HP OneView - Manual (Page 174)

You can assign alerts to the appropriate administrator for their timely resolution. When issues are
investigated and resolved, you can clear them so they no longer require your attention.
You can annotate alert messages to keep an historical record of issues and their resolutions, or
you can note a decision that affected the alert resolution.
24.3.1.1 Activity types: alerts and tasks
24.3.1.1.1 About alerts
The appliance uses alert messages to report issues with the resources it manages. An alert represents
an event for a given resource that typically originates from the resource.
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 has a severity, a state, a description, and an urgency. A user with the proper privileges
can clear alerts, assign owners to alerts, and add notes to alerts.
Resources generate alerts to notify you that some action is required.
Alerts contribute to a resource's overall displayed status, but only if the alerts are still active (that
is, you have not changed their state to Cleared).
IMPORTANT:
The appliance stores up to 75,000 alert messages. Every 500 alert messages, the appliance
determines if the maximum of 75,000 was exceeded. If it has, an auto-cleanup occurs. The
auto-cleanup deletes alert messages in the following order until the total number is fewer than
74,200:
•
Oldest cleared alerts
•
Oldest alerts by severity
These stored alert messages differ from the database of stored tasks.
24.3.1.1.2 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
