 You can use the [LTSV log format](http://ltsv.org/), track TLS and cipher usage, and the whole parser is faster than
 ever. In one test on a system with SSD storage, the collector consistently parsed the logs for 200,000 requests in

 The LAMP stack is the "hello world" for deploying dynamic web applications. It's fast, flexible, and reliable, which
 means a developer or sysadmin won't go far in their career without interacting with the stack and its services.

 We love IoT and edge at Netdata, we also love machine learning. Even better if we can combine the two to ease the pain
 of monitoring increasingly complex systems.

-# Use host labels to organize systems, metrics, and alarms
-
-When you use Netdata to monitor and troubleshoot an entire infrastructure, whether that's dozens or hundreds of systems,
-you need sophisticated ways of keeping everything organized. You need alarms that adapt to the system's purpose, or
-whether the parent or child in a streaming setup. You need properly-labeled metrics archiving so you can sort,
-correlate, and mash-up your data to your heart's content. You need to keep tabs on ephemeral Docker containers in a
-Kubernetes cluster.
+# Using host labels to organize your metrics
+
+When you use Netdata to monitor and troubleshoot an entire infrastructure, you need sophisticated ways of keeping everything organized.
+
+Some of the scenarios that host labels can be extremely useful are:
+
+- You need alarms that adapt to the system's purpose
+- You need properly-labeled metrics archiving so you can sort, correlate, and mash-up your data to your heart's content.
+- You need to keep tabs on ephemeral Docker containers in a Kubernetes cluster.
 
 You need **host labels**: a powerful new way of organizing your Netdata-monitored systems. We introduced host labels in
 [v1.20 of Netdata](https://blog.netdata.cloud/posts/release-1.20/), and they come pre-configured out of the box.
