6 Customizing event sources 6.1 Introduction Event sources are computers that contain the logs to be processed by GFI EventsManager. In GFI EventsManager, these event sources are organized into specific computer groups. You can create custom event source groups tailored on your network infrastructure or you can use the pre-defined groups that ship by default with this product. GFI EventsManager ships with two distinct event source groups namely ‘Event Sources Groups’ and ‘Database Server Groups’. You can use default groups to distinctively organize and configure the servers, workstations and laptops that will be monitored by GFI EventsManager; or you can choose to group target computers that have specific roles on your network such as web Servers, file servers and data servers.
