Before you begin reading this guide, we recommend you run Elasticsearch Error Check-Up which can resolve issues that cause many errors.

This guide will help you check for common problems that cause the log ” Updated datafeed ” to appear. It’s important to understand the issues related to the log, so to get started, read the general overview on common issues and tips related to the Elasticsearch concepts: plugin.

Advanced users might want to skip right to the common problems section in each concept or try running the Check-Up which analyses ES to pinpoint the cause of many errors and provides suitable actionable recommendations how to resolve them (free tool that requires no installation).

Log Context

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

                     private volatile DatafeedConfig updatedDatafeed;

                    protected PutDatafeedAction.Response newResponse(boolean acknowledged) {
                        if (acknowledged) {
                            logger.info("Updated datafeed [{}]"; request.getUpdate().getId());
                        return new PutDatafeedAction.Response(updatedDatafeed);
