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.
To create Dashboard in Kibana, click on the Dashboard option available as shown below −
Now, click on Create new dashboard button as shown above. It will take us to the screen as shown below −
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.
When we click the Add button (top left corner), it displays us the visualization we created as shown below −
Select the visualization you want to add to your dashboard. We will select the first three visualizations as shown below −
This is how it is seen on the screen together −
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.
So now we know all the regions available, the max population country wise in descending order, the max area etc.
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.
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.
You can save your dashboard by using the save button at the top.
There is a title and description where you can enter the name of the dashboard and a short description which tells what the dashboard does. Now, click on Confirm Save to save the dashboard.
At present you can see the data shown is of Last 15 minutes. Please note this is a static data without any time field so the data displayed will not change. When you have the data connected to real time system changing the time, will also show the data reflecting.
