nodejs-health-check

NOT A STATE OF THE ART CODE, I'M JUST MESSING AROUND!

A health check ping using node.js that notifies a e-mail address when the url is down or no responding 200 codes for a specific set of parameters.

Instructions

Create a configuration JSON

You can use the config-example.json file as an example to you configuration JSON.

In the JSON, you need to fill the SMTP info (host, port, user and password). There is 2 ways to do it:

1. One smtp_settings for all apps, right on the root of the object;

2. One smtp_settings for each app;

App's smtp_settings will always override root's smtp_settings.

You also need to fill the array targets with objects containing the following properties:

• url: The URL you want to monitor using http:// or https://;
• method: The HTTP method you want to use. If nothing is provided, GET will be used;
• app_name: This name will be used to the email's subject and content;
• report_email: The email to which the report will be sent;
• body: If the response should have any specific body, fill it here.

Place the call in the crontab of a server and that's it!

Setting your configuration

There are 3 ways to inject your JSON configuration to the app:

1. Set an environment variable HEALTH_CHECK_CONFIG_FILE with the path to the file;

2. Set an environment variable HEALTH_CHECK_CONFIG with the whole configuration JSON;

3. Set an environment variable HEALTH_CHECK_CONFIG_URL with and URL to a plain text configuration JSON, the app will request it via GET and parse it;

Run

Simple as $ npm start.
