When my application is running on multiple hosts (Let's assume multiple physical servers), how will installing a single agent on a single host help analyze the entire environment?&nbsp;</P> <P>2. Do we need to install the agent on every host part of the entire application?</P> <P>3. Installing a single agent on a host part of a single application can give me access to all other applications running on my environment?</P> <P>4. If yes, how is that possible since it requires authentication and authorization each time the agent scan the environment?</P> Tue, 14 Feb 2023 12:22:03 GMT https://community.dynatrace.com/t5/Open-Q-A/OneAgent-Installation/m-p/187857#M24601 sk00595545 2023-02-14T12:22:03Z https://community.dynatrace.com/t5/Open-Q-A/OneAgent-Installation/m-p/187939#M24602 <P>1.
