How to Monitor a Raspberry Pi Remotely

I'm working on a project that hosts a group of Raspberry Pi computers in several remote locations. I wanted to be able to monitor the “health” of hardware in those remote locations. The metrics I was hoping to capture are uptime, CPU times, CPU utilization, memory and disk utilization, etc. as you may have noticed, I also have a love/hate relationship with Grafana, which made it the only choice to display these metrics in a friendly way.
Preconditions:
1 x VM running Ubuntu 20.04 - I tested using a Cloud Compute server on VULTR, but you can use any VM that is on the same network as the RPi.

1 x RPi – As long as the RPi is on the same network, everything is fine. I tested through a VPN and that also worked.
Software stack:
Influxdb - As usual, the time series database.

Grafana – My favorite program for displaying this type of data.

Telegraf - A plugin server agent to collect and report hardware metrics such as CPU, Time, RAM, Storage, etc…
Install InfluxDb on VM/Host Install Grafana on VM/Host
PLEASE READ: Now that Grafana and InfluxDb are installed on our host/server. We need to install Telegraf on the RPi whose metrics we want to retrieve. Don't worry, we'll come back and configure Grafana/InfluxDb shortly.
Install Telegraf on Raspberry Pi (RPi) Setup – Telegraf on RPi Telegraf.conf
PLEASE READ: Now that we've finished setting up the Raspberry Pi, it's up to the VM/Host to set up the influx and grafana.
Configuration – InfluxDB on VM/Host Setup – Grafana
Navigate to your Grafana installation: http://:3000

Login: default login is admin:admin

Please change username and password immediately.

The first step is to add the Influxdb data source:

The second step is to import the dashboard - We used this dashboard from the Grafana library:

To import the dashboard, go to DASHBOARD > MANAGE > IMPORT

Insert 10578 in the field and click on "Load"

Then be sure to select the data source to associate with the dashboard.
