In addition, we recommend enabling TLS connections and password authentication from Prometheus to node_exporter and jmx_exporter and for Grafana. We recommend installing the resources in a private subnet where possible for production. You should also be aware that some of the resources deployed by this stack incur costs when they remain in use.įor purposes of this post, the resources are installed in a VPC with a public subnet. Please review and customize it as needed. We provide the CloudFormation template in this post as a general guide. The IAM user has permissions to create an IAM role and policies, create SNS topics, launch an EMR cluster, and create stacks in AWS CloudFormation.An AWS Identity and Access Management (IAM) user with an access key and secret access key to configure the AWS Command Line Interface (AWS CLI).An AWS account that provides access to AWS services.Prerequisitesīefore getting started, you must have the following prerequisites:
You can subscribe to the topic to receive the alerts via email, SMS, HTTP/S, Amazon Simple Queue Service (Amazon SQS), or AWS Lambda. Receivers that send events to PagerDuty, Slack, Opsgenie, and others, are natively supported by the Alertmanager.īecause there is no native integration of the Alertmanager with Amazon SNS, we use an implementation of the generic webhook receiver, alert_sns_forwarder, to transform and route the notification message to a pre-configured topic in Amazon SNS.
The Alertmanager takes care of deduplicating, grouping, and routing the notifications to the receivers. You can set up alerts in Prometheus when the alert thresholds are breached, the Prometheus server pushes alerts to the Alertmanager. When a user opens the Grafana dashboards in their browser, the Grafana server queries the Prometheus server to generate the dashboards that are displayed in the browser. These metrics are then stored locally on the Prometheus server. The Prometheus server polls the endpoints exposed by these exporters on each node to gather the metrics. Node_exporter and jmx_exporters collect metrics from the operating system and applications such as YARN and HDFS, respectively, on each node in the EMR cluster. The following diagram illustrates the solution architecture.Įxporters are agents that gather metrics from the systems being monitored and provide endpoints for Prometheus to poll the metrics.
#JMX EXPORTER HOW TO#
In this post, we show how to integrate Prometheus, an open-source systems monitoring and alerting tool, and Grafana, an open-source visualization and analytics tool, to provide an end-to-end monitoring system for EMR clusters. Viewing how the clusters are being used over time helps operations and engineering teams find potential performance bottlenecks and optimization opportunities to scale out or scale in their clusters and plan for capacity. Monitoring Amazon EMR clusters is essential to help detect critical issues with the applications or infrastructure in real time and identify root causes quickly. # irate(process_cpu_seconds_total 0.Amazon EMR is a big data service offered by AWS to run Apache Spark and other open-source applications on AWS in a cost-effective manner.
