|Title||The "Check_MK Discovery" service is executed in a much more performant way|
|Check_MK Edition||Check_MK Enterprise Edition (CEE)|
|Level||2 - Prominent Change|
|Compatibility||Compatible - no manual interaction needed|
The "Check_MK Discovery" check was executed as active check, initializing the whole python interpreter, check_mk and the whole check_mk configuration for each check, just to perform an inventory check for a single host.
Now the "Check_MK Discovery" service also uses the permanently running Check_MK Helper processes just like the regular Check_MK service which results in a big performanc boosts for environments with a large number of hosts using the "Check_MK Discovery" service.
