This topic provides information on the different types of alerts in VMware Aria Operations, how to access them, and how to view more information about these alerts.
Types of Alerts
Alerts in VMware Aria Operations are of three types. The alert type determines the severity of the problem.
- Health Alerts
- The health alert list is all the generated alerts that are configured to affect the health of your environment and require immediate attention. You use the health alert list to evaluate, prioritize, and immediately begin resolving the problems.
- Risk Alerts
- The risk alerts list is all the generated alerts that are configured to indicate risk in your environment. Address risk alerts in the near future, before the triggering symptoms that generated the alert negatively affect the health of your environment.
- Efficiency Alerts
- The efficiency alerts list is all the generated alerts that are configured to indicate problems with the efficient use of your monitored objects in your environment. Address efficiency alerts to reclaim wasted space or to improve the performance of objects in your environment.
Accessing Alerts VMware Aria Operations
The All Alerts or the Administrative Alerts page provides the list of all the alerts generated in VMware Aria Operations. Use the alert list to determine the state of your environment and to begin resolving problems.
Where You Find the All Alerts Page
From the left menu, click .
Where You Find the Administrative Alerts Page
As an admin, you can view the administrative alerts by clicking the warning icon next to the Alerts menu or from the left menu, click and then click the Administrative Alerts tab. You can view the Administrative Alerts page, only if you are a global admin user or if you have administrative privileges assigned to you.
How the All Alerts and Administrative Alerts Pages Work
By default, only active alerts are initially listed, and the alerts are grouped by Time. Review and manage the alerts in the list using the toolbar options. Select multiple rows in the list using Shift+click, Control+click.
To see the alert details, click the alert name. The alert details appear on the right, including the symptoms triggered by the alert. The system offers recommendations for addressing the alert and link to run the recommendation. A Run Action button may appear in the details. Hover over the button to learn what recommendation is performed if you click the button. Alternatively, you can view the Run button and the Suggested Fix in the Alerts data grid. You can filter by alerts that have the Run option activated and perform the recommended task to address the alert from the Alerts data grid. Click the small box on the lower left of the alert list to include the Suggested Fix and Run columns in the data grid.
Click the name of the object on which the alert was generated to see the object details, and access additional information relating to metrics and events.
If you migrated alerts from a previous version of VMware Aria Operations , the alerts are listed with a cancelled status and alert details are not available.
All Alerts and Administrative Alerts Options
The alert options include toolbar and data grid options. Use the toolbar options to sort the alert list and to cancel, suspend, or manage ownership. Use the data grid to view the alerts and alert details.
Select an alert from the list to activate the Actions menu:
| Option | Description |
|---|---|
| Cancel Alert | Cancels the selected alerts. If you configure the alert list to display only active alerts, the canceled alert is removed from the list. Cancel alerts when you do not need to address them. Canceling an alert does not cancel the underlying condition that generated it. Canceling alerts is effective if the alert is triggered by fault and event symptoms, because these symptoms are triggered again only if subsequent faults or events occur on the monitored objects. If the alert was generated based on metric or property symptoms, the alert is canceled only until the next collection and analysis cycle. If the violating values are still present, the alert is generated again. |
| Delete Canceled Alerts | Delete cancelled (inactive) alerts by doing a group selection or by individually selecting alerts. The option is deactivated for active alerts. |
| Suspend | Suspend an alert for a specified number of minutes. You suspend alerts when you are investigating an alert and do not want the alert to affect the health, risk, or efficiency of the object while you are working. If the problem persists after the elapsed time, the alert is reactivated and it will again affect the health, risk, or efficiency of the object. The user who suspends the alert becomes the assigned owner. |
| Assign to | Assign the alert to a user. You can search for a specific username and click Save to assign the alert to the selected user. |
| Take Ownership | As the current user, you make yourself the owner of the alert. You can only take ownership of an alert, you cannot assign ownership. |
| Release Ownership | Alert is released from all ownership. |
| Go to Alert Definition | Switches to the Alert Definitions page, with the definition for the previously selected alert displayed. |
| Deactivate... | Provides two options to deactivate the alert:
Note: To activate the Deactivate option, select
Definition from the
Group By drop-down list, and click on the name of the Alert Definition Group.
