Consul Health Check Warning vs. Critical

[RyanO]

The "warning" and "critical" health check results both trigger the removal of a node from the service.  I'm trying to understand the use case for warning as a means of notification via a watcher vs. removing the node from the service automatically.  Using a simple example of "Nagios Check Disk" where I'd like to be notified about a disk filling up but not remove it from the service if it's not full.  I can't seem to find anything in the documentation that describes this.  Newbie question, sorry.

Thanks,

Ryan

Hi Ryan,

The "only_passing" configuration option controls this for DNS - https://www.consul.io/docs/agent/options.html#only_passing. By default, warnings should not pull a node out of service, but if this is set to true then things will behave as you describe. There's a similar "passing" option you can pass to the health HTTP endpoint - https://www.consul.io/docs/agent/http/health.html#health_service.

It looks like you might have this option set to true in your configuration. Hope that helps!
