Synology NAS Overview

The Synology NAS Overview dashboard was built to give an overall glance at multiple Synology NAS systems and their operational status. It was built to compliment the Synology NAS Detail dashboard (https://grafana.com/grafana/dashboards/14284).

Set the “NASDevices” variable to the number of NAS devices you are monitoring in order for the dashboard to properly report the “Total Synology’s” and “Synology’s Down”.

This dashboard utilizes Prometheus and the snmp_exporter to gather various statistics from Synology NAS devices. It has been tested on DSM 6.2, DSM 7.0, DSM 7.1 and DSM 7.2 utilizing DS1511+, DS1512+, DS1513+, DS918+, DS920+ and DS923+ hardware.

Requires: https://github.com/prometheus/snmp_exporter

Upon the import of the dashboard, you should be prompted for the DataSource. You should also be asked how many NAS devices you plan to monitor.

Variables utilizing Regex are used to filter which Network Interfaces, File Systems and Services are displayed. You can enable or disable them from appearing in the dashboard simply by changing the Regex. Another variable named “interfacebits” allows you to set whether you want your network graphs to show bits or bytes (Megebyte set to 1, Megabits set to 8.).

My snmp.yml files used by me can be found here. https://github.com/tumak66/grafana-prometheus-synology

If you have issues with the DSM Version, Serial Number and the Disk in the Hard Drives section not reporting correctly check your snmp.yml file. Make sure that the following are set to use “type: DisplayString”. Eventhough my generator.yml was configured with overrides they didn’t seem to take affect when generating the snmp.yml file (need to investigate more).
