The VMware Edge Network Intelligence (ENI) Self-Healing feature monitors and tracks the SD-WAN network for systemic and application performance issues across SD-WAN Edges. ENI then gathers data regarding Edge incidents and triggers remediable recommended actions through an email alert for the incidents.

This is a sample Incident Alert email with Incident details, Affected Edges, and Remediable status, sent to user on occurrence of Systemic Incidents.

Prerequisites

To use the ENI Self-Healing feature, ensure you have the following prerequisites:

  • The SD-WAN Orchestrator must be on 5.0.1 and the SD-WAN Edges must be running a minimum of 4.3.1 code.
  • Full access permission to the VMware ENI product to take a remediation action. Go to Settings > User Access and set User Role Permission to ALL.
    This screenshot shows how to configure User Role from the My Account settings.

Remediate SD-WAN Edges

Whenever the analytics engine identifies an Edge experiencing a sudden drop in application performance compared to its recent history, it creates an Edge incident and triggers a remediable recommended action through an email alert for the incident.

To take a remediation action, you can directly click the incident alert link in that email. Clicking on the incident alert will direct you to the Incidents page where you can see a list of Edge incidents (regular and Self-Healing) that are remediable.
This screenshot shows the Incident Distribution and list of Systemic Incidents that has occurred.
In the Incidents table, under the Description column click on an Edge incident. This will direct you to a Incident details page where you can take remediation actions.
Note: If a remediation action is not taken within 3 hours of the incident generation time, then the remediation action gets expired.
This screenshot provides a detailed summary about an incident along with the Edge Remediation recommendations.
  1. Click Remediate All to remediate all Edges at once. The Remediation Edges for this Incident dialog box appears.
    You can apply remediation to all Edges or selected Edges affected by the Incident.
  2. Click Apply Remediation to remediate all Edges.
  3. Click View Details to view Remediation Summary of all Edges.
  4. If you want to remediate specific Edges, click Remediate Specific Edges. The Remediation Summary dialog box appears.
    This screenshot shows the Remediation Summary of the incident and the affected Edges, and allows you to remediate all or specific Edges.
  5. Select the Edges that you want to remediate and click the Remediate button. The remediation process begins for the selected Edges and the Remediation Status column gets updated automatically based on the remediation state of the Edges.
    The following are the supported Edge remediation states:
    • Not Remediated – Remediation action is yet to be applied for the Edges
    • Pending – Remediation action applied and is in progress for the Edges
    • Applied - Remediation successfully applied for the Edges
    • Failed – Remediation action taken but failed for the Edges
    • Expired - Remediation action is not taken within 3 hours of the incident generation time, so the remediation action is expired
  6. After applying remediation, you can click View Log to view remediation logs for the Edges.
    This screenshot shows the remediation logs for the Edges.

Review Incident Details and Remediation Logs After Applying Remediation

In ENI, after applying remediations, you can review incident details and remediation logs by navigating to the Settings > Remediation log menu.

View Annotations for Remediated SD-WAN Edge Events

Once you take a remediation action, an annotation is automatically created and displayed under the Annotations section of the Network History page. To view the automated annotations generated for the remediated SD-WAN Edge events:
  1. In the ENI portal, click the Analysis tab.
  2. From the left menu, select Network History.
  3. In the Network History page, the Annotations section displays all the annotations (manual and automated) related to SD-WAN Edges.
  4. You can view remediation logs for the Edges by clicking View Log.
    This screenshot shows an annotation that is automatically created and displayed under the Annotations section of the Network History page, after you take a remediation action.

Configure Application Controls and Tracking

You can turn on and off the Tracking feature for the applications from the Admin Settings > Application Controls page. By default, tracking is turned on for all the applications.

You can also find details about which are the applications for which Remediation feature is turned on from the Application Tracking page.
