Labels for the ServiceMonitor passed to Prometheus Operator In Prometheus, an exporter is a component that collects and exposes metrics in a format Prometheus can scrape. curl 127.0.0.1:8080 HELP jvmmemoryobjectspendingfinalization The number of objects waiting in the finalizer queue. I am trying to get metrics from jmxexport into the cloudwatch on the EMR cluster. Path to cloudwatch-exporter telemtery-path Prometheus is a favored open-source monitoring system that collects, stores, and queries metrics from various sources. EMR metrics to cloudwatch via Prometheus. The CloudWatch agent with Prometheus support scrapes the Java/JMX Prometheus metrics based on the service discovery configuration in the Amazon ECS cluster. Exporting CloudWatch metrics to a Prometheus server allows leveraging of the power of PromQL queries, integrating AWS metrics with those from other applications or cloud providers, and creating advanced dashboards for digging down into problems. JMX Exporter is an official Prometheus exporter that can scrape and expose JMX For more information, see prometheus/jmxexporter. Namespace thes Servicemonitor is installed in A Prometheus CloudWatch exporter is a key element for anyone wanting to monitor AWS CloudWatch. Choose one of the sets of dimensions in the following list. In the list of namespaces, choose ContainerInsights/Prometheus or ECS/ContainerInsights/Prometheus. Use servicemonitor from prometheus operator Open the CloudWatch console at In the navigation pane, choose Metrics. Specifies whether a service account should be created. Whether or not the pre-created secret contains an AWS STS session token The name of a pre-created secret in which AWS credentials are stored The following table lists the configurable parameters of the Cloudwatch Exporter chart and their default values. The command removes all the Kubernetes components associated with the chart and deletes the release. To uninstall/delete the my-release deployment: The configuration section lists the parameters that can be configured during installation. The command deploys Cloudwatch exporter on the Kubernetes cluster in the default configuration. $ helm install -name my-release stable/prometheus-cloudwatch-exporter -set awsRole= $ # or add a role to aws with the () to add to cloud watch and pass its name as a value $ helm install -name my-release stable/prometheus-cloudwatch-exporter -set = $ kubectl create secret generic -from-literal=access_key= $AWS_ACCESS_KEY_ID -from-literal=secret_key= $AWS_SECRET_ACCESS_KEY $ # or store them in a secret and pass its name as a value $ helm install -name my-release stable/prometheus-cloudwatch-exporter -set aws.aws_access_key_id= $AWS_ACCESS_KEY_ID,aws.aws_secret_access_key= $AWS_SECRET_ACCESS_KEY Before we start comparing the two technologies, let’s do a quick high-level overview of both.$ # pass AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY as values You can also host a Prometheus instance in the cluster and then metrics are exported to CloudWatch using the CloudWatch adapter. As one of the workarounds, you can use CloudWatch exporter and export metrics from CloudWatch to a Prometheus instance. For example, currently, CloudWatch does not support Kubernetes metrics ( Issue link here). Prometheus and CloudWatch are very different in the problem they solve and a 1-1 comparison seems unfair but as you start moving to cloud-native stack, Prometheus starts popping up in conversations and for many right reasons. This post will try to explore various aspects and pros and cons of both options individually and as a combination. When an organization earlier using VMs in AWS decides to move to Kubernetes (Either EKS or self-managed in AWS), one of the questions that come up is should one continue to use CloudWatch or switch to some other tool like Prometheus? While it is not an exactly apple to apple comparison, there are reasons to explore this and choose tooling that is built for the future. Many companies are moving to Kubernetes as the platform of choice for running software workloads.
