When the Consul serf health check is failing, this means that the health checks registered with the agent may no longer be correct. Therefore we show a notice to the user when we detect that the serf health check is failing both for the health check listing for nodes and for service instances.
There were a few little things we fixed up whilst we were here:
- We use our @replace decorator to replace an empty Type with serf in the model.
- We noticed that ServiceTags can be null, so we replace that with an empty array.
- We added docs for both our Notice component and the Consul::HealthCheck::List component. Notice now defaults to @type=info.
