Follows this logic for verifying a connection to Elasticsearch:

Before the first API request:

  1. Make an API request to /, inspect the response:
  2. If call to / fails with 401 or 403 pass the check and show a warning (message will be linked later). This happens if the monitor permission missing for user. The subsequent checks must be ignored.
  3. If there's no version field or if the version field value is <6.0.0 raise an error.
  4. If there is a version field and it's >= 6.0.0 and <7.0.0:
    • If there is no tagline field or if the tagline field value isn't You know, for Search raise an error.
  5. If there is a version field and it's >=7.0.0 and <7.14.0:
    • If there is no tagline field or if the tagline field value isn't You know, for Search raise an error.
    • If there is no build_flavor field or if the build_flavor field value isn't default raise an error.
  6. If there is a version field and it's >=7.14.0:
    • If there is no X-Elastic-Product HTTP header in the response or if the X-Elastic-Product HTTP header value isn't Elasticsearch raise an error.
