## Monitoring Overview

As an administrator, you have several options for monitoring the system. When you are at the same site as the system, you can review the events on the Sun Web console, which receives them from a provider, such as Sun StorEdge Enterprise Storage Manager. When you are at a different site from the system, you can still monitor the system as follows:

- You can receive alerts in an email message.
- You can use the system's Sun StorEdge Remote Response feature to send alerts to Sun Microsystem's Network Storage Command Center (NSCC). Remote monitoring allows a system to "phone home" or "call home" to report its status or any alerts. This feature reports telemetry of system performance data to Sun for knowledge-based analysis.
- You can configure alerts to be sent to diagnostic software that is running on a management host on your network. A trial version of Sun StorEdge Enterprise Storage Manager is included in the system. Its Diagnostic Reporter component collects alerts from multiple storage devices, including one or more Sun StorEdge 6920 systems, on the same network.

Events and alerts are related to each other and to alarms:

- An event is a notification that contains information about something that happened on a device. There are many types of events, and each type describes a separate occurrence.
- An alert is a subtype of an event that requires user intervention. The term actionable event often describes an alert.
- An alarm is a warning of an existing or approaching alert.

The monitoring software records alerts and notifications. You can monitor events and alerts by displaying the log file. You can also set up event notification so that notifications of actionable events are sent to your email address or pager.

When you receive an alert or a notification, use the following procedure to investigate the problem:

1. Go to the Sun Web Console page and click Storage Automated Diagnostic Environment.
2. Click Service > Service Advisor.

The Service Advisor page provides information about the probable cause and suggests the appropriate actions.

You can monitor the system through LEDs, log files, and error messages.
