## Introduction

#### What is Guardian?

Guardian is a diagnostic tool for identifying potential problems in your environment before they occur, and provides specific instructions for resolving them. Guardian is like having the entire BEA Customer Support Team scrutinize your domain and immediately present their findings and recommendations to you, at your convenience.

#### How do you use it?

First, activate one or more Domain s in Guardian. A domain is a logically related group of WebLogic Server resources that you manage as a unit. You can also organize multiple domains into Domain Groups. Then, select one or more domains, select a Signature Bundle, and launch an Evaluation. Guardian then proceeds to evaluate the Signature Bundle against the specified domain(s), and generates a detailed report of potential issues and their remedies. You can then review the report and decide how to proceed.

#### Where can I run it?

Guardian can run on Windows or Linux systems that have Java Version 5 or higher installed. Guardian can evaluate any platform based on WebLogic Server version 8.1 through 10.3, regardless of the operating system on which it is running.
