The service is integrated with AWS EKS, ECS, and Distro for OpenTelemetry.

What is AWS Prometheus?

What is AWS Prometheus

Prometheus enables real-time alerts and monitoring. It provides a flexible query language for aggregating metrics across a high volume of labels. Those are value pairs such as regions equal US East-1, environment equal production, and equal e-commerce. Some unique features of Prometheus include its instrumentation libraries, supported in languages such as GO, Java, and C#, and its ability to pull metrics at scale from over 150 plus exporters including JMX, Redis, and Nginx all maintained by the open source community.

Amazon Prometheus is a managed monitor and alert service that delivers information and real-time insights for large-scale container deployments. You may gather and retrieve operation and performance information from container applications on AWS as well as on using Amazon Prometheus.

Amazon Prometheus managed service, automates Prometheus installation and configuration, and automates most of the regular maintenance and operations allowing you to save time maintaining your monitoring system and even more for creating the apps.

Amazon Prometheus scales with the container's workload to give price-effective performance measurements and reliable query reaction times. To gather and analyze data using AWS container services like AWS EKS, AWS ECS, and AWS Fargate, users may utilize Amazon Prometheus.

  • Filtering, aggregating, ingestion, and querying thousands of pivotal moment series metrics across the self-managed Kubernetes cluster user can utilize the Prometheus query language.
  • Scale dynamically as the ingest and query requirements expands, while maintaining constant reaction speeds with massive container installations.
  • Integration with AWS security services to satisfy the organization's compliance and safety needs.
  • Lower the operating expenses of solitary Prometheus server configuration, upgrade, and scalability.

How AWS Prometheus Works?

How AWS Prometheus Works

Amazon Managed Service for Prometheus supports container clusters running on Amazon Elastic Kubernetes Service as well as self-managed Kubernetes deployments.

The same open-source Prometheus data schema and PromQL query language that you use with Prometheus are used with Amazon Managed Service for Prometheus. Engineering teams may utilize PromQL to filter, aggregate, and alert on metrics to acquire performance information rapidly and without modifying code. Amazon Managed Service for Prometheus enables customizable query capabilities while reducing operating costs and complexity.

Metrics entered into a workspace are kept for 150 days before being automatically erased.

Use Cases of AWS Prometheus

  • Integrated Application Monitoring

Monitor AWS container and heterogeneous systems, and interact with AWS Grafana to monitor alarms, and dashboard insights.

  • Diagnosis and Root Cause Assessment

With notifications, you can watch container efficiency and system health, detect issues, and minimize the median time to resolve them.

  • Monitor the Workload and Metric of the Application

Utilizing AWS Distro on OpenTelemetry, gather measurements from any location and transmit them to Amazon Prometheus by open-source exporters.

  • Monitor the Higher Cardinalities Metric

Monitor and notify on high-cardinality information, such as streaming video, networking technologies, and Internet of things time series information.

AWS Prometheus Ecosystem and Architecture

AWS Prometheus Ecosystem and Architecture

Prometheus is an open-source monitoring system  comprised of the following elements:

  • Prometheus Server : collects and stores time series data from programs like web applications for local study. The push gateways, which are typically HTTP endpoints, are used by the Prometheus server to extract metrics data from a variety of applications and systems. The data is kept local as time-serialized data metrics after being collected on the Prometheus server so that it may later be used for evaluation and additional monitoring using the alert management.
  • Prometheus Client Libraries : The monitoring of application code is possible thanks to Prometheus client libraries. To link their applications to Prometheus and provide statistics, programmers may utilize such libraries, which are available in several languages like Go, C#, Ruby, Java, Python, and many others.
  • Send Gateway : Acts as a channel for batch jobs and ephemeral jobs to transmit information during their brief processes.
  • Exporters : Libraries that enable the exporting of measurements from other platforms as Prometheus observations.
  • Alert Manager : Gives the user the ability to manage alerts via push notifications.

Prometheus is intended to be a reliable, independent engine with no reliance on extraneous parts. When one of the major portions of an app or the infrastructure management fails, it can be utilized for various app troubleshooting and diagnosis.

The multi-dimensional data set used by Prometheus frequently maintains data as time series information with time stamp results for every parameter. Every time series has a unique "metric name" identifier and tags, which are optionally key-value pairs.

For real-time analysis of the time series information it saves, Prometheus also comes with PromQL, which stands for Prometheus Query Language. The Prometheus server's HTTP API may be used to import the outcomes of such queries into external applications or show them as tables or maps.

Prometheus allows storing and analysis of temporarily generated time-series information produced by various PromQL inquiries that also have labels in addition to time-series information.
