## Usage
Install the app first
```
npm i -g @toolisticon/ssl-hostinfo-prometheus-exporter
```
This nodejs application assumes that you define a list of urls to check via environment variables:
```
export URLS_TO_CHECK=app1.sample.com,app2.sample.com
ssl-hostinfo-prom
```
## Sample Values
The metrics are available via via localhost:9000 :
```

```
[Here](https://grafana.com/dashboards/10144) you'll find a sample dashboard.
## Configuration
You can override the config via environment variables:
```
URLS_TO_CHECK: // list of urls
SERVER_PORT: // set desired port for prometheus endpoint, defaults to 9000
CRON: // set cron pattern, default is '0 0 * * * *',
LOG_LEVEL: // set log level, default is 'ERROR' ('INFO' outputs details info),
CONSOLE_LOG: // set to true to omit logging to file, otherwise logs will be written to `logs` dir
```
Sample:
```
URLS_TO_CHECK=url1.sample.com,url2.sample.com:8443 LOG_LEVEL=INFO CONSOLE_LOG=true node app.js
```
Will produce the following output:
```
{"pid":65072,"msg":"[log4bro] Logger is: in-prod=false, in-docker:true, level=DEBUG, skipDebug=false","loglevel":"INFO","loglevel_value":30,"@timestamp":"2019-04-02T13:56:20.443Z","host":"MPB-M1.local","log_type":"application","application_type":"service"}

```
And
```
URLS_TO_CHECK=url1.sample.com,url2.sample.com LOG_LEVEL=INFO node app.js
```
creates this output:
```

```
and the logs in JSON format within the directy `logs`
>NOTE: You can omit the port, it will default to 443.
## Troubleshooting
TBD
## Development
### Usage as library
The package can be also used as a dependency:
```
npm i @toolisticon/ssl-hostinfo-prometheus-exporter
```
In your app you can use then the api:
```
const updateRoutesInfo = require('@toolisticon/ssl-hostinfo-prometheus-exporter').updateRoutesInfo;
const startPrometheusListener = require('@toolisticon/ssl-hostinfo-prometheus-exporter').startPrometheusListener;
// trigger one update immediatly
triggerUpdate();
startPrometheusListener();
```
### Debug
To debug run the following command:
```
node --inspect-brk index.js
```
To debug unit tests:
```
npm run test:debug
```
