Key Features

Anomaly Detection Tab: Displays Discovery schedules with detected anomalies categorized by severity—Critical (failed runs), Major (low CI discovery rate), and Minor (long run time or high error count). Anomaly detection requires enabling and a minimum of five CIs to trigger. Visual indicators summarize metrics such as failed schedules, low CI discovery rates, increased errors, and long run times. Filters by schedule name, severity, and anomaly type help prioritize actions. Administrators can clear anomalies or adjust detection settings directly from this tab.
Diagnostics Tab: Lists all errors from discovery processes, allowing creation or editing of error tasks for tracking resolution. Filters and sorting options include schedule, error name, code, priority, and error categories (e.g., CMDB, Network). Selecting error counts links to detailed error stats pages with instructions and associated knowledge base articles. Action menus provide options to ignore errors, retry discovery, exclude IPs globally, or check Shazzam port status.
Case Management Tab: Offers an overview of error task statuses with Kanban and List views. Administrators can create new tasks tied to errors and filter tasks by schedule or search by task name.
Support Tools Tab: Contains tools to assist with troubleshooting and investigation specific to Discovery Admin Workspace.
Logs Tab: Provides access to ECC Queue and Discovery Logs, allowing filtering, detailed views, and export options to facilitate error diagnosis.
Ignored Errors Tab: Maintains a rolling 30-day record of ignored errors, enabling administrators to restore any ignored error back to active diagnostics if needed.
Virtual Agent Chat: Embedded in each tab, this chatbot aids in retrieving diagnostic information and troubleshooting. It supports functions like MID Server health validation (pre-upgrade checks, status, mutual authentication), pattern synchronization validation, retrieving MID Server settings, evaluating discovery performance metrics, and accessing various logs. Activation requires enabling the sndiscoworkspace.visibilitydiagnosticutility property.

Key features

Anomaly detection tab

Displays all the Discovery schedules with anomalies detected in a certain time period. You can configure this time scale on the Settings page.

Important:

This tab only displays anomalies when anomaly detection is enabled. Starting with v1.11.0, anomaly detection requires a minimum of five CIs to trigger. For more information, see the https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB2601541 article in the Now Support Knowledge Base.n the Now Support Knowledge Base.

Select the More options icon (), then select Refresh to refresh the data for each visualization in this section.

Table 1. Data visualizations
Report title	Type	Description
Schedules with anomalies	Indicator	Number of Discovery schedules with anomalies detected over a certain time period. Schedules are categorized as the following: Critical anomalies: Failed to run. Major anomalies: Have a low CI discovery rate. Minor anomalies: Have a long run time or a high error count.
Failed schedules	Indicator	Number of Discovery schedules that failed to run.
Low CI discovery rate	Indicator	Number of Discovery schedules that have a low CI discovery rate. Note: The threshold for the CI discovery rate can be configured on the Settings page.
Increased error count	Indicator	Number of Discovery schedules that have an increased error count. Note: The threshold for the error count can be configured on the Settings page.
Long run time	Indicator	Number of Discovery schedules that had a long run time. Note: The threshold for the run time can be configured on the Settings page.

Selecting any of the indicators filters the table to reflect the schedules represented in the data count. For each entry in the table, you can view details around the type and severity of anomalies.

The Actions drop-down menu provides a direct shortcut to the Settings page for configuring anomaly detection. Additionally, the menu includes a Clear all anomalies option so that administrators can quickly remove records in the Discovery Schedule Anomaly [discovery_schedule_anomaly] and Discovery Schedule Anomaly Metrics [discovery_schedule_anomaly_metrics] tables.

Use the Filter by options to prioritize and address anomalies. Filter Discovery schedules by name using the Schedules drop-down menu. Additionally, you can prioritize the results with the Severity drop-down menu, which includes options such as Critical, Major, and Minor. Use the Anomaly type drop-down menu to quickly view schedules with the same anomaly. Available options include Failed schedule, Low CI discovery rate, Increased error count, and Long run time.

Diagnostics tab

Displays all errors from every discovery. For each entry in the Discovery errors table, you can either create an error task or ignore the error using the Create task and Ignore buttons. If an entry already has an error task, it displays the Edit task button along with the task's name and priority.

Use the Filter by options to prioritize and address errors. You can filter by Discovery schedule with the Schedule drop-down menu, or search for the name of the error with the Search bar. Use the Sort drop-down menu to organize the results by Code, Priority, and Total Errors, in either ascending or descending order.

The error records can also be filtered with the Filter by and Has task drop-down menus. In the Filter menu, you can choose to show only errors related to CMDB, Configuration, Credentials, Internal, or Network. Multiple categories can be selected at the same time. The Has task menu shows either all error records, error records that have a task, or error records without a task.

For each entry in the Discovery errors table, the Total Errors number can be selected to navigate to the Error Stats Page. This page displays information on the error and provides Instructions, and an associated Knowledge Base article when available. If the error has an associated task, the task number is displayed in the header and can be accessed by selecting the button. The Action drop-down menu provides suggested actions based on the type of error. In the Errors table, the Action on selected drop-down menu can ignore errors for individual IP addresses, retry their discovery, add them to the global exclusion list, or check their Shazzam port status.

Case Management tab

Provides an overview of the statuses of error tasks. You can select each task to navigate to its detailed record. New tasks can be created and associated with existing errors using the Create Task button. You can filter by Discovery schedule with the Schedule drop-down menu, or search for the name of the error task with the Search bar. Use the Kanban Board View and List View to change the display style.

Support tools

The Support tools tab provides tools to investigate and troubleshoot your instance. For a full list of the tools available on this tab, see Discovery Admin Workspace support tools.

Logs

Keeps a record of all errors ignored in the last 30 days. Errors older than 30 days are deleted. You can add an error back to the Discovery errors table using the Undo ignore button.

Virtual agent chat

The Diagnostics page features a virtual agent chatbot in each tab. This chatbot can help retrieve diagnostic information for troubleshooting issues with Discovery. You can either enter a specific request or select Show me everything to view all available options.

Important:

The virtual agent only displays when the sn_disco_workspace.visibility_diagnostic_utility.enabled property is set to true.

Selecting the Discovery & MID Server Health Validation prompt provides the following options:

MID Server Pre-Upgrade Check: Enables you to run on-demand tests on the MID Server before upgrading. It identifies issues that might stop the upgrade process and provides a log to help resolve any issues found.
MID Server Status Validation: Validates that the MID Server user is active and is part of the mid_server group, and checks for basic user authentication errors.
MID Server Mutual Authentication: Enables you to select a specific user and verify that the user has an active, non-expired certificate.
Pattern Synchronization Validation: Verifies that a pattern and its related libraries are synchronized with the given MID Server and determines if they’re custom.

Selecting the MID Server Settings Retriever prompt enables you to retrieve settings from the available MID Servers. If there’s more than one MID Server, the agent provides a list of MID Servers to choose from. Then, you can download the configuration file and analyze the configuration values for the selected MID Server.

Selecting the Discovery Performance Metrics prompt examines the ECC Queue to gather performance metrics for a discovery status, providing the following information:

Average wait times for processing ECC Queue inputs.
Average wait times for the MID Server to process ECC Queue outputs.
Information about the probes or sensors that took the longest time to complete their tasks.

Selecting the Retrieve Logs prompt enables you to access Pattern Logs, Discovery Logs, or Node Logs. Pattern logs can be retrieved using the ECC Queue output ID or the Managed IP address and pattern name. Discovery logs can be accessed by log status or ECC Queue input, and node logs by transaction ID or ECC Queue input.
