Use your preferred REST API client to review the value of the status variable of the API Catalog service that is routed through the API Gateway using the following URL:
https://hostName:basePort/api/v1/apicatalog/application/state
The hostName is set during install, and basePort is set as the gatewayHttpsPort parameter.
Example:
The following example illustrates how to use the curl utility to invoke API Mediation Layer endpoint and the grep utility to parse out the response status variable value
$ curl -v -k --silent https://hostName:basePort/api/v1/apicatalog/application/state 2>&1 | grep -Po '(?<=\"status\"\:\")[^\"]+'
UP
The response UP confirms that API Mediation Layer is installed and is running properly.
