CA-NIM EVENT Customization, Field Mapping problem.

Products

• OPS/MVS Event Management & Automation

Issue/Introduction

Tried to define new field mappings in NIM EVENT Customization. The field(s) can be defined but I am not able to use them. The below process was used.

• Log in to NIM
• Select Customizations
• Change pulled down CI Type to EVENT
• Define NEW field mappings (bottom of the screen)
e.g. appid = u_app_id
metricvalue = u_metric_value
eventclass = event_class

Add and Save the configuration.
If the above user (U) fields are not available use any that are or try any known ServiceNOW field.
Using CA-NIM API Explorer POST EVENT, try to send a package to CA-NIM (JSON) using the new fields.

Receiving errors like:
Unrecognized field "appid" - - - not marked as ignorable

On my end it appears the new fields are not recognized and am not able to use it. 

Environment

OPS/MVS integration to CA-NIM then ServiceNOW

Cause

Incorrect Payload provided to CA-NIM.

Resolution

Level 2 provided correct syntax to receive Payload which is:

    <customProperties>
      <name>SnowCustomField</name>
      <value>Test Custom Value</value>
    </customProperties>
