Log Context

Log “Failed to get datafeed stats to include in ML usage” classname is MachineLearningUsageTransportAction.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

        dataframeAnalyticsStatsRequest.setPageParams(new PageParams(0; 10_000));
        ActionListener datafeedStatsListener = ActionListener.wrap(response -> {
            addDatafeedsUsage(response; datafeedsUsage);
            client.execute(GetDataFrameAnalyticsStatsAction.INSTANCE; dataframeAnalyticsStatsRequest; dataframeAnalyticsStatsListener);
        }; e -> {
            logger.warn("Failed to get datafeed stats to include in ML usage"; e);
            client.execute(GetDataFrameAnalyticsStatsAction.INSTANCE; dataframeAnalyticsStatsRequest; dataframeAnalyticsStatsListener);
        });

        // Step 1. Extract usage from jobs stats and then request stats for all datafeeds
        GetDatafeedsStatsAction.Request datafeedStatsRequest = new GetDatafeedsStatsAction.Request(Metadata.ALL);
