HTTP API Overview
This document provides various examples of connecting to an IBM Netcool/OMNIbus API from edgeCore. It is written against Netcool Version 8.1.
Please see the following link as needed for Netcool HTTP API documentation:

HTTP API Authentication
Access to the HTTP API is protected by Basic Authentication.
Example Connection Configuration
edgeCore connects to the Netcool HTTP API using a Web Data Connection. An example Connection Configuration is presented below:
| Connection Property | Example |
|---|---|
| Connection Name | NCOM HTTP API |
| Destination | https://<NetcoolHttpApiEndpoint> |
| SSO Handler | Basic Auth |
| SSO Credentials | Username: <netcool user> Password: <netcool password> |
Example Feed Configurations
edgeCore makes requests to the Netcool HTTP API using the JSON Feed. Below are defaults for all Netcool Feed configuration properties, unless otherwise specified:
| Default Feed Property | Value |
|---|---|
| Request Headers | None |
| Rule Name | BaseData |
| Logging | Production |
| Poll Period | 60 |
| Enable Server Subscription | Yes |

Reference HTTP API Requests
cURL Reference Request (alerts.status)
curl --user edge:edge http://<NetcoolHttpEndPoint>/objectserver/restapi/alerts/status
cURL Reference Request (database/table)
curl --user edge:edge http://<NetcoolHttpEndPoint>/objectserver/restapi/database/table
Filtering Query to alerts.status (Node=’hostname.domain’)
curl --user edge:edge http:/<NetcoolHttpEndPoint>/objectserver/restapi/alerts/status?filter=Node%3D%27hostname.domain%27
Specifying the Columns List to Return (ex: Serial,Node,Summary)
curl --user edge:edge http://<NetcoolHttpEndPoint>/objectserver/restapi/alerts/status?collist=Serial%2CNode%2CSummary
Specifying the OrderBy parameter to Return (ex: Serial ASC)
curl --user edge:edge http://<NetcoolHttpEndPoint>/objectserver/restapi/alerts/statusstatus?orderby=Serial%20ASC
Specifying the Filter, Collist, OrderBy parameters in one request (ex: Serial ASC)
curl --user edge:edge http://<NetcoolHttpEndPoint>/objectserver/restapi/alerts/statusstatus?filter=Node%3D%27hostname.domain %27&collist=Serial%2CNode%2CSummary&Serial%20ASC&orderby=Serial%20ASC
Alternative Approach Configuring the JSON Restful Post with a SQL Command
curl -k -L -X POST -H 'Content-Type: application/json' -d '{ "sqlcmd" : "select * from alerts.status;" }' -u 'edge:edge' 'http://servername:8080/objectserver/restapi/sql/factory'
Feed Name: AlertsCommand
Start URI: /objectserver/restapi/sql/factory
HTTP Method: POST
Request Body:
{ "sqlcmd": "select * from alerts.status;" }
Request Header: Key: Content-Type Value: application/json
