Chapter 9: Managing Data Onboarding with Elastic Agent

In the previous chapter, we explored some of the visualization tools available to users on Kibana to explore, interrogate, and understand different types of data. We also looked at how solution-specific applications on Kibana enable the different search, security, and observability use cases.

If your goal is to build in-depth security or observability use cases from your data (such as detecting errors in your environment before they impact user experience, or stopping security threats before they can disrupt your business), you need to onboard and ingest data from multiple layers of your technology stack to maximize your visibility. For example, if you're monitoring a simple three-tier web application, you would want to collect the following:

• HTTP request/error logs from your frontend web server
• Success/error logs and metrics/traces from your application
• Metrics and error logs from your database layer
