Kibana: Analyzing Data

Image Modified

Scheer PAS uses Kibana to view, filter and search the platform log s for all services.

Kibana is an open source analytics and visualization tool designed to work with Elasticsearch. With Kibana you can search, view, and interact with data stored in Elasticsearch indices. You can perform advanced data analysis and visualize your data in a variety of charts, tables, and maps.

Tip

For detailed information on Kibana, its features and how to use them, refer to the Official Kibana Documentation. Please note that Scheer PAS does not use the regular Elasticsearch/Kibana installation but the OpenDistro version. Some Kibana features may not be available in the OpenDistro version.

Please note that the official documentation may vary according to different versions of the tool.

Before consulting the documentation check your Kibana version. It is displayed if you open the help menu  where you can also find a direct link to the official documentation.

Creating an Index Pattern

Kibana needs to knows which Elasticsearch indices contain the data you want to analyze. So you have to create an index pattern in Kibana first to make sure that data is available. If your Kibana is empty and does not contain an index pattern yet, Kibana asks you to create one. You need to do this only once after the first login, then all users with Kibana permission can view the logs.

    Click here to set a time range for the data you want to inspect.
  3. Sidebar:
    Use the sidebar to select your index pattern and to access the list of available fields.
  4. Time Histogramm:
    Shows the time range of the displayed data.
    To view the count of documents for a given time, drag the mouse over the histogram.
  5. Documents Table:

To inspect logs of Scheer PAS Node.js services, you can for example select the following settings to display:

  • timestamp (displayed by default)
  • service (= name of the service)
  • level (= log level)
  • message (= log message)
  • context.user.loginId (= login name of the user)
  • context.request.uuid (= UUID of the request)

Once you have created such a query, you are also able to save it for further use, for example in a dashboard.

Creating Dashboards

Kibana also offers the possibility to create your own dashboards.

You can add a variety of different panels to inspect and visualize your data, for example area charts, bar and line charts, tree and heat maps, metrics, data tables and many more.

Choose option Dashboard in the sidebar to start.

If no dashboards are available, you are asked to create your first dashboard. For example, use a query saved in Discover to insert it as block in your dashboard.

Tip

Refer to page Dashboard in the Official Kibana Documentation for detailed information how to create a dashboard.

If you have already created some dashboards, the available dashboards are displayed.

Use the list to open, edit or delete your dashboards.
