— Add new check type: status-in
Similar to status-is except that the HTTP status can be one of a list, instead of just one fixed value.

Usecase: a Sympa server with CAS authentication set. Without a sympa_session cookie, you get a 302 status,
with it, you have a 200 status.

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"
status-in Check that the returned status code is in the list of codes you expect.
status-in:
- 200
- 302
body-contains Check that the returned body contains a given string. body-contains: "Hello world"

- domain: "https://example.org"
  paths:
    - path: "/"
      checks:
        - status-is: 200
        - body-contains: "Hello world"
    - path: "/foobar"
      checks:
        - status-in:
          - 200
          - 302

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.
