# Mike's Disk Usage Warn Thing # Mike's Disk Usage Warn Thing
This is a simple script that will emit a warning to stderr when your disk usage surpasses a configured threshold. StdErr output was chosen for its simplicity, and because it's very easy to configure a cron job to send you an email any time an error occurs. This is a simple script that will emit a warning to stderr when your disk usage surpasses a configured threshold.
Makes it easy to get emails fron crontab when your disk gets too full
## Requirements ## Requirements
* Python3 * pyenv
* Python *pyaml* module * pipenv inside
Example:
```sudo pip3 install pyaml```
* *logger* program, which should be on most distributions * *logger* program, which should be on most distributions
## Installation ## Installation
1. First, make sure you have python3 and pip3 installed 1. Install [pyenv](https://github.com/pyenv/pyenv)
2. Use pip3 to make sure you have the python module "pyaml" installed 2. cd to this repo's directory and run `$ pyenv install` to get the correct version of python
3. Create a configuration file somewhere. 3. Install pyenv with `$ pip install --upgrade pip pipenv`
4. Create a Crontab entry that will call this script with an argument "--config" followed by the path to your configuration file. 4. Initialize the pip environment with `$ pipenv install`
(examples found below) 5. Create a yaml configuration file somewhere.
6. Create a crontab entry that will call this script with an argument "--config" followed by the path to your configuration file.

### Example Call With Arguments ### Example Call With Arguments
Assuming you can invoke *Python 3* with the command ```python3```, here's a quick example using two configuration files: ```shell
cd /path/to/this/repo && pipenv run python main.py --config "/my/config/path-1" --config "/my/config/path-2"
```
python3 /path/to/disk-usage-warn --config "/my/config/path-1" --config "/my/config/path-2"
``` ```
## Example Crontab Entry ## Example Crontab Entry
As mentioned, the easiest way to use this script is with Crontabs. By default, cron jobs will send you an email any time a script outputs to stdout or stderr. Since this script will output lots of information onto stdout, and only output to stderr when a disk has become full, it's useful to redirect stdout to /dev/null, like so: As mentioned, the easiest way to use this script is with crontabs.
