[role="_abstract"]
|
|
Cluster notifications are designed to keep you informed about the health of your cluster and high impact events that affect it.
|
|
|
|
Most cluster notifications are generated and sent automatically to ensure that you are immediately informed of problems or important changes to the state of your cluster.
|
|
|
|
In certain situations, Red{nbsp}Hat Site Reliability Engineering (SRE) creates and sends cluster notifications to provide additional context and guidance for a complex issue.
|
|
|
|
Cluster notifications are not sent for low-impact events, low-risk security updates, routine operations and maintenance, or minor, transient issues that are quickly resolved by Red{nbsp}Hat SRE.
|
|
|
|
Red{nbsp}Hat services automatically send notifications when:
|
|
|
|
* Remote health monitoring or environment verification checks detect an issue in your cluster, for example, when a worker node has low disk space.
|
|
* Significant cluster life cycle events occur, for example, when scheduled maintenance or upgrades begin, or cluster operations are impacted by an event, but do not require customer intervention.
|
|
* Significant cluster management changes occur, for example, when cluster ownership or administrative control is transferred from one user to another.
|
|
* Your cluster subscription is changed or updated, for example, when Red{nbsp}Hat makes updates to subscription terms or features available to your cluster.
|
|
|
|
SRE creates and sends notifications when:
|
|
|
|
* An incident results in a degradation or outage that impacts your cluster's availability or performance, for example, your cloud provider has a regional outage. SRE sends subsequent notifications to inform you of incident resolution progress, and when the incident is resolved.
|
|
* A security vulnerability, security breach, or unusual activity is detected on your cluster.
|
|
* Red{nbsp}Hat detects that changes you have made are creating or may result in cluster instability.
|
|
* Red{nbsp}Hat detects that your workloads are causing performance degradation or instability in your cluster.
