When dealing with IoT fleets, one of the major concerns is monitoring to monitor the devices' health status. The "health status" is a generic expression that may include tons of parameters, ranging from the system-on-chip's temperature to the number of processes running in Linux's user space.

The IoT device used for this TN is an [[MISC-TN-004:_Running_Debian_(armbian)_on_SBCSPG|SBCSPG IIoT gateway]] running Debian [[MISC-TN-026:_Automated_test_equipment_(ATE)_monitoring_with_SBCSPG_gateway,_ThingsBoard_IoT,_and_Fledge|Bullseye]] GNU/Linux distribution. An instance of Glances runs on SBCSPG for collecting data (CPU load, memory usage, network traffic, etc.). These data are pushed into an InfluxDB database. Grafana retrieves these data from the database and shows them in a beautiful dashboard. For the sake of simplicity, Grafana and InfluxDB were installed on the same hostrunning Ubuntu 20.04, but they can indeed run on different machines. ==Installing InfluxDB 2.0 and Grafana==Please follow the instructions available [https://medium.com/@nanditasahu031/integration-of-influxdb2-with-grafana-28b4aebb3368 here], but refer to [https://repos.influxdata.com/ these page] for the InfluxDB GPG key to use. For convenience, a ready-to-use dashboard was installed, which is available [https://grafana.com/grafana/dashboards/2387-glances-for-flux/ here]. For accessing the bucket from Grafana, use the API token provided by InfluxDB. It can be copied from the page shown in the following picture.
