rpm -ivh influxdb-1.8.10.x86_64.rpm
systemctl daemon-reload
systemctl enable influxdb
systemctl start influxdb

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 HMCi

Download the latest version of HMCi packaged for rpm.

wget https://git.data.coop/api/packages/nellemann/generic/hmci/v1.4.2/hmci-1.4.2-1.noarch.rpm
rpm -ivh hmci-1.4.2-1_all.rpm
cp /opt/hmci/doc/hmci.toml /etc/
cp /opt/hmci/doc/hmci.service /etc/systemd/system/
systemctl daemon-reload
systemctl enable hmci
systemctl start hmci

Now modify /etc/hmci.toml (edit URL and credentials to your HMCs) and test the setup by running /opt/hmci/bin/hmci -d in the foreground/terminal and look for any errors. Press CTRL+C to stop and then start as a background service with systemctl start hmci. You can see the log/output by running journalctl -f -u hmci.
