Question

这是能够流利地写入我的日志的记录。

var cols = 5;
var rows = 5;

function connectedPoints(point) {
  var connectedPoints = [];

  // First test if the point is on an edge
  var topEdge = point/cols < 1;
  var leftEdge = point%cols == 0;
  var rightEdge = point%cols == cols-1;
  var bottomEdge = point/cols >= rows-1;

  // Add points that are above the point
  if (!topEdge) {
    if (!leftEdge) {
      connectedPoints.push(returnIfNotNegative(point-cols-1));
    }

    connectedPoints.push(returnIfNotNegative(point-cols));

    if (!rightEdge) {
      connectedPoints.push(returnIfNotNegative(point-cols+1));
    }
  }

  // Add points that are to the left or right of the point
  if (!leftEdge) {
    connectedPoints.push(returnIfNotNegative(point-1));
  }
  if (!rightEdge) {
    connectedPoints.push(returnIfNotNegative(point+1));
  }

  // Add points that are below the point
  if (!bottomEdge) {
    if (!leftEdge) {
      connectedPoints.push(returnIfNotNegative(point+cols-1));
    }

    connectedPoints.push(returnIfNotNegative(point+cols));

    if (!rightEdge) {
      connectedPoints.push(returnIfNotNegative(point+cols+1));
    }
  }

  console.log(connectedPoints);
}

function returnIfNotNegative(point) {
  if (point < 0) {
    return null;
  }
  return point;
}

connectedPoints(0);

日期时间是流利的时间键。我如何将这段时间放在json字符串中？

我的朋友帮助了我。他使用了这个流畅的插件：

http://docs.fluentd.org/articles/filter-plugin-overview

这是配置：

<filter trackLog>
   type record_modifier

        <record>
         fluentd_time ${Time.now.strftime("%Y-%m-%d %H:%M:%S")}
        </record>
 </filter>


<match trackLog>
  type record_modifier
  tag trackLog.finished

</match>

<match trackLog.finished>
 type webhdfs
 host localhost
 port 50070
 path /data/trackLog/%Y%m%d_%H
 username hdfs
 output_include_tag false
 remove_prefix trackLog.finished

 output_include_time false
 buffer_type file
 buffer_path /mnt/ramdisk/trackLog
 buffer_chunk_limit 4m
 buffer_queue_limit 50
 flush_interval 5s
</match>
