monitoring-nagios

A test harness to query multiple endpoints and roll up monitoring errors into a single alert for Nagios

Overview

The script queries application metadata containing a tag for the application and an array of endpoints. Each endpoint url executes is an application test returning an HTTP 200 status code upon success. If an endpoint fails, the test harness will roll up any errors based on the level defined in the metadata. Output is printed to stdout for Nagios, including the error message, tags, and level.

Usage
