ServiceNow

Overview

ServiceNow is an IT service management platform for recording, tracking, and managing a company’s enterprise-level IT processes in a single location.

The Datadog ServiceNow integration is a two-way integration that allows you to:

  • Push Datadog-generated events to ServiceNow tickets, as well as manage the resolution workflow from within Datadog through IT service management (ITSM) and IT operations management (ITOM)
  • Use Datadog as a discovery mechanism for ServiceNow Configuration Management Database (CMDB) Configuration Items (CIs) with the service graph connector
  • Enrich business-specific information stored as CIs in ServiceNow CMDB with your hosts, services, and devices information from Datadog, enabling you to better understand your infrastructure usage, accelerate troubleshooting, and maximize resource utilization

Datadog integrates with the following ServiceNow tools:

  • ITOM
  • ITSM
  • CMDB

Note: The Datadog ServiceNow integration supports ServiceNow releases that are not listed as end of life.

Configure the ServiceNow tile in Datadog

  1. Navigate in Datadog to the ServiceNow integration tile on the Integrations page.
  2. Click on Add New Instance.
  3. Add the instance name, which is the subdomain of your ServiceNow domain: <INSTANCE_NAME>.service-now.com.
  4. Add the username and password for your ServiceNow instance.

Note: You can create a limited user in ServiceNow just for Datadog.

Service Graph Connector for Datadog

Service Graph Connector for Observability - Datadog can automatically populate server and database configuration items (CIs) in the CMDB for new resources discovered by Datadog. The Service Graph connector is available through the ServiceNow store.

For configuration, follow the Service Graph Connector’s guided setup instructions.

Supported CI Types:

  • Server
  • Amazon RDS

The notes below only apply if you have already configured the integration for ServiceNow ITOM/ITSM:

  • Service Graph Connector does not use the Target table and Custom table values from the configuration tile. You can save the integration with the Target table default values.
  • The same ITOM/ITSM user can be used for Service Graph Connector by granting this user the role of cmdb_import_api_admin as described in the Service Graph Connector’s guided setup instructions.

Host tagging

Enrich your Datadog hosts with ServiceNow CMDB metadata through host tagging.

To enable ingestion of host tags:

  1. Configure a Query Builder query in your ServiceNow instance that returns all of the hosts you wish to tag in Datadog.
  2. Schedule the query to execute at your desired refresh interval.
  3. Once the query has been saved in ServiceNow, go to Datadog’s ServiceNow integration tile. Select the Host Tagging in the CMDB Enrichment tab.
  4. Under Query Configuration, click the Add New Query button.
  5. Select the ServiceNow Instance and the Query from the dropdown menus.
  6. Select a value for the Hostname Column that maps your query’s root CI hostname field to Datadog’s hostname field.
  7. Select any optional field name remapping with Column Name Maps.
  8. Click Save.

Expect host tags to populate in Datadog shortly after your queries’ scheduled executions.

Troubleshooting

For host tagging to work correctly, ensure that the following are true in your system:

  • The user who created and executes the Query Builder query matches a username in your Datadog configuration. The user in ServiceNow must have the role cmdb_query_builder_read.
  • The number of results returned by your query must be less than or equal to the glide.cmdb.query.max_results_limit setting in ServiceNow. By default, the maximum number of results is 10000. To change the setting, go to Configuration -> CMDB Properties -> Query Builder Properties.
  • All CIs configured in your Query Builder query must have a 1 label. This ensures you have not created any duplicate CIs, which the parser does not support.

Limitations

  • Ingestion is limited to 100k hosts per execution.
  • Updates to hosts are throttled to a few thousand per hour. Take this limit into consideration when choosing your schedule interval.
  • Tagging does not work for Linux machines with lower case host names, because host aliases in Datadog are case sensitive.

Service tagging

Enrich your Datadog Service Catalog with ServiceNow CMDB metadata through service tagging.

With service tagging, you can populate your Datadog Service Catalog with services from your ServiceNow CMDB.

Setup

To enable ingestion of service data:

  1. Configure a Query Builder query in your ServiceNow instance that returns all of the services with which you wish to enrich the Service Catalog.
  2. Schedule the query to execute at your desired refresh interval.
  3. Once the query is saved in ServiceNow, go to Datadog’s ServiceNow integration tile. Select Service Tagging in the CMDB Enrichment tab.
  4. Under Query Configuration, click the Add New Query button.
  5. Select the ServiceNow Instance and the Query from the dropdown menus.
  6. Select a value from the Service Name Column dropdown menu. The value matches the column name on your query’s root service CI, and populates the service name in the service catalog.
  7. Configure schema mappings to pull additional metadata about your service into the service catalog. See Service definitions for details. For Datadog to accept the ingestion, each field in the mapping needs to be of the correct type to map to the service catalog service definition schema.
  8. Click Save.

