Hands-On Microservices with Kubernetes

Determining alert channels

Alert channels are tightly coupled to severity levels. Let's consider the following options:

• Wake-up call to on-call engineer
• Instant message to a public channel
• Email

Often, the same incident will be broadcasted to multiple channels. Obviously, the wake-up call is the most intrusive, the instant message (for example, slack) may pop up as a notification, but someone has to be around and look at it. The email is often more informative in nature. It is common to combine multiple channels. For example, the on-call engineer gets the wake up call, the team incident channel gets a message, and the group manager gets and email.
