elasticsearch - kibana 4.0中的比率趋势

Question

我有两个每日索引下的文件。两者都有 >=1 的计数字段。我想创建一个图表，显示这两个字段随时间聚合的比率趋势。数据将根据仪表板中选择的持续时间进行采样，例如：一天，每个样本为 10 分钟，这将分别对这两个字段求和并计算比率，然后显示为一个数据点。因此，在 24 小时内，图中将是 24*60 点。

我怎样才能在 Kibana 4 中实现相同的目标？

Answer 1

We tried something similar but turns out it is not possible in Kibana. As of now you can not plot a calculated field based on two different fields in Kibana.
To workaround this, we implemented a plugin that modifies data before it is pumped to elastic search. So we carried out calculations in that plugin. Also, the plugin periodically pumps data to elastic search so kibana gets the latest values
