMP trap message keep their position, so you can access particular message items using built-in SNMP functions.
- You can set all metrics of an instance to trigger SNMP actions through the Instances tab of the Settings dialog box.
- In case of parent metrics, Alerts sends an SNMP trap message only to the parent metric.
To cause the SNMP trap to act as in version 7.5, add the following parameter to the Alerts FocalPoint registry, and then restart the Alerts FocalPoint:
....\products\i3fp\registry\products\alerts\pulsefocal.xml
Pulsefocal\snmp\trap
<oldTrapStyle>YES</oldTrapStyle>

Issuing rules for MOM actions
If MOM action is defined for a metric, MOM integration is activated and a MOM action is issued every time a metric's alert changes.
For disabled metrics, the metric's initial status is not reported to MOM. The metric is only reported when the disabled status changes to another status. Disabled metrics do not appear in the MOM console.
Display of MOM alerts in the MOM server
The MOM alert can be displayed only when integration between Alerts and the MOM server is activated and the registration process is completed successfully. A MOM alert can be the result of either clicking the Test button or of a real action performed by the Alerts FocalPoint.
When you open the MOM Operator Console, select Alert Views in the Alert Views pane. The figure below displays the MOM Operator console user interface
Figure 16-1 MOM Operator console
If you have successfully installed the Precise Management Pack (see Precise Installation Guide), you will see a Precise folder in the Alert Views tree. This folder displays on the Alerts View Results pane, all actions generated as MOM alerts.
The Precise folder is divided into sub-folders, one for each of the supported technologies. To see only the alerts of a single technology, select that technology's folder.
Each alert in the Alerts View Results pane represents a metric that monitors a single instance integrated with MOM. When a metric triggers a MOM action for the first time, a line will be added to the pane. If a Customized metric that is integrated with MOM is deleted, the entry’s Resolution State will change to Resolved, and the entry will be removed according to your Database Grooming properties.
On the Alert Details pane you can see details for the selected MOM alert. The details only include basic metric information. That is, the current value of the metric will not be displayed. To investigate the metric's value further, you will need to open the Precise user interface.
The table below shows the different MOM severities displayed in the MOM operator console according to the Alerts alert levels.
Table 16-8 Alert level names in the MOM operator console
Alerts alert | MOM severity |
---|---|
Normal | Success |
Near_Critical | Warning |
Critical | Error |
Critical (Key Metric) | Critical Error |
Not Sampled | Unknown (alert will not be seen in the MOM console) |

Alerts is delivered with a set of predefined MOM alert actions for metrics monitored by Precise Microsoft technologies.
About creating customized metrics
You can add customized metrics to an AppTier (excluding the Cross-AppTiers), or delete customized metrics.
Alerts allows you to monitor any performance aspects using pre-defined metrics for each AppTier. For data that is not collected by any of the pre-defined metrics, you can create new customized metrics. (Only users with Administrator privilege are allowed to define customized metrics.)
For example, you can create a customized metric that uses a UNIX shell that collects data about the memory size allocated for specific processes (in this case, the metric type is Table because it collects multiple values). The metric will return the data by using a host script. Alerts will display the collected data as a list in the Current tab. The History tab will display the processes behavior over time. The Events tab will trace the alert levels produced by this metric including its failures (Not Sampled status).
When creating a customized metric, it is associated with all instances of an existing AppTier. The customized metrics are part of the Customized set. You can also edit the Thresholds, Sampling, and Actions for each customized metric individually.
To sample customized metrics, InformPoint must be installed on the sampled instance server. In the case of a remote SQL server instance, the InformPoint that samples the instance is the one installed on the remote SQL server collector.
Creating customized executable files
A customized metric can be associated with a host script that you create, so that Alerts operatively monitors a parameter specific to your environment.
Save the host script in the server machine where the sampled instance is running, in the directory:
<i3_root>\products\pulse\userprograms
.
Although the root directory of the running script is <i3_root>
, the program runs from the userprograms
directory.
To simulate a run of customized metric, use a command line shell and type from the Precise root directory:
For Windows operating systems .\products\pulse\userprograms\MYPROG.bat
.
For UNIX or Linux operating systems ./products/pulse/userprograms/MYPROG.sh
.
You can create a customized metric that returns a single value or a list of values. A customized metric that returns a single value is created by apply the following guidelines:
- The script must return a single value to the Standard Output (
echo
command). The type of the value must be numeric or float. Alerts compares this value to the customized metric thresholds to determine the metric alert status. - The script must output only the value. To avoid that commands be printed, Windows scripts must start with
@echo off
. UNIX scripts must start with the shell type, for example#!/bin/ksh
. - You can use dynamic parameters for customized metrics in the command line.
See Using dynamic parameters in customized metrics.
A customized metric that returns a table with multiple values is created by apply the following guidelines:
- The script must return a list of values to the Standard Output (
echo
command). Each line in the output must contain a name and a value separated by a tab (\t only, not a space). The value must be numeric or float. Alerts compares these values to the customized metric thresholds to determine the metric alert status. - The script must output only the value. To avoid that commands be printed, Windows scripts must start with
@echo off
. UNIX scripts must start with the shell type, for example#!/bin/ksh
. - In some operating systems, the tab character may be ignored when printing it using the echo command. In those cases, use the ' character around the text, as follows:
echo 'Alerts 80'
.
You can use dynamic parameters for customized metrics in the command line. See Using dynamic parameters in customized metrics.
It is recommended to test your scripts in your environment before running them through Alerts. For UNIX scripts, verify that the script has rx security permissions.
Windows script examples
The examples for Windows scripts, whose file names end with _example, are listed in the following tables. These files can be found also in any server where InformPoint is installed, in the directory:
<i3_root>\products\pulse\userprograms
The table below shows an example of customized metrics with a single value.
Table 16-9 Example of customized metrics with a single value - Windows
Script file | Script lines | Description |
---|---|---|

