Scrutiny - Compose

Scrutiny is a great S.M.A.R.T checker. It both logs the temps and status of all your drives and can also notify to a number of different services if it detects drive degradation.

version: '3.5'
 
services:
  scrutiny:
    container_name: scrutiny
    image: ghcr.io/analogj/scrutiny:master-omnibus
    network_mode: bridge
    cap_add:
      - SYS_RAWIO
    ports:
      - "8250:8080" # webapp
      - "8086:8086" # influxDB admin
    volumes:
      - /run/udev:/run/udev:ro
      - /media/appdata/scrutiny/config:/opt/scrutiny/config
      - /media/appdata/scrutiny/influxdb:/opt/scrutiny/influxdb
    devices:
      - "/dev/sda"
      - "/dev/sdb"
      - "/dev/sdc"
      - "/dev/sdd"
      - "/dev/sde"
      - "/dev/sdf"

Container Parameters

container_name The name of the container.

network_mode Which docker network to connect the container to. Among others can “host” or “bridge” be used.

cap_add This works like a very restrictive version of --privileged. Privileged gives the container ALL capabilities, whilst cap_add ONLY gives the specified capabilities to the container. For more info, refer to this Docker Docs.

Ports

8250 Port for the Web UI

8086 Connect to this port with a app as Adminer to manage the influx database.

Volumes

/run/udev “ro” stands for “Read Only”. udev is necessary for Scrutiny to be able to detect your drives and read S.M.A.R.T info from them

/opt/scrutiny/config Dir for all config files and other necessities for Scrutiny to run

/opt/scrutiny/influxdb A local database Scrutiny saves S.M.A.R.T info into.

Devices

List all your disks here as detected by smartctl --scan when run on your host system. Check Scrutinys Github (linked below) for detailed instructions on what to do in a RAID config.

Notifications

Open scrutiny.yaml in the “/config” directory. Scroll down to the “notify” section and configure as necessary. I only chose Discord and for that, I needed two things. A Webhook and a Token.

The Webhook is created by:

1. Creating a Server (if you dont already have one)
2. Creating a text channel for your notifications (maybe named something like “name-of-computer scrutiny notifs”)
3. Right clicking on the text channel and selecting Edit Channel. Then Integrations → Webhooks and creating a new one.
4. Copy the “Webhook URL” paste into a text editor. Your URL is going to look something like this:
   https://discord.com/api/webhooks/5843905893058345903/jflkFJKLFJklfjdklsf7890f7fs95t87564F566dsf789sfwejwklföjdklsöfudasdF (Dont worry, this one is fake)
5. The first 5843905893058345903 is your Token and the longer jflkFJKLFJklfjdklsf7890f7fs95t87564F566dsf789sfwejwklföjdklsöfudasdF is the Webhook. Paste these into the discord:// in the scrutiny.yaml file. The Webhook goes first, then the Token.
6. Uncomment the line you’ve edited in the scrutiny.yaml file. Save and start up the container.
7. Test your notifications by issuing this command in the containers terminal:
   curl -X POST http://localhost:8080/api/health/notify
