+## Manual Installation (without-Docker)
+
+While the easiest way to get started with [Scrutiny is using Docker](https://github.com/AnalogJ/scrutiny#docker),
+it is possible to run it manually without much work. You can even mix and match, using Docker for one component and
+a manual installation for the other.
+
+See [docs/INSTALL_MANUAL.md](docs/INSTALL_MANUAL.md) for instructions.

 # Configuration
-We support a global YAML configuration file that must be located at /scrutiny/config/scrutiny.yaml
+We support a global YAML configuration file that must be located at `/scrutiny/config/scrutiny.yaml`

 Check the [example.scrutiny.yml](example.scrutiny.yaml) file for a fully commented version.

+## Notifications
+
+Scrutiny supports sending SMART device failure notifications via the following services:
+- Custom Script (data provided via environmental variables)
+- Email
+- Webhooks
+- Discord
+- Gotify
+- Hangouts
+- IFTTT
+- Join
+- Mattermost
+- Pushbullet
+- Pushover
+- Slack
+- Teams
+- Telegram
+- Tulip
+
+Check the `notify.urls` section of [example.scrutiny.yml](example.scrutiny.yaml) for more information and documentation for service specific setup.
+
+### Testing Notifications
+
+You can test that your notifications are configured correctly by posting an empty payload to the notifications health check API.
+
+```
+curl -X POST http://localhost:8080/api/health/notify
+```
+
+# Debug mode & Log Files
+Scrutiny provides various methods to change the log level to debug and generate log files.
+
+## Web Server/API
+
+You can use environmental variables to enable debug logging and/or log files for the web server:
+
+```
+DEBUG=true
+SCRUTINY_LOG_FILE=/tmp/web.log
+```
+
+You can configure the log level and log file in the config file:
+
+```
+log:
+  file: '/tmp/web.log'
+  level: DEBUG
+```
+
+Or if you're not using docker, you can pass CLI arguments to the web server during startup:
+
+```
+scrutiny start --debug --log-file /tmp/web.log
+```
+
+## Collector
+
+You can use environmental variables to enable debug logging and/or log files for the collector:
+
+```
+DEBUG=true
+COLLECTOR_LOG_FILE=/tmp/collector.log
+```
+
+Or if you're not using docker, you can pass CLI arguments to the collector during startup:
+
+```
+scrutiny-collector-metrics run --debug --log-file /tmp/collector.log
+```

