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.
Let’s Begin
In this guide I will take you through the steps to get Scrutiny up and running in Docker.
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 Windows Terminal however the steps will be similar on Mac and Linux,
Head into the DSM Control Panel > Terminal & SNMP and then enable SSH service.
![](https://drfrankenstein.co.uk/wp-content/uploads/2022/07/image-1-20220724-204827.png)
Open up ‘‘Terminal’
![](https://drfrankenstein.co.uk/wp-content/uploads/2023/05/image-104.png)
Now type ‘ssh’ then your main admin account username @ your NAS IP Address and hit Enter
ssh drfrankenstein@192.168.0.101
![](https://drfrankenstein.co.uk/wp-content/uploads/2023/05/image-105.png)
You will then be asked to enter the password for the user you used you can either type this or right click in the window to paste (you won’t see it paste the info) then press enter.
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. You will see permission denied errors, but these can be ignored.
fdisk -l
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
![](https://drfrankenstein.co.uk/wp-content/uploads/2022/07/image-1-20220725-204733.png)
The 1821+ has 8 drives broken down into SATA and NVME devices, sata1
to sata8
with the nvme0n1
and nvme1n1
. (Note if you have any eSATA devices connected these will also show)
![](https://drfrankenstein.co.uk/wp-content/uploads/2022/08/vdlGDmQe3F.jpg)
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.
![](https://drfrankenstein.co.uk/wp-content/uploads/2022/07/image-1-20220725-193101.png)
Then if you don’t have one already from my other guides create another folder in the ‘docker’ share called ‘projects’ and within that another one called ‘scrutiny’
![](https://drfrankenstein.co.uk/wp-content/uploads/2023/05/image-106.png)
Next comes the config files, You can edit this file in a number of ways, but to keep the guide OS-agnostic we will be using the Synology Text Editor package which can be installed via Package Center.
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!)
![](https://drfrankenstein.co.uk/wp-content/uploads/2022/07/image-1-20220725-195515.png)

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
![](https://drfrankenstein.co.uk/wp-content/uploads/2022/07/image-1-1024x719.png)
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 level of notification you receive (Critical or All Issues) can be set up in the WebUI once Scrutiny is up and running.
![](https://drfrankenstein.co.uk/wp-content/uploads/2022/08/image.png)
Finally, save this file as ‘scrutiny.yaml’ into the /docker/scrutiny folder.
Docker Compose
We will be using Docker Compose in the Projects section of Container Manager to set up the container.
Open up Container Manager and click on Project then on the right-hand side click ‘Create’.
![](https://drfrankenstein.co.uk/wp-content/uploads/2023/05/image-107.png)
In the next screen we will set up our General Settings ‘Project Name’ will be ‘scrutiny’ the ‘Path’ click the button and select the folder we created earlier in ‘/docker/projects/scrutiny’. ‘Source:’ change the drop-down to ‘Create docker-compose.yml’.
Next we are going to drop in our docker compose configuration copy all the code in the box below and paste it into line ‘1’ just like the screenshot.
![](https://drfrankenstein.co.uk/wp-content/uploads/2023/05/image-108.png)

- COLLECTOR_CRON_SCHEDULE=0 23 * * *
network_mode: synobridge
security_opt:
- no-new-privileges:true
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:/dev/sata1 or /dev/sda:/dev/sda and so on.
In addition to this you will see in the ‘environment’ section three variables that will need to be updated as outlined below, these secure the database used by scrutiny.
Variable | Value |
---|---|
SCRUTINY_WEB_INFLUXDB_TOKEN | enter a sting of characters you can use almost anything treat it like a password so a nice long string |
SCRUTINY_WEB_INFLUXDB_INIT_USERNAME | This can be anything you like |
SCRUTINY_WEB_INFLUXDB_INIT_PASSWORD | a secure password |
COLLECTOR_CRON_SCHEDULE | 0 23 * * * This overrides the default cron schedule at midnight and runs at 23:00 |
These 3 values are only required for the first ever setup – you can remove them once Scrutiny is up and running but keep them safe in case you ever need them. Maybe in Vaultwarden!
Once you have made the edits press ‘Next’
You do not need to enable anything on the ‘Web portal settings’ screen click ‘Next’ again.
![](https://drfrankenstein.co.uk/wp-content/uploads/2023/05/image-109.png)
On the final screen click ‘Done’ which will begin the download of the container image and once downloaded they will be launched!
![](https://drfrankenstein.co.uk/wp-content/uploads/2023/05/image-111.png)
![](https://drfrankenstein.co.uk/wp-content/uploads/2023/05/image-112.png)
You will now see Scrutiny running and should have a green status on the left-hand side.
You should now be able to access the Scrutiny WebUI by going to your NAS IP followed by port 6090
e.g., 192.168.0.30:6090
![](https://drfrankenstein.co.uk/wp-content/uploads/2022/08/image-1-1024x743.png)
Sometimes it can take a few minutes before all your drives appear, as Scrutiny needs to obtain their information so don’t panic if it’s initially empty. You can now adjust settings for the UI and Notifications in the WebUI.
FAQ (Frequently Asked Questions)
I added extra drives to my config, and they don’t appear in the UI even after waiting
You can overcome this by stopping the overall Project and then rebuilding it via Action > Build in the Container Manager UI

Hello, now I have everything installed and everything works great 🙂
The only thing I don’t understand is what is the “8086:8086” #influxDB port for?
When I open the web page it asks me for a username and password, I tried the one I put in the variables, but it can’t accept it.
THANKS
Hey – The InFlux database is used to store the data Scrutiny generates – you should be able to log in via the username and password you generated.
Thanks for your reply. Unfortunately, everything I’ve tried doesn’t work, I don’t know where the name and password are generated, in the variables?
So you should have created them as part of the compose/yaml copied from the guide above.
environment:
– SCRUTINY_WEB_INFLUXDB_TOKEN=ANYLONGSTRING
– SCRUTINY_WEB_INFLUXDB_INIT_USERNAME=A-USERNAME
– SCRUTINY_WEB_INFLUXDB_INIT_PASSWORD=A-PASSWORD
Keep in mind that you will rarely if ever need to use the database and the Web UI for Scrutiny is on port 6090
I missed that, I will correct it tomorrow. Door 6090 works without problems, I wanted to check door 8086 just out of curiosity 🙂
Thanks a lot!
Ha no worries 🙂
Everything went well for me until the final step: going to my NAS IP:6090 I just get Chrome saying “This page isn’t working. “my NAS IP” didn’t send any data. ERR_EMPTY_RESPONSE”
Check the logs for the container for errors as something may be stopping it starting up
Thanks for the response! The logs showed an error regarding the password having to be “at least 8 characters long” despite it actually being 20 characters. Weird, but okay. I regenerated another 20-character password but without special characters, and it seems to like that one. Now it’s up and running.
OK I will add a amendment regarding the password
Thanks
ok i missed this folder 😉
Part when I tried to compile the project I got an error like this?
Bind mount failed: ‘/volume1/docker/scrutiny/influxdb’ does not exists
Hi Dr_Frankenstein,
Great to read your post about deploy Scrutiny.
Just followed to install but failed to start.
“panic: failed to check influxdb setup status – parse “://:”: missing protocol scheme”
May I know what’s missing ?
Thanks
Hey
Just did some searches as not come across this yet. I assume you didn’t already have this setup using the Linuxserver image
https://github.com/AnalogJ/scrutiny/blob/master/docs/TROUBLESHOOTING_INFLUXDB.md#upgrading-from-v03x-to-v04x
Can you initially just try stopping the project and building again.
it’s working now.
Thanks
Nice one
