Install collector on Synology

Install Entware

This will allow you to install a newer version of smartmontools on your Synology. Follow the instructions here (This is tested on DSM7) - https://github.com/Entware/Entware/wiki/Install-on-Synology-NAS

PLEASE NOTE THAT IF YOU UPDATE DSM FIRMWARE YOU MAY BORK THE EXISTING ENTWARE INSTALLATION, FOR ANYTHING THAT MAY RELATE TO ENTWARE PLEASE VISIT THEIR REPO

Collector Setup

1. Run an update

sudo opkg update

2. Run an upgrade

sudo opkg upgrade

3. Install smartmontools

sudo opkg install smartmontools

It should install v7.2-2

Installing smartmontools (7.2-2) to root...

4. We will now create the directories.

mkdir -p /volume1/\@Entware/scrutiny/bin
mkdir -p /volume1/\@Entware/scrutiny/conf

5. change into the bin directory

cd /volume1/\@Entware/scrutiny/bin

6. Download the collector binary for your architecture and make it executable

wget https://github.com/AnalogJ/scrutiny/releases/download/v0.4.12/scrutiny-collector-metrics-linux-arm64

chmod +x /volume1/\@Entware/scrutiny/bin/scrutiny-collector-metrics-linux-arm64

7. Create a config file for the collector

cd /volume1/\@Entware/scrutiny/conf
wget https://raw.githubusercontent.com/AnalogJ/scrutiny/master/example.collector.yaml
mv example.collector.yaml collector.yaml

8. Lets make some changes in the collector config file, these are what i uncommented/added, please tweak the device paths to your needs

host:
  id: 'Server_Name'


devices:
#  # example for forcing device type detection for a single disk
 - device: /dev/sda
   type: 'sat'
 - device: /dev/sdb
   type: 'sat'
 - device: /dev/sdc
   type: 'sat'
 - device: /dev/sdd
   type: 'sat'
    
api:
 endpoint: 'http://<url>:8080'

9. Let's update the smartd db

cd /volume1/\@Entware/scrutiny/bin/
wget https://raw.githubusercontent.com/smartmontools/smartmontools/master/smartmontools/drivedb.h

10. I ran it like this but you can tweak to your liking, the most important part is the --drivedb, as this loads it into the aplication for future use

smartctl -d sat --all /dev/sda --drivedb=/volume1/\@Entware/scrutiny/bin/drivedb.h

11. Now lets create a small bash script, this will be used for the scheduled task inside Synology

vim /volume1/\@Entware/scrutiny/bin/run_collect.sh

The contents are below, copy and paste them in

#!/bin/bash

/volume1/\@Entware/scrutiny/bin/scrutiny-collector-metrics-linux-arm64 run --config /volume1/\@Entware/scrutiny/conf/collector.yaml

Make run_collect.sh executable

chmod +x /volume1/\@Entware/scrutiny/bin/run_collect.sh

Set up Synology to run a scheduled task.
