In this chapter, we will cover other important features of Kibana, including Timelion and Dev Tools. We will cover how to use Timelion for time-series data and create different graphs by chaining different functions. Timelion provides us with flexibility, by means of which we can club data from different indices together to plot them on a graph. Using Timelion, we can get some interesting answers to questions that are difficult to answer—such as the difference between the data this Sunday and last Sunday—using default visualizations of Kibana. We can also compare the current data with older data, such as four-hour old data or one-week old data. We can plot on the basis of the moving average over a certain duration; it provides us with a smooth graph if the data plot is not easy to understand. Using Timelion trends, we can plot the trend of data...