|
| Open an external application | Actions you can run on the selected object. For example, Open Virtual Machine in vSphere Client. |
| Option | Description |
|---|---|
| None | Alerts are not sorted into specific groupings. |
| Time | Group alerts by time triggered. This is the default option. You can also group by 1 hour, 4 hours, Today and Yesterday, days of current week, Last week and Older. |
| Criticality | Group alerts by criticality. Values are, from the least critical: Info/Warning/Immediate/Critical. See also Criticality in the "All Alerts Data Grid Options" table, below. |
| Definition | Group alerts by definition, that is, group like alerts together. |
| Object Type | Group alerts by the type of object that triggered the alert. For example, group alerts on hosts together. |
| Scope | Group alerts by scope. You can search for alerts within the selected scope. |
| Quick Filters | Descriptions |
|---|---|
| Filtering options | Limit the list of alerts to those matching the filters you choose. For example, you might have chosen the Time option in the Group By menu. Now you can choose Status -> Active in the Quick Filters menu, and the All Alerts/Administrative Alerts page displays only the active alerts, ordered by the time they were triggered. |

| Impact | Alert badge affected by the alert. The affected badge, health, risk, or efficiency, indicates the level of urgency for the identified problem. |
| Alert Subtype | Additional information about the type of alert that is triggered on a selected object. This helps you categorize the alerts in a detailed level other than Alert Type, so that you can assign certain types of alerts to specific system administrators. For example, Availability, Performance, Capacity, Compliance, and Configuration. |
| Status | Current state of the alert. Possible values include Active or Canceled. |
| Criticality | The level of importance of the alert in your environment. The level is based on the level assigned when the alert definition was created, or on the highest symptom criticality, if the assigned level was Symptom Based.
The possible values include:
|
| Triggered On | Name of the object for which the alert was generated, and the object type, which appears in a tooltip when you hover the mouse over the object name. Click the object name to view the object details tabs where you can begin to investigate any additional problems with the object. |
| Control State |
State of user interaction with the alert. Possible values include:
|
| Object Type | Type of object on which the alert was generated. |
| Created On | Date and time when the alert was generated. |
| Updated On | Date and time when the alert was last modified.
An alert is updated whenever one of the following changes occurs:
|
| Canceled On |
Date and time when the alert canceled for one of the following reasons:
|
| Action | Choose Yes to filter based on alerts that have the Run option activated. Choose No to filter based on alerts that have the Run option deactivated. |
The Alerts data grid provides the list of generated alerts used to resolve problems in your environment. An arrow in each column heading orders the list in ascending or descending order.

-
The Related Scope displayed on the right, shows the objects that are one level above and one level below the object on which the alert was triggered. This topology is fixed. You cannot change the scope in the Related Alerts tab.
On the right, you can see the following:- If the same alert was triggered on the object in the past 30 days. This helps you understand if this is a recurring problem or something new.
- If the same alert was triggered on other peers in the same environment, in the past 30 days. This helps you do a quick peer analysis to understand if others are impacted with the same problem.
- All the alerts triggered in the current topology. This helps you investigate if there are other alerts upstream or downstream in the environment which are impacting the health of the object.
- Potential Evidence Tab
-
See the Potential Evidence tab for potential evidences around the problem, and to arrive at the root cause. This tab displays events, property changes, and anomalous metrics potentially relevant to the alert. The time range and the scope are fixed. To modify the scope or the time range and investigate further, click Launch Workbench. This runs the troubleshooting workbench.
The time range that is displayed in the potential evidence tab is two hours and thirty minutes before the alert was triggered. VMware Aria Operations looks for potential evidences in this time range.
Intelligent Alerts
Every enterprise could have five or more monitoring tools that monitor various aspects of their data center operations around the clock. This could cause an alert flooding situation where multiple alerts are generated by a single monitoring tool or multiple tools for the same problem. As a result, IT administrators must sift through thousands of alerts to filter out the noise and focus on key issues, thus, increasing the sheer volume of the alerts and posing an alert storm or alert noise resulting in teams being unable to identify the most critical alerts. Alert flooding happens because monitoring tools lack the intelligence to understand that all alerts depict the same problem.
Machine Learning (ML) helps automate the management of complex systems that contain thousands of objects like VMs, Hosts, and Datastores, through monitoring millions of metrics, huge volumes of logs, and application traces, to capture a high-resolution image of the entire stack.
VMware Aria Operations through intelligent alert clustering helps eliminate business downtime that happens because of a lack of faster troubleshooting abilities and solving critical problems over multiple objects.
Where You Find the Intelligent Alerts Tab
From the left menu, click , and then, click the Intelligent Alerts tab.
How Intelligent Alert Clustering Works
Intelligent alerts, also known as alert clusters in VMware Aria Operations, groups related alerts together based on their creation time and their topology distance. This approach provides a more organized and efficient method for troubleshooting, compared to dealing with individual alerts arising from the same underlying issue. Alerts clustering is done based on DBScan algorithm. DBScan (Density-Based Spatial Clustering of Applications with Noise) is an unsupervised clustering Machine Learning algorithm that attempts to group data points closely packed into artificial clusters. In the context of VMware Aria Operations, DBScan has been tailored into a streaming algorithm with specific parameters configured such as minimum points is set to five, time difference is set to fifteen minutes, and topology distance is set to one, for considering only direct children and parents. Two main views, Intelligent alert lifetime and Objects topology, are provided for alert cluster troubleshooting.
