         to operate normally; except all read operations will be blocked.

        if (licenseState.isStatsAndHealthAllowed() == false && LICENSE_EXPIRATION_ACTION_MATCHER.test(action)) {
            logger.error("blocking [{}] operation due to expired license. Cluster health; cluster stats and indices stats \n" +
                    "operations are blocked on license expiration. All data operations (read and write) continue to work. \n" +
                    "If you have a new license; please update it. Otherwise; please reach out to your support contact."; action);
            throw LicenseUtils.newComplianceException(XPackField.SECURITY);
