- What happens to the notifications if there's a network partition between Alertmanager instances in the same cluster?
- Can an alert trigger multiple receivers? What is required for that to happen?
- What's the difference between group_interval and repeat_interval?
- What happens if an alert does not match any of the configured routes?
- If the notification provider you require is not supported natively by Alertmanager, how can you use it?
- When writing custom notifications, how are CommonLabels and CommonAnnotations populated?
- What can you do to ensure that the full alerting path is working from end to end?

Overview of this book
Prometheus is an open source monitoring system. It provides a modern time series database, a robust query language, several metric visualization possibilities, and a reliable alerting solution for traditional and cloud-native infrastructure.
This book covers the fundamental concepts of monitoring and explores Prometheus architecture, its data model, and how metric aggregation works. Multiple test environments are included to help explore different configuration scenarios, such as the use of various exporters and integrations. You’ll delve into PromQL, supported by several examples, and then apply that knowledge to alerting and recording rules, as well as how to test them. After that, alert routing with Alertmanager and creating visualizations with Grafana is thoroughly covered. In addition, this book covers several service discovery mechanisms and even provides an example of how to create your own. Finally, you’ll learn about Prometheus federation, cross-sharding aggregation, and also long-term storage with the help of Thanos.
By the end of this book, you’ll be able to implement and scale Prometheus as a full monitoring system on-premises, in cloud environments, in standalone instances, or using container orchestration with Kubernetes.
