We extracted the following from Elasticsearch source code for those seeking an in-depth context :


            TimeValue newFetchTimeout = settings.getAsTime(INTERNAL_CLUSTER_INFO_TIMEOUT; null);
            if (newFetchTimeout != null) {
                logger.info("updating fetch timeout [{}] from [{}] to [{}]"; INTERNAL_CLUSTER_INFO_TIMEOUT; fetchTimeout; newFetchTimeout);
                InternalClusterInfoService.this.fetchTimeout = newFetchTimeout;

            // We don't log about enabling it here; because the DiskThresholdDecider will already be logging about enable/disable