Creating customized stored procedures
To monitor a parameter specific to Oracle or SQL Server AppTiers, you can create a stored procedure and connect it to a customized metric of Alerts. The type of your stored procedure, Oracle or MS-SQL, must be according to your PMDB type.
In addition, the stored procedure can be defined only in Oracle or SQL Server AppTier instances. To create Oracle stored procedure metrics, you must install the Precise for Oracle FocalPoint with at least one instance. To create MS-SQL stored procedure metrics, you must install the Precise for SQL Server FocalPoint with at least one instance.
Creating MS-SQL stored procedures
When creating a stored procedure in MS-SQL, apply the following guidelines:
To create MS-SQL stored procedures
- Connect to the database as Precise for SQL Server user.
- Ensure that the name of the stored procedure includes the database name. For Oracle users, the procedure name must not end with a semicolon (;).
- The naming convention for the program in Alerts must be:
databaseName..Procedure()
. Verify that the return value of the execution is a single numeric value (integer).
You can use any procedure and an unlimited number of parameters, including no parameters.
To create an MS-SQL stored procedure
- Apply the following format:
CREATE PROCEDURE user_def @@var1 type1, ...., @@var-n type-n
AS
- Custom query
GO - Use the following format within the call from the customized metric (the code should be entered in the Program box when adding a new Customized Metric):
user_database..user_def val1, ...., val-n
Example of an MS-SQL stored procedure
The following stored procedure enables Alerts to send an email when the number of rows in a table called SALES.ITEMS reaches an amount that you set in the Thresholds tab.
To apply the MS-SQL stored procedure
- Connect to the database schema of the Precise for SQL Server.
- Create the function
user_def
in the user_database as follows:
CREATE PROCEDURE user_def @@sampling_rateint,@@sampling_period int
AS
SELECT count(*) FROM SALES..ITEMS
GO - When you create the customized metric under the MS-SQL instance, set the program name to:
SALES..user_def @SAMPLING_RATE, @SAMPLING_PERIOD
Use dynamic parameters. See Using dynamic parameters in customized metrics.
To test the MS-SQL stored procedure
- Connect to the database schema of the Precise for SQL Server.
- Run the function
user_def
in the user_database as follows:
user_database..user_def sampling_rate , sampling_period
Creating Oracle stored procedures
When creating a stored procedure in Oracle, apply the following guidelines:
To create Oracle stored procedures
- Connect to the database as Precise for Oracle user.
- Ensure that the name of the stored procedure includes the package name and ends without a semicolon (;).
- The naming convention for the program in Alerts must be:
PackageName.ProcedureName()
. - Verify that the return value of the execution is a single numeric value (integer).
To create the Oracle stored procedure package
- Apply the format as follows:
Create or replace package user_defined_pack as
function user_def(var1 type1, .... , var-n type-n)
return return-type;
pragma restrict_references(user_def,WNDS,WNPS);
end user_defined_pack;
/
To create the Oracle stored procedure package body and insert your custom code into the user defined functions
- Apply the following format
Create or replace package body user_defined_pack as
function user_def(var1 type1, ...., var-n type-n) return
return- type is
begin
-- Custom
code end
user_def;
end user_defined_pack; - Use the following format within the call the call from the customized metric (the code should be entered in the Program box when adding a new Customized Metric):
user_database..user_def val1, ...., val-n
You can use any package or function name, and an unlimited number of parameters (including NONE).
Example of an Oracle stored procedure
The following stored procedure enables Alerts to send an email when the number of rows in a table called ITEMS, which belongs to a user called SALES, reaches an amount that you set in the Thresholds tab.
To apply the Oracle stored procedure
- Connect to the database schema of the Precise for Oracle.
- Create the package
user_defined_pack
as follows:
Create or replace package user_defined_pack as
function user_def(sampling_rate number, sampling_period
number, warning_threshold number, critical_threshold number)
return number; pragma
restrict_references(user_def,WNDS,WNPS);
end user_defined_pack;
/ - Run the following script in the Precise for Oracle database schema to create the package body of package user_defined_pack:
Create or replace package body user_defined_pack as
function user_def(sampling_rate number, sampling_period
number, warning_threshold number, critical_threshold number)
return number is
tbl_num_rows number; BEGIN
select num_rows into tbl_num_rows from sys.dba_tables where
table_name='ITEMS' and owner='SALES';
return (tbl_num_rows);
end user_def;
end user_defined_pack;
/ - When you create the customized metric under the Oracle instance, set the program name to:
user_defined_pack.user_def ( @SAMPLING_RATE , @SAMPLING_PERIOD ,
@NEAR_CRITICAL_THRESHOLD , @CRITICAL_THRESHOLD )
Use dynamic parameters. See Using dynamic parameters in customized metrics.
To test the Oracle stored procedure
- Connect to the database schema of the Precise for Oracle.
- Run the function user_def in the user_database with your values as follows:
select user_defined_pack.user_def(sampling_rate,
sampling_period, warning_threshold,
critical_threshold) as value from dual;
Using dynamic parameters in customized metrics
When you set a customized metric, you can use dynamic parameters in the Program command line.
The dynamic parameters in customized metrics are not the same as used in actions.
The table below describes the dynamic parameters that you can use in customized metrics.
Table 16-13 Dynamic parameters
