description:
 This check monitors the link monitors (SD-WAN health checks) of a
 Fortigate firewall. It reports the state of the link monitor and
 the measured latency, jitter and packet loss.

 The check becomes {crit} (configurable) if the link monitor is dead.
 Levels for latency, jitter and packet loss can be configured with the
 rule "FortiOS link monitors".

 The special agent is required for this check,
 which can be configured via "FortiOS".

discovery:
 One service per monitored server/interface of a link monitor is created
 (a health-check spanning multiple WAN interfaces results in one service per interface).
