ServiceNow

Collect topology data from ServiceNow

Overview

The ServiceNow StackPack allows near real time synchronization between ServiceNow and StackState. When the ServiceNow Agent integration is enabled, configuration items (CIs) and their dependencies from the ServiceNow CMDB will be added to the StackState topology as components and relations.

Data flow
  • Agent V2 connects to the configured ServiceNow API.

  • CIs and dependencies for the configured CI types are retrieved from the ServiceNow CMDB (default all).

  • Agent V2 pushes retrieved data to StackState.

  • StackState translates incoming CIs and dependencies into topology components and relations.

Setup

Prerequisites

To set up the StackState ServiceNow integration, you need to have:

Install

Install the ServiceNow StackPack from the StackState UI StackPacks > Integrations screen. You will need to provide the following parameters:

  • ServiceNow Instance ID: the ServiceNow instance ID from which topology will be collected. For example, if the ServiceNow Instance URL is https://dev102222.service-now.com, then the ServiceNow Instance ID will be dev102222.

Configure

To enable the ServiceNow check and begin collecting data from ServiceNow, add the following configuration to StackState Agent V2:

  1. Edit the Agent integration configuration file /etc/sts-agent/conf.d/servicenow.d/conf.yaml to include details of your ServiceNow instance:

    • url - the REST API url, uses HTTPS protocol for communication.

    • user - a ServiceNow user with access to the required ServiceNow API endopints​

    • password - use secrets management to store passwords outside of the configuration file.

      init_config:
      # Any global configurable parameters should be added here
      default_timeout: 10
      min_collection_interval: 5
      ​
      instances:
      - url: "https://<instance_ID>.service-now.com"
      basic_auth:
      user: <instance_username>
      password: <instance_password>
      batch_size: 100 # the maximum number of records to be returned
  2. Optional: Specify the CI types that should be retrieved (default all).

  3. ​Restart the StackState Agent(s) to apply the configuration changes.

  4. Once the Agent has restarted, wait for the Agent to collect data from ServiceNow and send it to StackState.

Filter retrieved CI types

By default, all available ServiceNow CI types will be sent to StackState. If you prefer to work with a specific set of resource types, you can configure the Agent integration to filter the CI types it retrieves:

  1. Edit the Agent integration configuration file /etc/sts-agent/conf.d/servicenow.d/conf.yaml.

    • A subset of the available CI types is listed and commented out.

  2. Uncomment the line include_resource_types and the CI types you would like to send to StackState. You can add any valid ServiceNow CI type to the include_resource_types list, however, components from resource types that you have added will appear on the Uncategorized layer of a StackState view.

    instances:
    - url: "https://<instance_ID>.service-now.com"
    user: <instance_username>
    password: <instance_password>
    batch_size: 100
    # include_resource_types: # optional and by default includes all resource types(sys Class Names)

REST API endpoints

The ServiceNow user configured in StackState Agent V2 must have access to read the ServiceNow TABLE API. The specific table names and endpoints used in the StackState integration are described below. All named REST API endpoints use the HTTPS protocol for communication.

Table Name

REST API Endpoint

cmdb_ci

/api/now/table/cmdb_ci

cmdb_rel_type

/api/now/table/cmdb_rel_type

cmdb_rel_ci

/api/now/table/cmdb_rel_ci

Refer to the ServiceNow product documentation for details on how to configure a ServiceNow user and assign roles.

When the ServiceNow integration is enabled, the following ServiceNow specific views are available in StackState:

  • ServiceNow Applications

  • ServiceNow Business Processes

  • ServiceNow Discovered

  • ServiceNow Infrastructure & Network

  • ServiceNow Machines & Load balancers

Open source

The code for the StackState ServiceNow check is open source and available on GitHub at: https://github.com/StackVista/stackstate-agent-integrations/tree/master/servicenow​

To uninstall the ServiceNow StackPack and disable the ServiceNow check:

  1. Go to the StackState UI StackPacks > Integrations > ServiceNow screen and click UNINSTALL.

    • All ServiceNow specific configuration will be removed from StackState.

  2. Remove or rename the Agent integration configuration file, for example:

    mv servicenow.d/conf.yaml servicenow.d/conf.yaml.bak
  3. ​Restart the StackState Agent(s) to apply the configuration changes.
