Amazon Managed Service for Prometheus Cheat Sheet

• A managed monitoring service for container environments.

• You can monitor and alert on the performance of containerized workloads using the open-source PromQL without having to scale or manage the underlying infrastructure.

• Automatically scale the ingestion, storage, alerting, and querying of operational metrics as workload increases.

• Integrated with Amazon EKS, Amazon ECS, and AWS Distro for OpenTelemetry.

Amazon Managed Service for Prometheus Features

• With Prometheus query language (PromQL), you can easily obtain performance visibility using a filter, aggregate, and alarm on metrics.

• Supports multi-AZ replication within an AWS Region.

• Collect and query metrics from container clusters on AWS and on-premises.

Amazon Managed Service for Prometheus Concepts

• Workspace

  • A logical space dedicated to storage and querying of metrics.

  • Supports one or more workspaces in each Region.

  • Metrics ingested into a workspace can only be stored for 150 days.

  • Supports multiple rule files.

• Rules

  • To use rules in Prometheus, you’ll need to create YAML rule files.

  • Each rules file is contained under its own namespace.

  • Rules are organized into rules groups within a rules file and are evaluated in order from top to bottom.

• Recording rules

  • You can precompute frequently used or computationally expensive expressions and save the results as a new collection of time series.

  • Querying precomputed result is much faster than running the original expression.

• Alerting rules

  • Create alert conditions based on PromQL and a threshold.

  • A notification is sent to the alert manager when a rule triggers the threshold and forwards it to Amazon SNS.

• Alert manager

  • Supports deduplication, grouping, and routing of alerts to downstream receivers.

  • You can also silence and inhibit alerts.

  • Configuration file

    • Grouping – collects similar alerts into a single notification.

    • Inhibition – suppresses notifications if certain alerts are already firing.

    • Silences – mute alerts for a specified time.

• Templating is stored in the same alert manager configuration file as your alert manager configuration.

• Supports tagging for workspaces and rule groups namespaces.

Amazon Managed Service for Prometheus Pricing

• You are charged based on metrics ingested, queried, and stored.

• Metrics ingested and stored are only charged when you send metrics to Prometheus.

• PromQL Query Samples Processed (QSP) is charged on a per-billion basis.

• Storage fees are calculated depending on the compressed size of metric samples and metadata.

• There are no charges for data transfer in.
