Process millions of observability events with Apache Flink and write directly to Prometheus
- AWS introduced a new Apache Flink connector for Prometheus, allowing data to be directly sent to Amazon Managed Service for Prometheus.
- Amazon Managed Service for Prometheus enables real-time observability without managing infrastructure, utilizing Prometheus's data model and query language.
- Observability extends beyond IT assets, including IoT devices, and metrics play a crucial role in capturing measurements from these distributed devices.
- Prometheus serves as a specialized time series database for real-time dashboards and alerting, optimized for various distributed assets, not just compute resources.
- Handling observability data at scale poses challenges like high cardinality, frequency, irregular events arrival, lack of contextual information, and deriving metrics from events.
- Preprocessing raw observability events before storing can optimize real-time dashboards and alerting by reducing frequency and cardinality.
- Apache Flink is a suitable engine for preprocessing observability events, allowing efficient enrichment, aggregation, and derivation of metrics at scale.
- The new Flink Prometheus connector seamlessly writes preprocessed data to Prometheus, eliminating the need for intermediate components and scaling horizontally.
- Example use case scenarios demonstrate how preprocessing with Flink enhances visualization and analysis of metrics for improved observability.
- The Flink Prometheus connector optimizes write throughput by parallelizing and batching writes, adhering to Prometheus Remote-Write specifications.