Expect to see service data populated in Datadog a few minutes after your queries’ scheduled executions. To view ingestion errors, go to the Events Explorer and search for events with source:servicenow.

Troubleshooting

For service ingestion to work correctly, ensure that the following are true in your system:

  • The user who created and executes the Query Builder query matches a username in your Datadog configuration. The user in ServiceNow must have the role cmdb_query_builder_read.
  • The number of results returned by your query must be less than or equal to the glide.cmdb.query.max_results_limit setting in ServiceNow. By default, the maximum number of results is 10000. To change the setting, go to Configuration -> CMDB Properties -> Query Builder Properties.
  • All CIs configured in your Query Builder query must have a 1 label. This ensures you have not created any duplicate CIs, which the parser does not support.

Network device tagging

Add tags to your network devices in Datadog populated with data from your ServiceNow CMDB.

With device tagging, you can dynamically enrich network devices monitored by Datadog Network Device Monitoring with device metadata from your ServiceNow CMDB.

To enable ingestion of device tags:

  1. Configure a Query Builder query in your ServiceNow instance. Make sure it is returning the device IP Address.
  2. Schedule the query to execute at your desired refresh interval.
  3. If you are using a custom IP namespace in Datadog, you need to add it to ServiceNow. Create a column on the Network device CI called u_dd_device_namespace, populated by the corresponding namespace for each device. If this column is not present, the default namespace is used.
  4. Once the query is saved in ServiceNow, go to Datadog’s ServiceNow integration tile. Select Device Tagging in the CMDB Enrichment tab.
  5. Under Query Configuration, click the Add New Query button.
  6. Select the ServiceNow Instance and the Query from the dropdown menus.
  7. Select the IP Address column that maps your query’s IP Address field to Datadog’s IP Address field.
  8. Select any optional field name remappings.
  9. Click Save.

You can expect to see network device tags populated in Datadog within a few minutes after your queries’ scheduled executions. Any ingestion errors are reported through events viewable in your events explorer.

Monitor the ingestion process in the Datadog Events Explorer by scoping your search query on source:servicenow.

Screenshot showing one running ingestion

Troubleshooting

  • Verify that the user who created or is executing the querybuilder query is the same user in your Datadog configuration and has the role cmdb_query_builder_read.
  • Check that your query isn’t returning more results than your glide.cmdb.query.max_results_limit setting in Servicenow is configured to allow. Make sure all CIs configured in your querybuilder query have a ‘1’ label. Ensure you did not create any duplicate CIs, as the parser doesn’t support them.

Limitations

  • Ingestion is limited to 100k hosts per execution.
  • Network device tagging is limited to SNMP devices.
  • Updates to devices are throttled to a few thousand per hour. Take this into consideration when choosing your schedule interval.

Reference Tables

Use Reference Tables to automatically enrich logs and events with additional fields from your ServiceNow CIs. With Reference Tables, you can map sets of value fields to a primary key, such as a hostname, and automatically append these fields to all logs or events that contain the specified key.

To enable ingestion of Reference Tables:

  1. Configure a Query Builder query in your ServiceNow instance.
  2. Schedule the query to run at your desired refresh interval.
  3. Save the query.
  4. Select, Add New Query, and choose your query from the dropdown menu.
  5. In the primary key dropdown, select the column name you want to use as your primary key.
    1. Optionally, create a Processing Pipeline with this primary key to enrich and correlate logs and events.
  6. Enter a name for your reference table.
  7. Click Save.

The Reference Table will be populated with the data from the query shortly after saving.

Caveats and restrictions

  • Reference Table name must be unique.
  • Deletions and schema updates of existing tables are not supported.

ITOM and ITSM setup

Case Management integration is not supported in the site.

Incident Management integration is not supported in the site.

Templated Monitor Notifications are not supported in the site.

To use the Datadog integration for Monitors, Case Management, and Incident Management, follow these steps:

  1. Install the App
  2. Create a ServiceNow Account with correct permissions for Datadog
  3. Configure Datadog applications for use with ITOM and ITSM

  • Cases ITSM, formerly Datadog Cases ITSM
  • Legacy Monitors ITOM, formerly Datadog Monitors ITOM
  • Legacy Monitors ITSM, formerly Datadog Monitors ITSM
  • Templated Monitors ITOM
  • Templated Monitors ITSM

Create a ServiceNow Account with correct permissions for Datadog

To use the integration, create a ServiceNow user (for example, with username “datadog” or “datadog_integration”) and assign it all of the following roles:

  • x_datad_datadog.user and
  • import_set_loader and
  • import_transformer

Incident Resolution and Closure

Bidirectional syncing with Case Management is only supported for ServiceNow ITSM.

