Configuring the Composite Agent Level monitor in TrueSight

PATROL for Composite Attributes enables you to create and monitor custom attribute using one or more existing monitor attributes running on a PATROL Agent. The KM constructs a composite monitor using a logical or arithmetic expression on existing monitor attributes. This topic provides information about how to configure agent-level monitoring in the Composite Attributes KM by using the TrueSight console.

To configure agent-level monitoring in the KM, set the following preferences on the Add Monitoring Configuration dialog.

For example: CPUHealth

Composite Attribute Name

Specify an attribute title to represent the composite attribute in the TrueSight console.

For example: Processor Load

Expression Type

Click  to add the source attribute list for monitoring.

Source Attribute List
Attribute Path Variable

Specify a variable name for an existing attribute that is used for creating an expression.

For example: Attribute CPUprcrLdleTimePercent of Processor monitor can be specified as CPU_IDLE_TIME.

Attribute Path

Specify the path of the monitor attribute that is used for creating the expression. Use this format: /Application class/Application Instance Sid/Parameter. For more information on how to find the path of the attributes, see Agent actions.

For example: /NT_CPU/CPU_0/CPUprcrIdleTimePercent

Create expression using Attribute Path Variables list

Enter a logical/arithmetic expression using variables specified in the attribute list.

For example: CPU_IDLE_TIME > 70

Polling Interval (in minutes)

Specify the interval between two consecutive statistical data polls.

Default: 5 minutes

Logical Expression Alert Options
When Expression evaluates to

Select the evaluation type:

  • True
  • False
Alert Type

Select the alert type:

  • Critical
  • Warning
Parent Configuration
Parent Instance Name
(Application Class/Application Instance Sid)

Specify the instance name that is used as a parent for the created instances. Use this format: Application Class/Application Instance Sid. By default, all the instances are created under /COMPOSITE_CNTR/COMPOSITE_CNTR.

For example: /NT_HEALTH/NT_HEALTH

Note

If the path is left blank or invalid, instances are not created.

JAVA Home

Specify the full path of the JRE directory on the PATROL Agent server. By default, PATROL for Composite Attributes uses JAVA Runtime Environment (JRE) that is installed in the PATROL Agent.

Optional JVM ArgumentsSpecify additional Java process arguments.
