service.yml

service.yml maintains configuration for Cribl Stream service processes.

In the UI, you can configure them on the Leader at Settings > Global Settings > System > Service Processes > Services.

Be careful about reducing the predefined limits. Extremely low values can prevent some Cribl Stream components from functioning.