If you’d like to sync incident state for resolution, the ServiceNow user needs one of the following roles:

  • ITIL or
  • list_updater or
  • sn_incident_write

If you’d like to sync incident state for closure, the ServiceNow user needs the following role:

  • ITIL_admin

Send Monitor Notifications directly to Incident and Event Table

If you’d like to send notifications directly to the ITOM module Event table or the ITSM module Incident table, the ServiceNow user needs one of the following roles:

  • ITIL for ITSM
  • evt_mgmt_integration for ITOM

Note: Manual updates made to a ticket in ServiceNow by this ServiceNow user (“datadog” or “datadog_integration”) are not synced to Datadog.

Templated Monitor Notifications

Note: App version >= v2.6.0 required for this functionality. You also must add an instance on the Configuration page of the ServiceNow tile in Datadog before completing the below steps.

Configure Instance Priority Mapping
ServiceNow priority mapping form on the integration tile

For all templated @-handles for a particular instance, Datadog now automatically maps Monitor Priority to Impact and Urgency in ServiceNow according to this mapping.

Toggling the Use Instance Priority Mapping off disables the setting Impact and Urgency on ServiceNow records.

Configure a monitor template

The new ServiceNow integration tile

For Monitor Notifications using @servicenow-<TEMPLATE_NAME> in Datadog, use the new template creation UI in the ITOM/ITSM tab of the ServiceNow integration tile in Datadog to create a ServiceNow notification.

Note: This is only available for app versions >= 2.6.0.

Create custom ServiceNow @handle for Monitor Notifications
Monitor notification instructions on the new ServiceNow integration tile
  1. Click the + New button to create a new template.
  2. Define an @-handle Name, Instance and Target Table for the monitor notification to be delivered to. Then select one of Assignment Group, Business Service, User, or Unassigned to assign the record. The transform map defined in 2.6.0 automatically populates the incident INC record with the value you select here.

To use the new template, add @servicenow-<TEMPLATE_NAME> in a monitor description.

You can add custom fields to the payload by clicking Add Field in the Customize notification payload section.

Configure Case Management

Case Management instructions on the new ServiceNow integration tile

From the Case Management tab:

  1. Select the instance you want to configure for Case Management.
  2. Choose the table you want to send cases to: Datadog Cases ITOM or Datadog Cases ITSM. Note: No table is selected by default.
  3. Navigate to Case Management in Datadog.
  4. Select Create ServiceNow Incident.
  5. Choose the instance and optional assignment group, and then click Create.
Sync state and comments bidirectionally with Case Management

To allow edits in ServiceNow to update their associated cases in Datadog, a ServiceNow user with the x_datad_datadog.user role and admin role must configure the installation settings for the ITOM/ITSM Integration for Datadog app in ServiceNow:

  1. Navigate to the configuration settings page for the ITOM/ITSM Integration for Datadog app by clicking All in the upper-left hand corner, typing ITOM/ITSM Integration for Datadog into the filter, and clicking the Configuration link that appears in the filtered list.
  2. Choose your Datadog Data Center site.
  3. Paste a Datadog API Key, which can be found in your Organization Settings, in the API Key field.
  4. Paste a Datadog Service Account Application Key, which can be found in your Organization Settings, in the Application Key field.
  5. Check the Enabled checkbox and save your configuration changes.

After configuring the installation settings in ServiceNow, return to Datadog Case Management to configure the integration.

Note: It is important to use a Service Account Application Key for this setup rather than a user’s Application Key. A user’s Application Key is tied to the user’s account permissions. If the user’s permissions are reduced or if the user is deactivated, bidirectional syncing between ServiceNow and Datadog will stop. A Service Account Application Key is not tied to an individual user, so bidirectional sync will not be impacted by user account changes.

Configure Incident Management

After installing the app, visit the Integration Settings in the Incident App to finish setup.

Legacy Monitor Notifications

For Legacy Monitor Notifications using @servicenow-<INSTANCE_NAME> in Datadog, select the interim table to send notifications to at the bottom of the ITOM/ITSM tile titled: “Manage Legacy Monitor Notifications”.

  1. Select the instance you want to configure notifications for, then select the table that legacy monitor notifications write to.
  2. To validate the integration is set up correctly, add @servicenow-<INSTANCE_NAME> in a monitor or event notification. The raw data populates rows in the interim table and is forwarded to the ServiceNow table specified by the app.
  3. Use transform maps in ServiceNow to customize the transformation of the data sent to the interim tables.
  4. Customize the notification payload with available Datadog variables or custom strings.

