Utility for scraping Prometheus metrics from a Prometheus client endpoint and publishing them to CloudWatch
This project is part of our comprehensive "SweetOps" approach towards DevOps.
It's 100% Open Source and licensed under the APACHE2.
NOTE: The module accepts parameters as command-line arguments or as ENV variables (or any combination of command-line arguments and ENV vars). Command-line arguments take precedence over ENV vars
|Command-line argument||ENV var||Description|
|aws_access_key_id||AWS_ACCESS_KEY_ID||AWS access key Id with permissions to publish CloudWatch metrics|
|aws_secret_access_key||AWS_SECRET_ACCESS_KEY||AWS secret access key with permissions to publish CloudWatch metrics|
|cloudwatch_region||CLOUDWATCH_REGION||CloudWatch AWS Region|
|cloudwatch_publish_timeout||CLOUDWATCH_PUBLISH_TIMEOUT||CloudWatch publish timeout in seconds|
|prometheus_scrape_interval||PROMETHEUS_SCRAPE_INTERVAL||Prometheus scrape interval in seconds|
|prometheus_scrape_url||PROMETHEUS_SCRAPE_URL||The URL to scrape Prometheus metrics from|
|cert_path||CERT_PATH||Path to SSL Certificate file (when using SSL for
|keyPath||KEY_PATH||Path to Key file (when using SSL for
|accept_invalid_cert||ACCEPT_INVALID_CERT||Accept any certificate during TLS handshake. Insecure, use only for testing|
|additional_dimension||ADDITIONAL_DIMENSION||Additional dimension specified by NAME=VALUE|
|replace_dimensions||REPLACE_DIMENSIONS||Replace dimensions specified by NAME=VALUE,...|
NOTE: If AWS credentials are not provided in the command-line arguments (
or ENV variables (
the chain of credential providers will search for credentials in the shared credential file and EC2 Instance Roles.
This is useful when deploying the module in AWS on Kubernetes with
which will provide IAM credentials to containers running inside a Kubernetes cluster, allowing the module to assume an IAM Role with permissions
to publish metrics to CloudWatch.
Build Go program
go get CGO_ENABLED=0 go build -v -o "./dist/bin/prometheus-to-cloudwatch" *.go
export AWS_ACCESS_KEY_ID=XXXXXXXXXXXXXXXXXXXXXXX export AWS_SECRET_ACCESS_KEY=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX export CLOUDWATCH_NAMESPACE=kube-state-metrics export CLOUDWATCH_REGION=us-east-1 export CLOUDWATCH_PUBLISH_TIMEOUT=5 export PROMETHEUS_SCRAPE_INTERVAL=30 export PROMETHEUS_SCRAPE_URL=http://xxxxxxxxxxxx:8080/metrics export CERT_PATH="" export KEY_PATH="" export ACCEPT_INVALID_CERT=true ./dist/bin/prometheus-to-cloudwatch
Build Docker image
NOTE: it will download all
Go dependencies and then build the program inside the container (see
docker build --tag prometheus-to-cloudwatch --no-cache=true .
Run in a Docker container
docker run -i --rm \ -e AWS_ACCESS_KEY_ID=XXXXXXXXXXXXXXXXXXXXXXX \ -e AWS_SECRET_ACCESS_KEY=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX \ -e CLOUDWATCH_NAMESPACE=kube-state-metrics \ -e CLOUDWATCH_REGION=us-east-1 \ -e CLOUDWATCH_PUBLISH_TIMEOUT=5 \ -e PROMETHEUS_SCRAPE_INTERVAL=30 \ -e PROMETHEUS_SCRAPE_URL=http://xxxxxxxxxxxx:8080/metrics \ -e CERT_PATH="" \ -e KEY_PATH="" \ -e ACCEPT_INVALID_CERT=true \ prometheus-to-cloudwatch
Run on Kubernetes
kube-state-metrics - to generates metrics about the state of various objects inside the cluster, such as deployments, nodes and pods
prometheus-to-cloudwatch - to scrape metrics from
kube-state-metricsand publish them to CloudWatch
helm install stable/kube-state-metrics
Find the running services
kubectl get services
Copy the name of the
kube-state-metrics service (e.g.
gauche-turtle-kube-state-metrics) into the ENV var
PROMETHEUS_SCRAPE_URL in values.yaml.
It should look like this:
cd chart helm install .
prometheus-to-cloudwatch will start scraping the
/metrics endpoint of the
kube-state-metrics service and send the Prometheus metrics to CloudWatch
