> #### Installing Fathom for the first time

> There are several factors to consider before you install Fathom for the first time. For example, you should analyze what you need to monitor before you begin the installation. You also need to decide where to install Fathom components.

> To prepare to install Fathom:

> 1. Determine the names and locations of the resources you need to monitor.
> The resources can include local network-based services and the following local and remote resources: database, CPU, memory, file system, disk, AppServer™, NameServer, and WebSpeedŽ Transaction server.

> 2. Determine whether you are installing Fathom against an OpenEdge10.0B or a Progress Version 9.1D product.
> If you are installing the latest release of Fathom with a Progress Version 9.1D product, you must also install a service pack before you install Fathom. See the "Progress Version 9.1D" section for details.

> 3. Determine whether to save monitoring information to the FathomTrendDatabase and, if saving the monitoring information, where to locate the FathomTrendDatabase.
> The FathomTrendDatabase stores the monitoring information that Fathom collects. During configuration, you can choose whether to save monitoring information locally, remotely, or not at all. Before installation, you should decide if you want to save this data and where you want to save it.

> Fathom automatically creates the FathomTrendDatabase if you have an OpenEdge™ Enterprise RDBMS, an OpenEdge™ Workgroup RDBMS, or an OpenEdge™ Personal database installed on the same machine where you are installing Fathom.

> If you decide to save monitoring information remotely, the remote machine must have both a database (Enterprise, Workgroup, or Personal) and Fathom installed. In other words, you cannot just copy a trending database to a remote machine. The local instance of Fathom needs to communicate with a remote instance of Fathom to use the remote trending database.

> 4. Determine how monitoring might affect system performance.
> The more resources you monitor, the more system resources Fathom uses. If you plan to monitor a large number of database servers and network services in your configuration, you might want to consider configuring additional Fathom instances, both locally and remotely.

> See the "CPU and memory requirements" section for more information.

> 5. Determine where to install Fathom.
> Based on the decisions you made in Steps 1 through 4, you can install Fathom locally on the machine with the monitored resources or on a separate or standalone machine.

> See the "Product support" section for more information.
