Amazon Managed Service for Prometheus now supports out of order sample ingestion

Amazon Managed Service for Prometheus Updates

Amazon Managed Service for Prometheus now supports out-of-order sample ingestion and a workspace-level rule query offset. These features help reduce data loss and improve alerting accuracy for workloads with distributed collectors, batched exports, or variable network latency.

Key Features

• Out-of-order sample ingestion: All workspaces have a default out-of-order time window of 1 minute, allowing the workspace to accept metric samples arriving outside strict chronological order. You can adjust this window or set it to 0 to disable the feature.
• Rule query offset: Introduces a delay before rule evaluation queries run, giving late-arriving samples time to be ingested before rules execute.
• New CloudWatch metrics: OutOfOrderIngestionRate and OutOfOrderSampleAge provide visibility into ingestion patterns, helping you tune settings for your workload.

What to do

• Configure the out-of-order time window and rule query offset in your workspace settings via AWS console, API, or CLI.
• Monitor new CloudWatch metrics to tune your settings.

These features are available in all AWS regions where Amazon Managed Service for Prometheus is generally available. For more information, see the Amazon Managed Service for Prometheus user documentation.
