Hi. The short answer is, that the data is not collected.
Long answer is based on which type of disablement we are discussing.
* Disabling Host monitoring makes OneAgent enter disabled state. It will not do anything, except periodically checking for configuration updates (to see if it was not enabled again).
* Disabling monitoring of individual PGs does two things. First, it will disable injection for given PG (so given specialized agent is not even present for newly started processes) and it will make already injected specialized agents go into disabled state (see previous point). Please note, that this is only related to metrics collected by specialized agents, the base OS-level metrics will still be collected for such process.
*Disabling monitoring of given Application changes the behavior of Webserver agent, so that the sensors to provide measurements will not get injected into http responses. Again - this will not affect the per PGI measurements.
