Definition

All healthcheck properties are contained within the healthcheck object in the IAP Service Instance Configuration for the adapter. There is a “healthcheck” action defined in the .system entity that is used to define the healthcheck request. The path to the healthcheck file is adapter/xyz/entities/.system/action.json.

Note: Often, the healthcheck endpoint is set to /healthcheck by default because the best healthcheck API call has yet to be determined. If you want healthchecks to work, you must determine a good enpoint and set it accordingly.

Property	Type	Required	Description
`type`	enum	Yes	The type of healthcheck to use. none: Does not run any healthchecks. In this situation the adapter will always show the status as green. startup: Run a healthcheck at start up only. If the healthcheck works, then the status will show as green. If the healthcheck fails, the status will show as red. The status will not be updated. intermittent – Run healthchecks at a defined interval. The status is as of the last time healthcheck ran. It will be updated based on the results of the healthcheck API each time the call is made.
`frequency`	integer	Yes (if intermittent)	The frequency in which to run intermittent healthchecks. Measured in milliseconds (ms).
`query_object`	object	No	An object containing query variables to add onto the healthcheck call.

Example Scenario

In this example, a healthcheck is set to run every 5 minutes (300s – 300000ms).
The call for the healthcheck is a GET method: https://mysystem.abc.com:3443/api/rest/v2.3/getSystemStatus The host, port, base_path, and version are defined in the IAP Service Instance Configuration for the adapter. The path defined here is just /getSystemStatus.
The data in the response is not the primary focus here, but rather that we got a response. For this example, we can use the default schema with no translation.
We want to add a query to the call of mytest=hello
