# Prometheus Cron Exporter

An exporter built to report various metrics of cron jobs by parsing the syslog
files writen to by crond

## Installation

### Using the repository 

1. Run `$ yarn` to install dependencies
2. Run the tests with `$ yarn test`
3. Build the exporter with `$ yarn build`
4. Run `$ node ./build/index.js`

### Via npm package

1. Run `$ yarn global add @skroutz/cron-exporter`
2. The binary should be installed under `$ <PATH_TO_YOUR_NODE_MODULES>/.bin/cron-exporter`

## Configuration

The exporter can be configured using environment variables

| Variable   | Description | Default Value |
| ---------- | ----------- | ------------- |
| `CE_HOST`  | The host that the app should respond to | undefined |
| `CE_PORT`  | The port to run the exporter | 6748 |
| `CE_PREFIX` | Metric prefix for prometheus | '' |
| `CE_APPEND_TIMESTAMP` | Wether the metric should also be timestamped | true |
| `CE_ENDPOINT` | Endpoint that the exporter responds to | '/metrics' |
| `CE_LOGFILE` | Logfile to parse data from | '/var/log/cron.log' |
| `CE_COLLECT_INTERVAL` | Interval of the collecting process in milliseconds | 5 |
