Typical severitywarning. A product may set another for its own case.
Applies toEvery connected product, especially those using certificates or schedules

Likely causes

How to fix or prevent it

  1. Check that the product can reach a time server.
  2. Replace the clock battery if it has one.
  3. Set the right time-server address.
  4. Run sync_time if the product offers it.

What the HEART does by itself

It raises a warning and marks the times it records as uncertain. A Playbook may run sync_time. It resolves once the clock has been checked against a time source. A wrong clock matters: certificates, logs and schedules depend on it.

When to call service

If the clock keeps drifting or resetting after a new battery.


Inside a message a code is written bare, "code": "storage.full". In logs, tickets, documents and searches it is written HEART storage.full. Things that simply happen, such as system.started, are event types, not faults. The codes are defined in Part 3, Section 5.4, and their H-numbers in Section 5.7. All of it, as data: fault-codes.json.
