Quick start

This example show case how one can use a metricsTrait to add prometheus monitoring capability to any workload that emits metrics data.

Install Vela core

kubectl apply -f charts/third_party/cert-manager
kubectl apply -f charts/third_party/prometheus
make docker-build
kubectl create ns vela-system
helm install kube --namespace vela-system charts/vela/

Install OAM Prometheus

kubectl apply  -f config/oam/prometheus-oam.yaml

Run ApplicationConfiguration

kubectl apply -f config/samples/application/
workloaddefinition.core.oam.dev/deployments.apps created
traitdefinition.core.oam.dev/services created
traitdefinition.core.oam.dev/metricstraits.standard.oam.dev created
component.core.oam.dev/sample-application created
applicationconfiguration.core.oam.dev/sample-application-with-metrics created

Verify that the metrics are collected on prometheus

kubectl --namespace oam-monitoring port-forward svc/prometheus-oam  4848

Then access the prometheus dashboard via http://localhost:4848

Verify that the metrics showing up on grafana

kubectl --namespace oam-monitoring port-forward service/monitoring-grafana 3000:80

Then access the grafana dashboard via http://localhost:3000. You shall set the data source URL as http://prometheus-oam:4848

Setup Grafana Panel and Alert

kubectl apply -f config/samples/application/dashboard/OAM-Workload-Dashboard.yaml

Import the dashboard stored in config/samples/application
