+
+### 🤔 The problem:
+
+Scrutiny offers a nice Docker package called "Omnibus" that can monitor HDDs attached to a Docker host with relative
+ease. Scrutiny can also be installed in a Hub-Spoke layout where Web interface, Database and Collector come in 3
+separate packages. The official documentation assumes that the spokes in the "Hub-Spokes layout" run Docker, which is
+not always the case. The third approach is to install Scrutiny manually, entirely outside of Docker.
+
+### 💡 The solution:
+
+This tutorial provides a hybrid configuration where the Hub lives in a Docker instance while the spokes have only
+Scrutiny Collector installed manually. The Collector periodically send data to the Hub. It's not mind-boggling hard to
+understand but someone might struggle with the setup. This is for them.
+
+### 🖥️ My setup:
+
+I have a Proxmox cluster where one VM runs Docker and all monitoring services - Grafana, Prometheus, various exporters,
+InfluxDB and so forth. Another VM runs the NAS - OpenMediaVault v6, where all hard drives reside. The Scrutiny Collector
+is triggered every 30min to collect data on the drives. The data is sent to the Docker VM, running InfluxDB.
+
+## Setting up the Hub
+
+![drawing-3-1671744714](https://user-images.githubusercontent.com/86809766/209230113-c954d834-521b-4555-bcd2-eb6b80f343be.png)
+
+The Hub consists of Scrutiny Web - a web interface for viewing the SMART data. And InfluxDB, where the smartmon data is
+stored.
+
+[🔗This is the official Hub-Spoke layout in docker-compose.](https://github.com/AnalogJ/scrutiny/blob/master/docker/example.hubspoke.docker-compose.yml)
+We are going to reuse parts of it. The ENV variables provide the necessary configuration for the initial setup, both for
+InfluxDB and Scrutiny.
+
+If you are working with and existing InfluxDB instance, you can forgo all the `INIT` variables as they already exist.
+
+The official Scrutiny documentation has a
+sample [scrutiny.yaml ](https://github.com/AnalogJ/scrutiny/blob/master/example.scrutiny.yaml)file that normally
+contains the connection and notification details but I always find it easier to configure as much as possible in the
+docker-compose.
+
+```yaml
+version: "3.4"
+
+networks:
+  monitoring: # A common network for all monitoring services to communicate into
+    external: true
+  notifications: # To Gotify or another Notification service
+    external: true
+
+services:
+  influxdb:
+    container_name: influxdb
+    image: influxdb:2.1-alpine
+    ports:
+      - 8086:8086

+    depends_on:
+      - influxdb
+    restart: unless-stopped
+    networks:
+      - notifications
+      - monitoring
+```
+
+A freshly initialized Scrutiny instance can be accessed on port 8080, eg. `192.168.0.100:8080`. The interface will be
+empty because no metrics have been collected yet.

+## Setting up a Spoke ***without*** Docker
+
+![drawing-3-1671744208](https://user-images.githubusercontent.com/86809766/209230155-386a8644-b506-497f-8245-0d24e15c9063.png)
+
+A spoke consists of the Scrutiny Collector binary that is run on a set interval via crontab and sends the data to the
+Hub. The official
+documentation [describes the manual setup of the Collector](https://github.com/AnalogJ/scrutiny/blob/master/docs/INSTALL_MANUAL.md#collector)
+- dependencies and step by step commands. I have a shortened version that does the same thing but in one line of code.
+
+```bash
+# Installing dependencies
+apt install smartmontools -y 
+
+# 1. Create directory for the binary
+# 2. Download the binary into that directory
+# 3. Make it exacutable
+# 4. List the contents of the library for confirmation
+mkdir -p /opt/scrutiny/bin && \
+curl -L https://github.com/AnalogJ/scrutiny/releases/download/v0.5.0/scrutiny-collector-metrics-linux-amd64 > /opt/scrutiny/bin/scrutiny-collector-metrics-linux-amd64 && \
+chmod +x /opt/scrutiny/bin/scrutiny-collector-metrics-linux-amd64 && \
+ls -lha /opt/scrutiny/bin
+```
+
+<p class="callout warning">When downloading Github Release Assests, make sure that you have the correct version. The provided example is with Release v0.5.0. [The release list can be found here.](https://github.com/analogj/scrutiny/releases) </p>
+
+Once the Collector is installed, you can run it with the following command. Make sure to add the correct address and
+port of your Hub as `--api-endpoint`.
+
+```bash
+/opt/scrutiny/bin/scrutiny-collector-metrics-linux-amd64 run --api-endpoint "http://192.168.0.100:8080"
+```
+
+This will run the Collector once and populate the Web interface of your Scrutiny instance. In order to collect metrics
+for a time series, you need to run the command repeatedly. Here is an example for crontab, running the Collector every
+15min.
+
+```bash
+# open crontab
+crontab -e
+
+# add a line for Scrutiny
+*/15 * * * * /opt/scrutiny/bin/scrutiny-collector-metrics-linux-amd64 run --api-endpoint "http://192.168.0.100:8080"
+```
+

+Setting up a remote Spoke in Docker requires you to split
+the [official Hub-Spoke layout docker-compose.yml](https://github.com/AnalogJ/scrutiny/blob/master/docker/example.hubspoke.docker-compose.yml)
+. In the following docker-compose you need to provide the `${API_ENDPOINT}`, in my case `http://192.168.0.100:8080`.
+Also all drives that you wish to monitor need to be presented to the container under `devices`.
+
+The image handles the periodic scanning of the drives.

