What is Scrutiny?
Scrutiny is a Hard Drive Health Dashboard & Monitoring solution, merging manufacturer provided S.M.A.R.T metrics with real-world failure rates.
In this guide I will take you through the steps to get Scrutiny up and running in Docker.
In order for you to successfully use this guide please set up your Docker Bridge Network first.
Scrutiny currently cannot be setup via the DSM Docker UI, so we will be using Docker Compose to get things up and running, this is not as complicated as it seems.
Getting our drive details
We need to get some details about our drives in order for Scrutiny to read their SMART data.
It’s time to get logged into your Diskstation via SSH, in this guide I am using Putty on Windows.
Head into the DSM Control Panel > Terminal & SNMP and then enable SSH service.
Open up ‘PuTTY’, the only thing you need to enter is the IP address of your NAS and select the SSH radio button.
Click on ‘Open’, you will get a prompt asking if you trust the key, if this is the first time you have used SSH, just press OK or accept.
Enter the login information for your main Synology user account, you will not be able to see the password as you type it. (If you are using a password manager right-clicking in the window will paste – you won’t be able to see it)
Now we are logged in we just need to do a single command to see our drives, note I am not prefacing this command with sudo as we don’t need the low level detail.
The output you will see depends on the model NAS you own, the two examples below are from an 1821+ and an 1815+ which have 8 bays and the 1821 has up to 2 NVMEs.
The 1815+ has 8 drives broken down from sda to sdh
The 1821+ has 8 drives broken down into SATA and NVME devices, sata1 to sata8 with the single nvme0n1.
Make note of the devices you see in your output as we will need them for the config file and compose.
Config Files and Folders
Next let’s create the folders the container will need. Head into FileStation and create a subfolder in the ‘docker’ share called ‘scrutiny’ and then within that another called ‘influxdb’ it should look like the below.
Next comes the config files, I am going to use the Text Editor from the Package Center for this step.
Open up a new text document and paste one of the two code snippets below into it. Use the one that matches up with the way your drives are shown in the previous step (if you come across anything different let me know in the comments!)
version: 1 devices: - device: /dev/sata1 type: 'sat' - device: /dev/sata2 type: 'sat' - device: /dev/sata3 type: 'sat' - device: /dev/sata4 type: 'sat' - device: /dev/sata5 type: 'sat' - device: /dev/sata6 type: 'sat' - device: /dev/sata7 type: 'sat' - device: /dev/sata8 type: 'sat' - device: /dev/nvme0n1 type: 'nvme'
version: 1 devices: - device: /dev/sda type: 'sat' - device: /dev/sdb type: 'sat' - device: /dev/sdc type: 'sat' - device: /dev/sdd type: 'sat' - device: /dev/sde type: 'sat' - device: /dev/sdf type: 'sat' - device: /dev/sdg type: 'sat' - device: /dev/sdh type: 'sat'
You will need to edit the config file in line with the number of drives you had in the output earlier either adding or removing lines accordingly, including adding or removing the NVME drives.
Next you can save this file as ‘collector.yaml’ in the ‘/docker/scrutiny’ folder.
Notifications Config (optional)
This step is optional and depends on if you want to set up some notifications in case one of your drive has issues.
As of writing there are 14 different notification method, as you can imagine I cannot cover every single type in this guide, but this will get the config file in place for you to amend based on your preferences
Open up a new file Text Editor again, this time you need to copy and paste the full contents of the example config file located here
Scroll to the bottom of the file where you will see a number of config options for notifications. You will need to the remove the # from the ‘notify’ and ‘urls’ lines and then depending on which type of notification you decide to set up the # will need to be removed from the corresponding line.
The types of notification you receive can be set up in the WebUI once Scrutiny is up and running.
Finally, save this file as ‘scrutiny.yaml’ into the /docker/scrutiny folder.
Docker Compose File
We will be using Docker Compose to set up the container. In a nutshell we will be creating a text file (YAML formatted) which tells Docker exactly how we want it set up.
Open up a new file in Text Editor again and copy the code below into it.
version: "3.8" services: scrutiny: container_name: scrutiny image: ghcr.io/analogj/scrutiny:master-omnibus cap_add: - SYS_RAWIO ports: - "6090:8080" # webapp - "8086:8086" # influxDB admin volumes: - /run/udev:/run/udev:ro - /volume1/docker/scrutiny:/opt/scrutiny/config - /volume1/docker/scrutiny/influxdb:/opt/scrutiny/influxdb devices: - /dev/nvme0n1:/dev/nvme0n1 - /dev/sata1:/dev/sata1 - /dev/sata2:/dev/sata2 - /dev/sata3:/dev/sata3 - /dev/sata4:/dev/sata4 - /dev/sata5:/dev/sata5 - /dev/sata6:/dev/sata6 - /dev/sata7:/dev/sata7 - /dev/sata8:/dev/sata8 network_mode: synobridge restart: unless-stopped
As you can see the devices section contains all our drives, you will need to amend this again in line with the config file you created earlier. You will need to amend the paths each side of the : so they match, adding or removing drives accordingly including the NVMEs.
e.g., /dev/sata1:/dec/sata1 or /dev/sda:/dev/sda and so on.
Once you have made the edits save this file as ‘scrutiny.yml’ in ‘/docker/scrutiny’
SSH and Docker-Compose
We are now on the final section, you can now log back into your NAS via SSH again.
Once you have logged in you will need to give 2 commands, you can copy and paste these one at a time — you will need to enter your password for the command starting with ‘sudo’
First we are going to change directory to where the scrutiny.yml is located, type the below and then press enter.
Then we are going to instruct Docker Compose to read the file we created and complete the set-up of the container. Again type or copy the below and press enter.
sudo docker-compose -f scrutiny.yml up -d
When the command has completed you should be able to see Scrutiny running in the list of containers in the Synology GUI.
You should now be able to access the Scrutiny WebUI by going to your NAS IP followed by port 6090
Congrats you are all set up – scrutiny should show all your attached drives you can view the various details and amend your UI settings to your preferences.
