Determine the Collector and Connector plug-ins installed in the system by clicking Plug-ins > Catalog. You can see the plug-ins versions and other metadata, which helps you determine whether you have the latest version of a plug-in. If you want a later version of a plug-in, download the plug-in from the Sentinel Plug-ins Web site.
For information about editing Collectors that are already included in Sentinel, see the Sentinel Plug-ins SDK Web site.
