Kibana 简明教程

Kibana - Create Dashboard

在之前的章节中，我们已经看到了如何创建垂直条形、水平条形、饼图等形式的可视化。在本章中，让我们学习如何将它们组合成仪表板。仪表板是由您创建的可视化集合，因此您可以同时查看它们。

In our previous chapters, we have seen how to create visualization in the form of vertical bar, horizontal bar, pie chart etc. In this chapter, let us learn how to combine them together in the form of Dashboard. A dashboard is collection of your visualizations created, so that you can take a look at it all together at a time.

Getting Started with Dashboard

要在 Kibana 中创建仪表板，请单击“仪表板”选项，如下所示 −

To create Dashboard in Kibana, click on the Dashboard option available as shown below −

现在，单击“创建新仪表板”按钮，如下所示。它将带我们到如下所示的屏幕 −

Now, click on Create new dashboard button as shown above. It will take us to the screen as shown below −

请注意，到目前为止，我们还没有创建任何仪表板。顶部有选项，我们可以在其中保存、取消、添加、选项、共享、自动刷新，还可以更改时间以获取仪表板上的数据。我们将单击上面显示的“添加”按钮来创建一个新仪表板。

Observe that we do not have any dashboard created so far. There are options at the top where we can Save, Cancel, Add, Options, Share, Auto-refresh and also change the time to get the data on our dashboard. We will create a new dashboard, by clicking on the Add button shown above.

Add Visualization to Dashboard

当我们单击“添加”按钮（左上角）时，它会显示我们创建的可视化，如下所示 −

When we click the Add button (top left corner), it displays us the visualization we created as shown below −

选择您要添加到仪表板的可视化。我们将选择前三个可视化，如下所示 −

Select the visualization you want to add to your dashboard. We will select the first three visualizations as shown below −

这是它们在屏幕上同时显示的方式 −

This is how it is seen on the screen together −

因此，作为用户，您能够获得我们上传的数据的总体详细信息——按国家/地区划分，包括国家/地区名称、区域名称、面积和人口字段。

Thus, as a user you are able to get the overall details about the data we have uploaded – country wise with fields country-name, regionname, area and population.

所以现在我们知道了所有可用的区域，按降序排列的每个国家的人口最多、面积最大的区域等等。

So now we know all the regions available, the max population country wise in descending order, the max area etc.

这只是我们上传的示例数据可视化，但在实际中，跟踪您业务的详细信息变得非常容易，例如您有一个每月或每天获得数百万次点击的网站，您想要跟踪每天、每小时、每分钟、每秒完成的销售额，并且如果您有 ELK 堆栈，Kibana 可以按您需要的方式每小时、每分钟、每秒在您眼前显示您的销售可视化。它会显示实际世界中正在发生的实时数据。

This is just the sample data visualization we uploaded, but in real world it becomes very easy to track the details of your business like for example you have a website which gets millions of hits monthly or daily, you want to keep a track on the sales done every day, hour, minute, seconds and if you have your ELK stack in place Kibana can show you your sales visualization right in front of your eyes every hour, minute, seconds as you want to see. It displays the real time data as it is happening in the real world.

总的来说，Kibana 在按天、按小时或每分钟提取有关您业务交易的准确详细信息方面发挥着非常重要的作用，因此公司知道进展如何。

Kibana, on the whole, plays a very important role in extracting the accurate details about your business transaction day wise, hourly or every minute, so the company knows how the progress is going on.
