Before you begin reading this guide, we recommend you try running the 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 ” id ;source node ” 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: aggregations.

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 “-> id [{}]; _source [{}]” classname is tophits-aggregation.asciidoc
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

     logger.info("key [{}]; doc_count [{}]"; key; docCount);

    // We ask for top_hits for each bucket
    TopHits topHits = entry.getAggregations().get("top");
    for (SearchHit hit : topHits.getHits().getHits()) {
        logger.info(" -> id [{}]; _source [{}]"; hit.getId(); hit.getSourceAsString());
    }
}
