Heartbeat Monitoring Requirements

Background

Heartbeat is intended to provide a basic monitoring facility to our operational staff to detect outages before they are reported.

An HTTP POST request to a monitoring server within the local network
The application should have a configurable monitoring server IP address and port.
Example of payload / body: “{ arg: { version: "1.0.1", localtime: “2018-11-16T12:34:23.234Z” } }”
Configurable heartbeat interval with a default of 120 seconds
Configurable on/off state to enable or disable the heartbeat
The overall experience is not impacted by a slow response from the monitoring service.

Payload parameters are:

version: string – release number (following semantic versioning)
localtime: string – local time of the device (ISO8601) “YYYY-MM-DDTHH:mm:ss.sssZ”
