hover over forwarded address for the port Labeled Grafana (3000)
click middle icon

Create a dashboard

Create a dashboard(s) that shows:
- Name dashboard CPU_Utilization_Gauge
- cpu utilization Gauge Dashboard
  - Metric should be displayed as Percentage
  - Use node metrics
    - query should be:
```
  scalar(node_load1) * 100 / count(count(node_cpu_seconds_total) by (cpu))`
```
- cpu utilization Time series Dashboard
  - Name dashboard CPU_Utilization_TS
  - Metric should be displayed as Percentage
  - Use node metrics
    - query should be:
```
  scalar(node_load1) * 100 / count(count(node_cpu_seconds_total) by (cpu))`
```

Create an alert

Create an alert for 60% or more CPU utilization
- Create alert folder called bonkey.
- Create alert group called wonkers.
- Evaluation at 10s

Stress system

Execute the following command:

docker run --rm -it j0hnewhitley/docker-stress:v0.0.1 --cpu 4 \
  --io 2 --vm 4 --vm-bytes 4GB --timeout 30s

Demonstrate that alert fired