+# Manual Install

+While the easiest way to get started with [Scrutiny is using Docker](https://github.com/AnalogJ/scrutiny#docker),
+it is possible to run it manually without much work. You can even mix and match, using Docker for one component and
+a manual installation for the other.
+
+Scrutiny is made up of two components: a collector and a webapp/api. Here's how each component can be deployed manually.
+
+> Note: the `/opt/scrutiny` directory is not hardcoded, you can use any directory name/path.
+
+## Webapp/API
+
+### Dependencies
+
+Since the webapp is packaged as a stand alone binary, there isn't really any software you need to install other than `glibc`
+which is included by most linux OS's already.
+
+
+### Directory Structure
+
+Now let's create a directory structure to contain the Scrutiny files & binary.
+
+```
+mkdir -p /opt/scrutiny/config
+mkdir -p /opt/scrutiny/web
+mkdir -p /opt/scrutiny/bin
+```
+
+### Config file
+
+While it is possible to run the webapp/api without a config file, the defaults are designed for use in a container environment,
+and so will need to be overridden. So the first thing you'll need to do is create a config file that looks like the following:
+
+```
+# stored in /opt/scrutiny/config/scrutiny.yaml
+
+version: 1
+
+web:
+  database:
+    # The Scrutiny webapp will create a database for you, however the parent directory must exist.
+    location: /opt/scrutiny/config/scrutiny.db
+  src:
+    frontend:
+      # The path to the Scrutiny frontend files (js, css, images) must be specified.
+      # We'll populate it with files in the next section
+      path: /opt/scrutiny/web
+```
+
+> Note: for a full list of available configuration options, please check the [example.scrutiny.yaml](https://github.com/AnalogJ/scrutiny/blob/master/example.scrutiny.yaml) file.
+
+### Download Files
+
+Next, we'll download the Scrutiny API binary and frontend files from the [latest Github release](https://github.com/analogj/scrutiny/releases).
+The files you need to download are named:
+
+- **scrutiny-web-linux-amd64** - save this file to `/opt/scrutiny/bin`
+- **scrutiny-web-frontend.tar.gz** - save this file to `/opt/scrutiny/web`
+
+### Prepare Scrutiny
+
+Now that we have downloaded the required files, let's prepare the filesystem.
+
+```
+# Let's make sure the Scrutiny webapp is executable.
+chmod +x /opt/scrutiny/bin/scrutiny-web-linux-amd64
+
+# Next, lets extract the frontend files.
+cd /opt/scrutiny/web
+tar xvzf scrutiny-web-frontend.tar.gz --strip-components 1 -C .
+
+# Cleanup
+rm -rf scrutiny-web-frontend.tar.gz
+```
+
+### Start Scrutiny Webapp
+
+Finally, we start the Scrutiny webapp:
+
+```
+/opt/scrutiny/bin/scrutiny-web-linux-amd64 start --config /opt/scrutiny/config/scrutiny.yaml
+```
+
+The webapp listens for traffic on `http://0.0.0.0:8080` by default.
+
+
+## Collector
+
+### Dependencies
+
+Unlike the webapp, the collector does have some dependencies:
+
+- `smartctl`, v7+
+- `cron` (or an alternative process scheduler)
+
+Unfortunately the version of `smartmontools` (which contains `smartctl`) available in some of the base OS repositories is ancient.
+So you'll need to install the v7+ version using one of the following commands:
+
+- **Ubuntu:** `apt-get install -y smartmontools=7.0-0ubuntu1~ubuntu18.04.1`
+- **Centos8:**
+    - `dnf install https://extras.getpagespeed.com/release-el8-latest.rpm`
+    - `dnf install smartmontools`
+- **FreeBSD:** `pkg install smartmontools`
+
+### Directory Structure
+
+Now let's create a directory structure to contain the Scrutiny collector binary.
+
+```
+mkdir -p /opt/scrutiny/bin
+```
+
+
+### Download Files
+
+Next, we'll download the Scrutiny collector binary from the [latest Github release](https://github.com/analogj/scrutiny/releases).
+The file you need to download is named:
+
+- **scrutiny-collector-metrics-linux-amd64** - save this file to `/opt/scrutiny/bin`
+
+
+### Prepare Scrutiny
+
+Now that we have downloaded the required files, let's prepare the filesystem.
+
+```
+# Let's make sure the Scrutiny collector is executable.
+chmod +x /opt/scrutiny/bin/scrutiny-collector-metrics-linux-amd64
+```
+
+### Start Scrutiny Collector, Populate Webapp
+
+Next, we will manually trigger the collector, to populate the Scrutiny dashboard:
+
+```
+/opt/scrutiny/bin/scrutiny-collector-metrics-linux-amd64 run --api-endpoint "http://localhost:8080"
+```
+
+### Schedule Collector with Cron
+
+Finally you need to schedule the collector to run periodically.
+This may be different depending on your OS/environment, but it may look something like this:
+
+```
+# open crontab
+crontab -e
+
+# add a line for Scrutiny
+*/15 * * * * . /etc/profile; /opt/scrutiny/bin/scrutiny-collector-metrics-linux-amd64 run --api-endpoint "http://localhost:8080"
+```

Jason Kulatunga	b44ef5cb9c	adding support for a collecto config file. /scrutiny/config/collector.yaml Adding ability to specify host identifier (label), that is updated on every collector run. Can be specified by `host-id` CLI or `COLLECTOR_HOST_ID` env var. Created a config class, interface and associated tests. Created a "TransformDetectedDrives" function, that will allow users to insert drives not detected by Smarctl --scan, ignore drives that they dont want, and override smartctl device type. Added Upsert functionality when registering devices. Replaced "github.com/jinzhu/gorm" with "gorm.io/gorm" (ORM location moved, was using incorrect lib url) Removed machineid library.	2020-10-07 21:54:29 -06:00
