When logged in to Grafana (port 3000, admin/admin) create a datasource that points to the local InfluxDB. Now import the provided dashboards.


## Download and Install svci

```shell
wget https://git.data.coop/api/packages/nellemann/generic/svci/v0.0.3/svci-0.0.3-1.noarch.rpm
rpm -ivh svci-0.0.3-1_all.rpm
cp /opt/svci/doc/svci.toml /etc/
cp /opt/svci/doc/svci.service /etc/systemd/system/
