Before you dig into reading this guide, have you tried asking OpsGPT what this log means? You’ll receive a customized analysis of your log.

Try OpsGPT now for step-by-step guidance and tailored insights into your Elasticsearch operation.

Briefly, this error occurs when Elasticsearch is automatically adjusting the flush threshold period due to high indexing or search load. This is a self-regulating mechanism to prevent data loss and maintain performance. To resolve this, you can manually set the flush threshold in the Elasticsearch settings. However, be cautious as setting it too low can lead to excessive flushing and degrade performance. Alternatively, you can optimize your indexing or search operations to reduce the load on the Elasticsearch cluster.

Log Context

Log “updating flush_threshold_period from [{}] to [{}]” classname is TranslogService.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                 logger.info("updating flush_threshold_size from [{}] to [{}]"; TranslogService.this.flushThresholdSize; flushThresholdSize);
                TranslogService.this.flushThresholdSize = flushThresholdSize;
            }
            TimeValue flushThresholdPeriod = settings.getAsTime(INDEX_TRANSLOG_FLUSH_THRESHOLD_PERIOD; TranslogService.this.flushThresholdPeriod);
            if (!flushThresholdPeriod.equals(TranslogService.this.flushThresholdPeriod)) {
                logger.info("updating flush_threshold_period from [{}] to [{}]"; TranslogService.this.flushThresholdPeriod; flushThresholdPeriod);
                TranslogService.this.flushThresholdPeriod = flushThresholdPeriod;
            }
            TimeValue interval = settings.getAsTime(INDEX_TRANSLOG_FLUSH_INTERVAL; TranslogService.this.interval);
            if (!interval.equals(TranslogService.this.interval)) {
                logger.info("updating interval from [{}] to [{}]"; TranslogService.this.interval; interval);
