# Set performance management preferences

Preferences (general, dashboards, charts, reports, data imports, and alerts) for performance management tasks can be set.

## Prerequisites

Only a user with Administrator permission can set preferences.

For security compliance, a password must be supplied upon exporting and importing a performance settings file. If you pass the settings file to another administrator, ensure that you also provide the password.

| NOTE: An imported metrics definition overrides server settings.

## About this task

In large environments, it can be time consuming to set up and configure multiple instances. Storage systems may have similar configuration and implementations across the environment. To assist with the implementation process, you can export and import settings. The settings are saved to an .xml file. You can select the client-side directory in which the file is saved. When importing a metrics definition file, it replaces any existing metrics definition file. When you import a user runbook dashboard, any existing templates remain intact; only nonconflicting runbooks are imported.

To set performance preferences:

## Steps

2. Select Preferences > Performance.
