DEX issue diagnosis and resolution agentic workflow

Use the Digital End-User Experience (DEX) issue diagnosis and resolution agentic workflow from the Now Assist panel to diagnose and resolve common issues on DEX monitored devices.

DEX issue diagnosis and resolution agentic workflow overview

Using the DEX issue diagnosis and resolution agentic workflow:

• Get automated diagnoses for incidents on DEX monitored end-user devices. Root cause analysis is generated based on sources like device health check data from 24 hours before the incident to incident time and similar past incidents.
• Get resolution plans for detected device issues based on remedial actions and self-help instructions, past incident resolutions, and Knowledge Base articles.
• Provide approval and have the resolution summary automatically stamped to the Work notes of an incident record.

Applications required to access the agentic workflow

To access the DEX issue diagnosis and resolution agentic workflow, make sure that you install the following applications:

• Now Assist for IT Service Management (ITSM) (sn_itsm_gen_ai) plugin.
• Digital End-User Experience application. For more information, see Install Digital End-User Experience and Configuring Digital End-User Experience.

Roles required to access the agentic workflow

To use the DEX issue diagnosis and resolution agentic workflow, you must have one of the following role combinations:

• sn_dex.service_desk_user and ITIL
• sn_dex.engineer and ITIL

Additional requirements to access the agentic workflow

The DEX issue diagnosis and resolution agentic workflow provides incident diagnosis and resolution only when the following requirements are met.

• The agentic workflow must be activated. For more information, see Activate an agentic workflow template.
• The incident number must be valid.
• The incident record must be associated with a single, DEX monitored physical endpoint or device. Only one device configuration item (CI) must be configured either as the primary CI in the Configuration item field or in the Affected CIs list.
• The device associated with the incident must have a DEX compatible operating system. For more information, see DEX system requirements.
• The incident must be created within the past month. Incidents older than one month cannot be diagnosed and resolved using the agentic workflow.
• To make sure that the correct agentic workflow is initiated, include the phrase "diagnose and resolve" in your Now Assist panel prompt.

Accessing the agentic workflow

Service desk agents can access the agentic workflow from the Service Operations Workspace by using the Now Assist panel.

Administrators can access the agentic workflow from the AI Agent Studio.

1. Navigate to All > AI Agent Studio > Create and manage.
2. Select DEX issue diagnosis and resolution workflow.

AI agents used in the DEX issue diagnosis and resolution agentic workflow

In the DEX issue diagnosis and resolution agentic workflow, two AI agents are used for incident diagnosis and resolution on DEX monitored devices.

표 1. AI agents and their roles listed in the order of execution in the DEX issue diagnosis and resolution agentic workflow

AI agent	AI agent role
DEX diagnosis AI agent	Performs root cause analysis of the issue by using data from sources such as device health check metrics, device or service events, and similar past incidents. It then provides the diagnosis, highlighting affected components, data sources, and patterns. If there is insufficient or inconclusive data, the agent returns a message stating no diagnosis is possible and specifies the additional information required.
DEX resolution plan AI agent	Collects DEX resolutions that include remedial actions and self-help instructions, past incident resolutions, and Knowledge Base articles. It then generates a resolution plan with actionable steps to resolve the incident and prompts for confirmation about updating the resolution in the Work notes field of the incident record. If no resolution is found for an incident, the agent returns a message stating so. The incident would then require manual investigation and resolution.

Generating an incident diagnosis and resolution plan in the Service Operations Workspace

Service desk agents can use the agentic workflow to generate incident diagnosis and resolution plan from the Service Operations Workspace.

1. In the Service Operations Workspace, open the incident record from the Incidents list.
2. Select the Now Assist icon to open the Now Assist panel.
3. Type your prompt that includes the phrase "diagnose and resolve". For example, Diagnose and resolve this incident.

After the resolution plan is generated, you can execute it directly from the Investigation tab of the incident record. For more information, see Incident investigation with DEX.
