> #### Defining monitoring and trending options for file systems and disks

> Fathom can create resource monitor and trending options for all file systems and disks on a system where Fathom Management is installed.

> As shown in Figure 5–9, you can specify whether you want Fathom to monitor only those file systems and disks used by OpenEdge databases, or all file systems and disks. You can also choose whether or not Fathom should collect and store trend data on the file systems and disks. If you prefer, you can opt not to set up monitors for file systems and disks at all.

> Figure 5–9: Defining monitors for file systems and disks

> These file system and disk resource monitors are created with default settings, helping you to expedite the resource monitoring setup activities.

> ##### Monitoring and trending considerations

> Consider the following before you add monitors for file systems and disks for your OpenEdge databases:

> - If a file system monitor or resource does not already exist, a new file system resource or monitor is configured. The monitor or trend process is enabled for each file system that is accessed by a managed database or any of its extents.
> - If a disk monitor or resource does not exist, a new disk resource or monitor is added. The monitor or trend process is enabled for each disk on the system that is accessed by a managed database or any of its extents.

> Choose one of the following options to define monitors for file systems and disks:

> - Select Do not define any file system or disk monitors to bypass any monitoring and trending options.
> - Select Define monitors for file systems and disks used by Progress databases to add only monitors for file systems and disks.
> - Select Define monitors for file systems and disks used by Progress databases and collect and store trend data to add monitoring and trending activities for file systems and disks used by your OpenEdge databases.
> - Select Define monitors for all file systems and disks to define monitors for all file systems and disks, not just those used by OpenEdge databases.
> - Select Define monitors for all file systems and disks and collect and store trend data to add monitoring and trending activities for all file systems and disks, not just those used by your OpenEdge databases.
