Checks

At its core, argos runs checks and return the results to the service. Here are the implemented checks, with a description of what they do and how to configure them.

Simple checks

These checks are the most basic ones. They simply check that the response from the service matches what you expect.

Check	Description	Configuration
status-is	Check that the returned status code matches what you expect.	status-is: "200"
body-contains	Check that the returned body contains a given string.	body-contains: "Hello world"

  paths:
    - path: "/"
      checks:
        - status-is: 200
        - body-contains: "Hello world"

SSL certificate expiration

Checks that the SSL certificate will not expire soon. You need to define the thresholds in the configuration, and set the on-check option to enable the check.
