 ## Collecting Metrics
 
+Create network for being able to communicate between two separate
+docker images
+
+```bash
+docker network create grafana-prometheus
+```
+
 To collect the metrics in an automated way we use Prometheus.
 First, make sure that every service you want to observe is running on predefined port.
 Then run Prometheus in docker with respect to location of `prometheus.yml` file:
 
 ```bash
-docker run --rm --name prometheus -p 9090:9090 -v ${PWD}/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus:v2.43.0 --config.file=/etc/prometheus/prometheus.yml
+docker run --rm --name prometheus --network grafana-prometheus --network-alias prometheus -p 9090:9090 -v ${PWD}/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus:v2.43.0 --config.file=/etc/prometheus/prometheus.yml
+```
+
+## Grafana
+
+Run Grafana in separate container:
+
+```bash
+docker run --rm --name grafana --network grafana-prometheus -p 3000:3000 grafana/grafana:9.1.7
 ```
+
+1. Log into Grafana with default user and password is `admin`.
+2. Add data source in Configuration -> Data sources (http://prometheus:9090)
+3. Import Dashboard as JSON file (two options provided)
