"Sits next to" can mean that it's in the same namespace as your application, if you're deploying your app to a k8s cluster, or even deployed as a sidecar to the app in k8s.
The "or on the same host" means that if you're deploying your app on a VM, you can deploy your Collector and your app on the same VM.
You say: “In agent mode, the Collector sits next to the application or on the same host as the application.”
What does “sits next to” mean, and the OR suggests these are two different approaches so what are they in more detail?
