ServiceNow integration with FileWave

ServiceNow can be provided with device inventory information from FileWave to make the ServiceNow experience much more accurate and rewarding.  Previously, a ServiceNow portal app was required to supply this FileWave data, but as of version Orlando of ServiceNow that is no longer required, and the FileWave API can be used directly.  This guide, provided as a courtesy for a non-FileWave related system, will show you how to bring the information gathered by FileWave inventory into ServiceNow using the API.

Step-by-Step Guide

Step 1: Create Data Source

System Import Sets > Administration > Data Sources > New

  1. NAME: FileWave REST API
  2. IMPORT SET LABEL: (empty)
  3. IMPORT SET TABLE NAME: u_fw_api
  4. TYPE: REST
  5. FORMAT: JSON
  6. PATH FOR EACH ROW: /values/values
  7. DISCARD ARRAYS: √
  8. EXPAND: √
  9. DATA IN SINGLE COLUMN: (unchecked)
  10. APP: Global
  11. REQUEST ACTION: Hit the “click here” and create one (see Step 2)

Step 2: Create Request Action

  1. NAME: GET FW REST
  2. ACCESSIBLE FROM: All application scopes
  3. CATEGORY: (empty)
  4. PROTECTION: —None—
  5. DESCRIPTION: (empty)

-Request Details-

  • BUILD REQUEST: Manually
  • RESOURCES PATH: (empty)
  • HTTP METHOD: POST

The reason this is a POST is so we don't rely on an inventory query that might be changed.

Customize the fields portion as needed.

This is an example of custom fields. If the field named "asset_tag" does not exist in your system, this will cause an error.

        {
            "column": "asset_tag",
            "component": "CustomFields"
        }
  • QUERY PARAMETERS: (empty)
  • HEADERS:
    1. Name: Authorization
      Value: Your Users Application Token (FW Admin > Assistants > Manage Administrators > (select admin) > Application Tokens > (Copy the base64: e.g. aalkjdlAKJDlakjdALkdsjaldksja= )
    2. Name: Content-Type
      Value: application/json

-Request Content-

  • REQUEST TYPE: Text

-Retry Policy-

  • ENABLE RETRY POLICY: (unchecked)
  • Save
  • Test Connection
    • Test > Use “test” for “Attachment Name” > Run Test
    • Select the “Action has been executed. To view action, click here.”
    • Verify: status code of 200 (means success) 
    • Select the “(gear) GET FW REST” flow designer tab
    • Close the “Test Action” window with the X
  • Select Publish

Close this browser window/tab to return to the “New Record | Data Source | ServiceNow” window/tab

Step3, Part 2: Set Request Action

Under REQUEST ACTION, start typing the name of the Action we just created "GET FW REST" and select it from the drop-down.

Submit

Hitting 'Submit' will redirect you back to the Data Source list. Select the one we just made, FileWave REST API and select "Load All Records" under Related Links

Once the test has completed, go back to FileWave REST API's Data Source page and continue to next step.

Step 3, Part 3: Generate Data Transform

Generate Transform(s)

— MAKING TRANSFORMS ––

On the FileWave REST API page, scroll down to the “Transforms” tab and select “New”

  • NAME: FW API Map
  • SOURCE TABLE: (should auto fill the u_fw_api table)
  • ACTIVE: √
  • RUN BUSINESS RULES: √
  • ENFORCE MANDATORY FIELDS: No
  • COPY EMPTY FIELDS: (unchecked)
  • CREATE NEW RECORD ON EMPTY COALESCE FIELDS: √
  • APPLICATION: Global (input disabled)
  • CREATED: Will auto-generate with Date/Time stamp when saved (input disabled)
  • TARGET TABLE: Computer [cmdb_ci_computer]
  • ORDER: 100
  • RUN SCRIPT: (unchecked)

Table Transform Map

Select “Mapping Assist” under Related Links

You should be able to map a lot of the client's information, for example...

FileWave

ServiceNow

operatingsystem_type

Operating System

client_cpu_count

cpu_count

client_current_ip_address

ip_address

client_ram_size

ram

customfields_asset_tag

asset_tag

client_total_disk_space

disk_space

operatingsystem_version

os_version

client_cpu_speed

cpu_speed

client_filewave_client_name

client_serial_number

serial_number

...

  

Mapping Assist


You can make more maps, like this example for location data:

Scroll down to the “Transforms” tab and select “New”

  • NAME: FW Location Map
  • SOURCE TABLE: (should auto fill the u_fw_api table)
  • ACTIVE: √
  • RUN BUSINESS RULES: √
  • ENFORCE MANDATORY FIELDS: No
  • COPY EMPTY FIELDS: (unchecked)
  • CREATE NEW RECORD ON EMPTY COALESCE FIELDS: √
  • APPLICATION: Global (disabled)
  • CREATED: (disabled)
  • TARGET TABLE: Location [cmn_location]
  • ORDER: 100
  • RUN SCRIPT: (unchecked)

Select “Mapping Assist”

FileWave

ServiceNow

geolocation_latitude

latitude

geolocation_longitude

longitude

client_filewave_client_name

Name

Once you're finished, save your data, update the Table Transform Map form and continue to next steps.

Part 4: Schedule the Job
