Hi, the Blackbox exporter doesn't do full-string matching for these regexes, but substring matching, so it also matches if the body contains "OK" anywhere (which is true for "NOK"). Try '^OK$` instead?
Also, in case your HTTP endpoint returns a status code other than 2xx, you will have to set the "valid_status_codes" list to the allowed ones (it defaults to 2xx).
