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.
NOTE:Sentinel 7.0 and later do not support legacy Collectors. When you run a legacy Collector, an error is displayed in the Status field of the Collector and the Collector does not start. You must use an equivalent JavaScript Collector, then move the legacy Collector event source nodes to the newly added JavaScript Collector.
