The Netdata Agent checks the overall system health status (-1: unknown, 0: green, 1: yellow, 2: orange,
3: red, 4: grey). This alert indicates that the overall system status is unhealthy. Receiving this alert means that one or more components might become overloaded soon (yellow), or might be degraded (orange), or might be in an unusable status, and the appliance might become unresponsive soon (red).
