An event describes a single problem or change that occurred on a resource. For example, an event
might be an SNMP trap received from a server's Integrated Lights-Out (iLO) management processor.

Each alert includes the following information about the event it reports: severity, state, description,
and urgency. You can clear alerts, assign owners to alerts, and add notes to alerts.

While alerts have an active or locked state, they contribute to a resource’s overall displayed status.
After you change their state to Cleared, they no longer affect the displayed status.

IMPORTANT:

The appliance keeps a running count of incoming alerts. At intervals of 500 alert messages, the
appliance determines if the number of alerts has reached 75,000. When it does, an auto-cleanup
occurs, which deletes alert messages until the total number is fewer than 74,200. When the
auto-cleanup runs, it first removes the oldest cleared alerts. Then it deletes the oldest alerts by
severity.

28.3.2.2 About tasks

All user- or system-initiated tasks are reported as activities:

User-initiated tasks are created when a user adds, creates, removes, updates, or deletes
resources.

Other tasks are created by processes running on the appliance, such as gathering utilization
data for a server.

The task log provides a valuable source of monitoring and troubleshooting information that you
can use to resolve an issue. You can determine the type of task performed, whether the task was
completed, when the task was completed, and who initiated the task.

The types of tasks are:

Description

Task type

A user-initiated task, such as creating, editing, or removing an enclosure group or a network set

User

An appliance-initiated task, such as updating utilization data

Appliance

A task performed in the background. This type of task is not displayed in the log.

Background

IMPORTANT:

The appliance maintains a tasks database that holds information for approximately

6 months' worth of tasks or 50,000 tasks. If the tasks database exceeds 50,000 tasks, blocks of
500 tasks are deleted until the count is fewer than 50,000. Tasks older than 6 months are removed
from the database.

The tasks database and the stored alerts database are separate.
