# Diagnose and resolve issues on DEX monitored devices

# DEX issue diagnosis and resolution agentic workflow {#ariaid-title1}

Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 4 minutes to read  
Use the Digital End-User Experience (DEX) issue diagnosis and resolution agentic workflow from the ServiceNow Otto panel to diagnose and resolve common issues on DEX monitored devices.

## DEX issue diagnosis and resolution agentic workflow capabilities {#now-assist-itsm-dex-diagnosis-resolution-workflow__section_vtk_ftd_bhc}

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 such as device health check data from 24 hours before the incident to incident time. Similar past incidents are also used. With the integration of Zoom specific diagnostics, you can diagnose Zoom call quality issues by correlating device, network, and application data.
* 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 {#now-assist-itsm-dex-diagnosis-resolution-workflow__section_u2n_k2f_bhc}

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

* ServiceNow Otto for IT Service Management (ITSM) (sn_itsm_gen_ai) plugin.
* Digital End-User Experience application. For more information, see [Install Digital End-User Experience](https://www.servicenow.com/docs/lvbU_Vdm6TylUJ9fpnKGcQ "Install the Digital End-User Experience (DEX) application (sn_dex) to start monitoring devices. Application and Device Health is included as a component of DEX.") and [Configuring Digital End-User Experience](https://www.servicenow.com/docs/gBLjP0f7TaZsn9VDcphMog "As a DEX administrator, install and configure Digital End-User Experience to monitor end-user applications, devices, and networks. Complete the core setup for Application and Device Health, and then configure the optional components and integrations that apply to your deployment.").

## Roles required to access the agentic workflow {#now-assist-itsm-dex-diagnosis-resolution-workflow__section_f11_rfv_chc}

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
{#now-assist-itsm-dex-diagnosis-resolution-workflow__ul_tnk_tfv_chc}

## Additional requirements to access the agentic workflow {#now-assist-itsm-dex-diagnosis-resolution-workflow__section_xtq_5wd_dhc}

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](https://www.servicenow.com/docs/access?context=activate-aia-use-case&version=brazil&pubname=brazil-intelligent-experiences&ft:locale=en-US).
* 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](https://www.servicenow.com/docs/Hk8h2JyyopH5HhYM3lBE0g "System requirements are the fundamental specifications and configuration needed to install and run DEX.").
* 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 ServiceNow Otto panel prompt.

## Accessing the agentic workflow {#now-assist-itsm-dex-diagnosis-resolution-workflow__section_sf3_twc_dhc}

Service desk agents can access the agentic workflow from the Service Operations Workspace by using the ServiceNow Otto panel.  
Administrators can access the agentic workflow from the AI Agent Studio.

1. Navigate to AllAI Agent StudioCreate and manage.
2. Select DEX issue diagnosis and resolution workflow.
{#now-assist-itsm-dex-diagnosis-resolution-workflow__ol_pq4_gjx_chc}

## AI agents used in the DEX issue diagnosis and resolution agentic workflow {#now-assist-itsm-dex-diagnosis-resolution-workflow__section_mwy_pf2_bhc}

In the DEX issue diagnosis and resolution agentic workflow, two AI agents are used for incident diagnosis and resolution on DEX monitored devices.{#now-assist-itsm-dex-diagnosis-resolution-workflow__table_mby_lh2_bhc__entry__2}

| 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 then requires manual investigation and resolution. |
[Table 1. AI agents and their roles listed in the order of execution in the DEX issue diagnosis and resolution agentic workflow]

## Generating an incident diagnosis and resolution plan in the Service Operations Workspace {#now-assist-itsm-dex-diagnosis-resolution-workflow__section_grv_4yp_hhc}

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 ServiceNow Otto icon to open the panel.
3. Enter a prompt that includes the phrase "diagnose and resolve". For example, Diagnose and resolve this incident.

{#now-assist-itsm-dex-diagnosis-resolution-workflow__ol_zfr_pwp_hhc}

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](https://www.servicenow.com/docs/KrnxY520latnx2Soz~UIsw "Service desk agents can diagnose and resolve issues for Digital End-User Experience (DEX) monitored devices from an incident record by using DEX diagnostics and suggested resolutions.").

2. In the Define user access screen, review or add roles that can access the use case, and then select Continue.
3. In the Define data access screen, review the user identity for the AI agent, make updates if necessary, and then select Continue.
4. In the Define trigger screen, make updates if necessary, and then select Continue. For more information about defining triggers, see [Create an agentic workflow](https://www.servicenow.com/docs/access?context=configure-use-case-ai-agents&version=brazil&pubname=brazil-intelligent-experiences&ft:locale=en-US).
5. In the Select display screen, choose where to display the agentic workflow output, and then select Save and test.
6. In the Test details screen, enter your prompt in the Task field, and then select Continue to Test Chat Response.
