Events publishing
CEE enables third-party applications to receive event information from the storage system upon accessing file systems.
The Common Event Enabler (CEE) provides an event publishing solution for PowerStore clients that allow third-party
applications to register and receive event notification and context from the storage system when accessing file systems.
Receiving event notification enables you to take event-driven actions on the storage to prevent security threats such as
ransomware or unauthorized access.
The CEE Common Events Publishing Agent (CEPA) consists of applications that are designed to process SMB and NFS files
and directory event notifications. The CEPA delivers both event notification and associated context to the application in one
message. Context can consist of file metadata or directory metadata that is needed for business policy decisions.
To enable CEE CEPA support, you must enable CEE CEPA and create an Event Publishing Pool on the NAS server.
An Event Publishing Pool defines the CEPA servers and the specific events that trigger notifications.
After configuring the NAS server, you can enable events publishing on the file system from which you want to receive events.
When a host generates an event on the file system over SMB or NFS, the information is forwarded to the CEPA server over
an HTTP connection. The CEE CEPA software on the server receives the event and publishes it, thus enabling the third-party
software to process it.
To use the Events Publishing Agent, it is required to have a PowerStore system with at least one NAS server configured on the
network.
For additional information about CEPA, which is part of the Common Event Enabler (CEE), see Using the Common Event
Enabler on Windows Platforms on

Create a publishing pool
Prerequisites
To create an event publishing pool, you must have an Events Publishing (CEPA) server FQDN.
About this task
An Event Publishing Pool defines the CEPA server and the specific events that trigger notifications. Define at least one of the
following event options:
● Pre Events - Events that are sent to the CEPA server for approval before processing.
● Post Events - Events that are sent to the CEPA server after they occur for logging or auditing purposes.
● Post Error Events - Error events that are sent to the CEPA server after they occur for logging or auditing purposes.
Steps
1. Select Storage > NAS Servers.
