Event Management The process of assigning responsibility for the investigation of a system-related problem and then tracking activities associated with this event through to closure. Commit The process of globalizing changes made to the PATROL environment from a Developer Console and then piping the change to the Agent(s).

Basic PATROL Architecture Basic PATROL Agent The Agent i s the workhorse of PATROL. At Agent startup, the Agent reads a discovery script from its local file system. Once discovery has taken place, the appropriate KMs are loaded.

Everything the Agent monitors and executes automatically is based on the rules within the KM. It is important to note that Agents live within the boundaries of resources that you allocate to them. This allocation is done at installation.

The more resources you allocate to the Agent, the faster it becomes. The PATROL Smart Agent technology was developed to consume as few resources as possible (on your server, as well as your network). The fewer the applications or features of those applications you monitor with PATROL, the fewer the resources the Agent needs to accomplish its tasks.

The Agent process is made up of several logical modules. It is this modular approach that facilitates addition of new functionality over time..

Solaris and LDAP Naming Services Basic PATRO L Event Manager (PEM). The PATROL Code 39 Full ASCII for Java Event Manager (PEM) enables you to view and manage events that occur on monitored system resources and that are sent by PATROL Agents. PEM is a PATROL tool that helps automate this process. The Agent communicates events to all interested consoles via the event broadcast mechanism.

. Basic PATROL Knowledge Modules The knowled Code39 for Java ge module has three distinct characteristics. At Agent startup, a Knowledge Module is loaded from a file on the Agent s local file system. Similarly, at Console startup, a Knowledge Module is also loaded.

The only time a KM is moved around over your underlying network is when a Developer Console updates knowledge stored at each Agent. A Knowledge Module comprises two major components: discovery rules and scripts. The discovery rules implement the scope defined by the KM developer.

The discovery rules define to the PATROL environment how to determine whether the objects that you want to manage exist and are currently active in the target environment. Once the objects have been discovered, the scripts provide PATROL the intelligence required to implement the purpose of the KM. Parameters are the monitoring component of PATROL.

A parameter monitors the individual units of performance of the targeted application (e.g., CPU utilization, file system capacity).

Associated with parameters are alert ranges, and associated with alert ranges are recovery action scripts.. Basic PATROL Console The PATROL Code39 for Java Console is where the PATROL user initiates ad hoc commands that are executed on the Agents. Ad hoc commands are sourced (the actual command scripts are stored at the Console), and when triggered by the PATROL user, the command scripts are sent to an Agent (or multiple Agents simultaneously) for execution. This approach allows a PATROL Console user to not only view alerts from the agent but also to take troubleshooting, administrative, or corrective actions from the same platform.

These stored commands make up the administrator s toolkit, the chief benefit of running a PATROL console. The PATROL Console running in developer mode is the tool used to manage, update, and modify the PATROL environment s monitoring knowledge. The other option for the PATROL Console is the Operator Console.

This is the type of console that you encounter in production environments. It has all the capabilities to monitor and take action, but none of the authority necessary to access the Agent s knowledge and change the way PATROL is configured..
