Cache Level Events

NCache event notifications let you design applications that react to various cache events. These notifications are disabled by default to save precious CPU and network resources. Events are fired upon addition, update and removal of an object or when cache is cleared. These notifications are off by default but can be turned on, for Clustered or Local Caches, as follows:

Using NCache Web Manager

• Launch NCache Web Manager by browsing to http://localhost:8251 or <server-ip>:8251 on Windows and Linux.

• In the left navigation bar, click on Clustered Caches or Local Caches, based on the cache to configure.

• Against the cache name, click on View Details.

• This opens up the detailed configuration page for the cache. Go to the Advanced Settings tab and click on Options in the left bar.

• Under Notifications, check the notifications you want to receive - OnItemAdded, OnItemAdded, OnItemUpdated.

• Click on Save Changes to apply this configuration to the cache.

Manually Editing NCache Configuration

Important

Make sure the cache is stopped before making any configuration changes.

• Specify cache-level notifications through config.ncconf by specifying the <cache-notifications> tag under the <cache-settings> tag:

 <cache-settings ...>
   <logging enable-logs="True" trace-errors="True" trace-notices="False" trace-warnings="False" trace-debug="False" log-path=""/>
</cache-settings>

• Once changes are made, start the cache and restart NCache service.
