3. In the search box, enter the query that will generate the data and apply the relevant filters.  This is the same as writing a query and filters in the Discover section. In this example the  term ‘websphere’ is used to search for instances of ‘websphere’ in the log data. 4. In the left side pane, select the  data  tab, select  metrics , then set slice size to  Count . 5. In the buckets section, select  Split Slices  and set the following values: a. Set  Aggregation  to  Terms . b. Set  Field  to  kubernetes.namespace.keyword . c. Set  Order By  to  metric: Count . d. Set  Order  to  Descending  and  Size  to  10 . 6. Select the  Play  icon at the top of this pane and the pie chart should display with the data  from the search query. In this case, it will show the top 10 namespaces that contain the  highest number of logs generated by websphere containers. You can use the filters to  exclude certain namespaces, such as kube-system. The result should look similar to Figure 5-23. Save the visualization using the  Save  link at the  top of the page, as this will be used later to add to a dashboard. Explore the other visualizations available, ideally creating a few more as these can be used to  create a more meaningful Kibana Dashboard. The Kibana Dashboard page is where you can create, modify and view your own custom  dashboards where multiple visualizations can be combined on to a single page and filter them  by providing a search query or by selecting filters. Dashboards are useful for when you want  to get an overview of your logs and make correlations among various visualizations and logs. To create a new Dashboard, select the  +  icon, or  Create Visualization , if none exist. Select  Add Visualization , then select the visualizations created earlier you want to display in this  dashboard. From here, you further filter the data shown in the individual visualizations by  entering a search query, changing the time filter, or clicking on the elements within the  visualization. The search and time filters work just like they do in the Discover page, except  Dashboards Figure 5-23 Kibana visualization pie chart Chapter 5. Logging and monitoring  185