Customize data for Monitor Notifications with transform maps

The Templated Monitors ITSM, Legacy Monitors ITSM, and Datadog Cases ITSM tables use a transform map to transform Datadog records into ServiceNow incidents. Similarly, the Datadog Monitors ITOM and Datadog Cases ITOM transform Datadog records into ServiceNow events.

The Templated Monitors ITOM and Templated Monitors ITSM tables use transform maps to transform Datadog records into ServiceNow events and incidents respectively. You can customize the ServiceNow events and incidents information in these tables by customizing the notification payload in the New Template UI and extend the transform maps in ServiceNow.

Note: The Datadog Cases ITOM and Datadog Cases ITSM tables similarly use transform maps; however, transform map customization is not recommended for use with Case Management given the payload for Datadog cases is not customizable.

Troubleshooting

If you’re not seeing events in your ServiceNow tables and instead have

  • An error message in your Datadog integration tile or an Error while trying to post to your ServiceNow instance notification:

    • Verify only the subdomain was used when entering your instance name.
    • Verify the user you created has the required permissions.
    • Verify the username and password are correct.

  • The integration is configured, an alert triggered, and no ticket is created:

    • Confirm that the interim table is populated. If so, the issue is with mappings and transformations. You can debug your mappings and scripts further by navigating to Transform Errors in ServiceNow.
    • Confirm that you’re working with the interim table you specified in the tile.

    The ServiceNow user needs rest_service and x_datad_datadog.user roles so that it can access the import tables. If you’re using the legacy way of sending notifications directly to either the Incident table or Event table, you need the permissions itil and evt_mgmt_integration.

If you’re seeing updates from Datadog Case Management to ServiceNow, but not seeing updates from ServiceNow to Datadog, this is expected behavior for ServiceNow ITOM. Bidirectional syncing with Case Management is only supported for ServiceNow ITSM.

Knowledge base

Templated Monitors ITXM table fields and transform maps

Datadog import host auto-flush rule

To prevent the import set table x_datad_datadog_import_host from accumulating too many rows, an auto-flush rule has been added to the Table Cleaner tool to keep only the last 24 hours of data. This configuration setting can be changed as needed by navigating to sys_auto_flush_list.do in the filter navigator and going into the rule for the x_datad_datadog_import_host table. The Age in seconds field can be updated accordingly.

Integration Configuration Settings

Auto-generate support tickets from Datadog alerts

After ServiceNow is connected to your Datadog account, alerts received can automatically create support tickets and send them to the ServiceNow ticketing queue. From there, your support team is notified of issues using the communication workflows that you have already established inside ServiceNow. Mention @servicenow in the alert message or add @servicenow to the notification list for that monitor.

ServiceNow

Use variables in ticket payload and field mappings

Variables can be used in the body of your alerts or in field mappings to ensure details from the event are included in ServiceNow. For example, you can include the title and severity in the appropriate ServiceNow field or you can include a link back to the specific incident in Datadog right from the ServiceNow ticket.

ServiceNow Variables input form
ServiceNow Variables

Incident Priority field mapping

The priority field in ServiceNow incidents is read only and can only be updated using priority lookup rules.

Define Impact and Urgency in monitors to calculate the ServiceNow incident priority.

ServiceNow Priority Field Mapping

Automate support resolution workflow

Once the monitor state returns to normal, the associated support ticket is automatically marked as “resolved”.

ServiceNow Resolved

Defining custom mappings

Click one of the tables, for example Datadog Monitors ITSM Tables, and scroll to the bottom of the record to see the link for the associated transform map.

Understanding the mapping

Click on the name of the transform map to view the record:

servicenow integration

At the top are two important fields on the Transform record - Source table and Target table:

servicenow integration

Notes:

  • The source is the import set table you selected (Datadog Monitors ITSM Tables) and the target is your actual incident table (or event table) where events are stored.
  • The field mappings are at the bottom of the record. Some basic mappings are included. This is where you select the fields to include, define the format, and select the target fields in your ServiceNow instance.

Add a new field mapping

Click New:

servicenow integration

Select the source and target fields for one to one mappings:

servicenow integration

Or, check the Use source script box and define transformations:

servicenow integration

Note: For mapping any custom fields in the Integration Tile, you can use the following mapping script for either the Datadog Monitors ITOM and Datadog Monitors ITSM Transform maps. In this example, the field my_field was defined as a custom field in the integration tile:

answer = (function transformEntry(source)
{
    var additional_info = JSON.parse(source.additional_info);
    return additional_info.custom_my_field;
})(source);

Define multiple mappings

Use Mapping Assist (under Related Links) to map several source and target fields:

servicenow integration

Validation

To validate the integration is set up correctly, add @servicenow in a monitor or event notification. The raw data populates rows in the interim table and is forwarded to the ServiceNow table specified in the mappings and transformations you created.
