As part of the new year, I started rebuilding my home lab to retire my aging Mac Mini ESXi cluster with “new” Dell PowerEdge R220 servers. More on the Dell's later; however, this prompted me to change out my monitoring stack to start utilizing Prometheus’ node exporter. Since node exporter is very lightweight, I decided to start capturing telemetry from my Synology DS1517+ network area storage (NAS). I didn't see any documentation so I wrote something up.
You dependencies installed or configured before we get started:
- SSH enabled on your NAS
- A method to SSH into your NAS
- Putty (Windows)
- Terminal (MacOS/Linux)
- Docker installed on your Synology
The following should help you get node exporter running your Synology.
- SSH into you Synology
- Elevate your privileges to root
- Create and edit a new docker compose file
iand paste in this docker compose template
:, followed by

- Now it is time to run your new container on your NAS by running the following command:
- Navigate to
