The PATROL Agent product monitors a system according to the instructions provided by loaded PATROL Knowledge Modules (KMs). PATROL Agents are a core component of the Infrastructure Management architecture for monitoring and managing your IT infrastructure. A PATROL Agent offers reliable collection of data from your monitored systems by guaranteeing delivery of event data and instance data to the TrueSight Infrastructure Management Server. TrueSight Infrastructure Management 10.5 supports PATROL Agent version 9.5 and later. However, to use the KM deployment feature, you need PATROL Agents version 10.0 and later.

A PATROL Agent performs the following functions:
PATROL Agent events are considered internal intelligent events and are mapped to the instance object they belong to. This monitor instance association of PATROL events facilitates Probable Cause Analysis, leveraging categorizations (for example, Database, Application, Server, Network, and so on).
The PATROL Agent pushes data as it is collected to Infrastructure Management. The data is streamed from the PATROL Agent to the Infrastructure Management Server without buffering, minimizing latency for data, events, and instance information. The behavior of data delivery depends on the type of data to be sent. In Infrastructure Management, data can be divided into three types:
Infrastructure Management introduces an acknowledgement mechanism whereby the PATROL Agent receives an acknowledgement for the data it sends. This acknowledgement mechanism varies depending on the type of data being sent by the PATROL Agent. This mechanism is applicable if the PATROL Agent or any component of Infrastructure Management goes down during execution. The acknowledgement mechanism applies only to instance data and event data
PATROL Agents send performance data and events to the Integration Service which in turns filters the data and events before passing the data to the Infrastructure Management Server. The Integration Service performs the following functions for PATROL Agents:
It ensures that the data between the Infrastructure Management and the PATROL Agent is in sync by streaming data and events to the Infrastructure Management Server and providing near real-time information about application classes and instances (along with data and events) available in the PATROL Agent.
The Solution Administrator configures PATROL and Infrastructure Management such that events are sent from PATROL to the Integration Service. The Integration Service then routes these events to the cell for event processing.
PATROL events reach the TrueSight Infrastructure Management Server through the cell, where they are processed and and displayed in the Infrastructure Management operator console or routed to the TrueSight Presentation Server for display in the TrueSight console. IT Operations can then monitor for critical events and perform event operations or other functions, such as Probable Cause Analysis.

Solution Administrators configure PATROL Agents from the TrueSight console. For information, see Managing Infrastructure Management devices from the TrueSight console.
