# Manual Forecaster test:



- Edit `my_deploy.sh` and enable the `monitoring` and the `forecaster` components.



- Deploy TeraFlowSDN controller:

```bash

source my_deploy.sh

./deploy/all.sh

```



- Onboard the topology descriptor `topology.json` through the WebUI.



- Source the runtime environment variables and inject the link utilization KPI values into the Monitoring database:

```bash

source tfs_runtime_env_vars.sh

python src/forecaster/tests/data/inject_samples.py

```



- Onboard the service descriptor `service.json` through the WebUI.
