## Compatibility

- NetBox `4.6.5`
- Python `>=3.11`

## Installation

All paths assume a standard installation under `/opt/netbox`.

### 1. Install the package

```bash
/opt/netbox/venv/bin/pip install --upgrade --force-reinstall \
  "git+https://git.mrblake.cc/MrBlake/NetBox-SLM.git@master"
```

For reproducible production installs, replace `master` with a release tag or a
full commit ID.

### 2. Add the plugin to `local_requirements.txt`

This makes `upgrade.sh` reinstall the plugin automatically on every NetBox upgrade:

```bash
grep -qxF "git+https://git.mrblake.cc/MrBlake/NetBox-SLM.git@master" /opt/netbox/local_requirements.txt \
  || echo "git+https://git.mrblake.cc/MrBlake/NetBox-SLM.git@master" | sudo tee -a /opt/netbox/local_requirements.txt
```

If the repository is private, the NetBox server needs a read-only deploy token
or an SSH key. Do not store credentials in `local_requirements.txt`.

### 3. Enable the plugin

In `/opt/netbox/netbox/netbox/configuration.py`:

```python
PLUGINS = [
    "netbox_slm",
]
```

If other plugins are already configured, add `netbox_slm` to the existing list.
No `PLUGINS_CONFIG` is required for standard operation.

### 4. Apply migrations, collect static files, restart

```bash
cd /opt/netbox/netbox
/opt/netbox/venv/bin/python manage.py migrate netbox_slm
/opt/netbox/venv/bin/python manage.py collectstatic --no-input
sudo systemctl restart netbox netbox-rq
```

Check the installed version:

```bash
/opt/netbox/venv/bin/pip show netbox-slm
```

## Update

```bash
/opt/netbox/venv/bin/pip install --upgrade --force-reinstall \
  "git+https://git.mrblake.cc/MrBlake/NetBox-SLM.git@master"

cd /opt/netbox/netbox
/opt/netbox/venv/bin/python manage.py migrate netbox_slm
/opt/netbox/venv/bin/python manage.py collectstatic --no-input
sudo systemctl restart netbox netbox-rq
```

`--force-reinstall` makes pip pick up branch changes even if the package
version has not been bumped.

When NetBox itself is upgraded, `upgrade.sh` reinstalls the plugin from
`local_requirements.txt` and runs migrations and `collectstatic`:

```bash
sudo /opt/netbox/upgrade.sh
sudo systemctl restart netbox netbox-rq
```

## Uninstall

1. Remove `"netbox_slm"` from `PLUGINS`.
2. Remove the line from `/opt/netbox/local_requirements.txt`.
3. Uninstall the package and restart NetBox:

```bash
/opt/netbox/venv/bin/pip uninstall netbox-slm
sudo systemctl restart netbox netbox-rq
```

The plugin's database tables are not dropped automatically.

## Usage

### Expiry notifications

Notifications are enabled by default for licenses with an expiry date. The
default reminders are one month and one week before expiry. Per license, an
additional custom warning period can be set or the defaults can be disabled.

Recipients decide themselves whether they are notified: sales, the responsible
technician or other users open the license and click the NetBox **Subscribe**
action (**Unsubscribe** stops it). Without subscribers no message is sent.

A NetBox notification is always created. If **E-mail notifications** is enabled
on the license, the plugin also sends an e-mail to the address stored in the
user account; NetBox SMTP must be configured for this.

Enabling e-mail delivery can only be changed by administrators or users with
the permission `netbox_slm.manage_softwarelicense_email_notifications`. SMTP
credentials are maintained only in the NetBox server configuration and are not
visible in the plugin.

The check runs once a day as a NetBox system job. Once the first configured
reminder date is reached, subscribers are notified on every job run up to and
including the expiry date. The NetBox RQ worker must run with scheduler support,
which is the default for a standard NetBox installation with `rqworker`.
