# hello-grafana-prometheus
Just a playground for getting started with Prometheus and Grafana.
### Components
- App (node.js)
- Prometheus Server
- Node Exporter
- Grafana Server
### Run
```
docker-compose up
```
###### Grafana datasources (automatic.yml)
```yml
datasources:
- name: Prometheus
type: prometheus
access: proxy
orgId: 1
url: http://prometheus:9090
```
###### App metrics scraping (prometheus.yml)
```yml
scrape_configs:
- job_name: 'app'
scrape_interval: 5s
static_configs:
- targets: ['app:9091']
```
###### prom-client
```js
const counter = new prometheus.Counter({
name: 'app_http_request_total',
help: 'http request total metric',
labelNames: ['route', 'method', 'status']
});
counter.labels('/path/to/', 'GET', '200').inc();
app.get('/metrics', (_, res) => {
res.set('Content-Type', prometheus.register.contentType)
res.end(prometheus.register.metrics())
})
```
### Extra
- After connecting your data source, you can import the **node-exporter** metrics
dashboard just copying its dashboard ID (405) in Grafana: *Create - Import*.
