Open app url, and create some people, do some mess.
- Grafana
I suggest to take a look on grafana tutorials, for example Grafana fundamentals.
Add DS(data source) in our case - prometheus. Configuration -> Add data source -> Prometheus. In url paste http://prometheus:9090 and click Save & test.
Upload dashboards + -> import and select json file from ./app/utils/grafana/grafana.json or feel free to change something in jsonnet and regerate it via make generate_dashboard. Save dashboard.
You should see something like the fallowing image:
- grafana / time series database persistence
- improve grafana dashboards jsonnet templates
- load testing / benchmark (http/models)
- minikube deployment
- logs
- custom metrics
