Introducing Key Features and Concepts 1 vCenter Operations Managerprovides monitoring functionality for your virtual environment. Understanding important features and concepts of vCenter Operations Manager helps you use the product effectively.
VMware vCenter Operations Manager Getting Started Guide Main Concepts of vCenter Operations Manager vCenter Operations Manager uses certain concepts that can help you understand the product, its interface, and how to use it. Attributes and Metrics vCenter Operations Manager collects several kinds of data for each inventory object. For example, for a virtual machine, vCenter Operations Manager might receive data about free disk space, CPU load, and available memory.
Chapter 1 Introducing Key Features and Concepts Alerts and Faults vCenter Operations Manager generates alerts when events occur on the monitored objects, when data analysis indicates deviations from normal metric values, or when a problem occurs with one of the vCenter Operations Manager components. Events that the vCenter Serverpublishes are the main source for faults.
VMware vCenter Operations Manager Getting Started Guide Table 1-1. Major Metric Concepts (Continued) Metric Description Limit Maximum amount that an object can obtain from a resource. The limit sets the upper bound for CPU, memory, or disk I/O resources that you allocate and configure in vCenter Server. The usage amount is less than or equal to the limit amount. The demand amount can be greater than the limit amount. The limit amount is less than or equal to the provisioned amount.
Beginning to Monitor the Virtual Environment 2 To use vCenter Operations Manager to monitor your virtual environment, you must understand the icons, badges, and key metric concepts used in the product.

Working with Faults and Alerts 6 vCenter Operations Manager generates alerts when events occur on the monitored objects, when data analysis indicates deviations from normal metric values, or when a problem occurs with one of the vCenter Operations Manager components. Events that the vCenter Serverpublishes are the main source for faults.
VMware vCenter Operations Manager Getting Started Guide Device-Specific Faults Faults occur on a resource, but at times can represent a problem that is more specific. For example, a vSphere host can lose network connectivity, but the problem is also specific to a NIC within the host. Another example is when a vSphere host loses connectivity to a storage device. The fault manifests itself on the host, but it is also specific to the storage device to which the connectivity was lost.
Chapter 6 Working with Faults and Alerts Types of Alerts vCenter Operations Manager generates several types of alerts. Double-click alerts in the list to view the alert details. Badge Score Alerts Badge score alerts are triggered when a badge changes its color. Badge colors change based on the hard thresholds that you set in the Configuration dialog box. Alerts can be triggered for the Workflow, Anomalies, Time Remaining, Capacity Remaining, Stress, Waste, and Density badges.
VMware vCenter Operations Manager Getting Started Guide External Alert Notifications An administrator can configure vCenter Operations Manager to send email and SNMP notifications when an alert triggers. SMTP and SNMP notifications are set on the vCenter Operations Manager Administration Web page. The URL format is https://VM-IP/admin/, where VM-IP is the IP address or fully qualified host name of the UI VM virtual machine that is part of the vCenter Operations Manager virtual appliance.
Chapter 6 Working with Faults and Alerts 3 In the Alerts list, filter the list by the Capacity Remaining badge to view alerts that address capacity. When you double-click an alert, vCenter Operations Manager opens a pop-up window displaying the alert details. What to do next To find aggregate information for used and total capacity and capacity trends, click the Views tab under the Planning tab and select the Capacity badge.
VMware vCenter Operations Manager Getting Started Guide Take Ownership of an Alert Users can take ownership of alerts in the Alerts list. Owning an alert means that you are responsible for taking the necessary remediation actions, and prevents other users from suspending or suppressing the alert. This can reduce overlapping efforts when multiple operators manage alerts. The user names of alert owners appear in the User Name column of the Alerts list.
Chapter 6 Working with Faults and Alerts Prerequisites Verify that you are logged in to a vSphere Client, and vCenter Operations Manager is open. NOTE You do not need administrative privileges to suppress or suspend alerts. Procedure 1 Click the Alerts tab. 2 In the Alerts list, click the alert you want to suppress. 3 (Optional) To select multiple alerts in the list, press the Shift or Control key and click to select the alerts. 4 5 Click the Suppress button .
VMware vCenter Operations Manager Getting Started Guide Cancel a Fault Alert You can deactivate fault alerts if they are no longer valid. Fault alerts are triggered by events that are retrieved from the vCenter Server. All the fault events that appear in vCenter Operations Manager have associated remediation events that will clear the fault badge score and the associated alert.
Chapter 6 Working with Faults and Alerts 2 Select the fault alert to be cancelled. You can use Shift+click to multi-select alerts. 3 Click Cancel fault alerts on the alerts toolbar above the alerts list. Canceling a fault manually has the same effect as a remediation event: the badge score is restored and the associated alert is no longer active.
