Webhook
A subscription that the
application/web server sends to each agent in the cluster. MC creates a webhook when it connects to the agent, and the agent stores this information in local memory and on disk.When MC executes a long-running job on an agent, such as a create-database operation, the agent uses the webhook subscription to send messages back to MC. If an agent on a cluster node stops while the MC is monitoring the database cluster during a long-running job, MC discovers that the agent is down and switches to another agent in that cluster.
