Instructions
The CEE CEPA consists of applications that are designed to process SMB and NFS file and directory event notifications. Starting with Unity OE version 4.1, CEE CEPA also works on Unity. Some of the common uses for CEE CEPA include file auditing, centralized quota management, search/indexing, and as an enabler for other use cases such as RabbitMQ. An example of file auditing is logging an event any time a file or directory is created, renamed, or deleted. To configure CEE CEPA, CEE and a third-party file event software must be installed and configured in the environment.
There are three types of events that can be logged:
Pre Events Events are sent to the CEPA server for approval prior to being executed
Post Events Events are sent to the CEPA server after they occur for logging or auditing purposes
Post Error Events Error events are sent to the CEPA server after they occur for logging or auditing purposes
CEE CEPA must be enabled and an Event Publishing Pool must be created on the NAS Server, which defines the CEPA servers and the specific events that trigger notifications. This can be found in the Unity Unisphere from: NAS Server Properties >> Protection & Events >> Events Publishing page.
Once the NAS Server is configured, enable events publishing on the file systems that you want to receive events from. This can be done under the File System Properties >> Advanced tab. Depending on the type of file system, you can enable NFS and/or SMB events publishing. When a host generates an event on the file system over SMB or NFS, this information is forwarded to the CEPA server over an HTTP connection. The CEE CEPA software on the server receives and publishes this event, enabling it to be processed by the third party software. This enables the CEPA server to provide many additional services with information being sent from multiple systems.
You can have more details on the exact published events from Unity Unisphere Help by searching for "About Events Publishing" , where details of all events and the protocols implemented on are explicitly mentioned.