+# Manual Windows Install
+
+This guide is specifically for people who are on a Windows machine using [WSL](https://learn.microsoft.com/en-us/windows/wsl/about) with Docker.
+
+Scrutiny is made up of three components: an influxdb Database, a collector and a webapp/api. Docker will be used for
+the influxdb and webapp/API, the collector component will be facilitated by [Windows Task Scheduler](https://learn.microsoft.com/en-us/windows/win32/taskschd/task-scheduler-start-page).
+
+> **NOTE:** If you are **NOT** using WSL with docker, then the easiest way to get started with [Scrutiny is the omnibus Docker image](https://github.com/AnalogJ/scrutiny#docker).
+
+## InfluxDB and Webapp/API (Docker)
+
+1. Copy the [example.hubspoke.docker-compose.yml](https://github.com/AnalogJ/scrutiny/blob/master/docker/example.hubspoke.docker-compose.yml) 
+file and delete the collector section near the bottom of the file.
+2. Run `docker-compose up -d` to verify that the DB and webapp are working correctly and once its completed, your webapp
+should be up and running but the dashboard will be empty (default location is `localhost:8080`)
+
+## Collector (Windows Task Scheduler)
+
+1. Download the latest `scrutiny-collector-metrics-windows-amd64.exe` from the [releases page](https://github.com/AnalogJ/scrutiny/releases) (under assets)
+2. On your windows host, open [Windows Task Scheduler](https://www.wikihow.com/Open-Task-Scheduler-in-Windows-10) as **Administrator**
+   1. In the **Start Menu** (Windows key), type `Task Scheduler` and then right click `Run as Administrator` to open
+3. On the status bar (under the `action` tab), click `Create Task...`
+4. A new window should open with the `General` Tab open, enter relevant information into the `Name` and `Description` fields
+   1. Under **Security Options** check:
+      1. **Run whether user is logged on or not**
+      2. **Run with highest privileges**
+5. Next, click the `Triggers` tab and then click `New...` (bottom left-hand side of the window)
+6. Here you can set how often you want this task to run, example settings are the following:
+   1. **Settings:**
+      1. `Daily`, start at `TODAYS_DATE` `12:00:00 AM`, Recur every `1` days,
+   2. **Advanced Settings:**
+      1. Repeat Task every: `1 hour` for a duration of `Indefinitely`
+      2. Stop task if it runs longer than: `30 minutes`
+   3. Click Ok when satisfied with your schedule
+   > **NOTE:** The above settings will trigger the task **every day at midnight** and then **run every hour after that** (modify as needed)
+7. Next, click the `Actions` tab and then click `New...` (bottom left-hand side of the window)
+   1. **Action Settings:**
+      1. In the **Program/Script** field, put: `scrutiny-collector-metrics-windows-amd64.exe`
+      2. In the **Add arguments (optional)** field, put: `run --api-endpoint "http://localhost:8080" --config collector.yaml`
+         > **NOTE:** 
+         > * Make sure that you put the correct port number (as specified in the docker-compose file) for the webapp (default is `8080`)
+         > * The `--config` param is optional and is not needed if you just want to use the default collector config, see 
+      [example.collector.yaml](https://github.com/AnalogJ/scrutiny/blob/master/example.collector.yaml) for more info on the collector config.
+      3. In the **Start in (optional)** field, put: FOLDER_PATH_TO_YOUR `scrutiny-collector-metrics-windows-amd64.exe` file
+          > **NOTE:** Must be exact and do not include `scrutiny-collector-metrics-windows-amd64.exe` in the path
+      4. Click Ok when finished
+8. Next, click the `Conditions` tab and make sure that everything is unchecked (unless you want to specify otherwise)
+9. Next, click the `Settings` tab and check everything except for the last checkbox
+   1. **Examples for the following settings:**
+      1. If the task fails, restart every: `5 minutes`
+      2. Attempt restart up to: `3` times
+      3. Stop the task if it runs longer than `1 hour`
+10. Next, once satisfied with everything, click Ok
+11. Then, find your newly created task (by its name) in the scheduler task list and then manually run it (right click it and then click `Run`)
+12. Finally, refresh your dashboard after a minute or two and your drive information should have populated the webapp dashboard.

 As such, passing devices to the Scrutiny collector container using `/dev/disk/by-id/`, `/dev/disk/by-label/`, `/dev/disk/by-path/` and `/dev/disk/by-uuid/`
 paths are unnecessary, unless you'd like to ensure the docker run command never needs to change.
 
+#### Force /dev/disk/by-id paths
+
+Since Scrutiny uses WWN under the hood, it really doesn't care about `/dev/sd*` vs `/dev/disk/by-id/`. The problem is the interaction between docker and smartmontools when using `--device /dev/disk/by-id` paths. 
+
+Basically Scrutiny offloads all device detection to smartmontools, which doesn't seem to detect devices that have been passed into the docker container using `/dev/disk/by-id` paths.
+
+If you must use "static" device references, you can map the host device id/uuid/wwn references to device names within the container:
