What are the primary NCache Event types?

NCache publishes three main event types: Information (general system updates), Warning (non-critical issues like nodes leaving), and Error (critical failures such as service start errors or licensing expiration).

Which Event ID indicates that an NCache cluster node has joined?

Event ID 1006 with the source 'NCache' and type 'Information' is published whenever a node successfully joins the cluster.

How can I monitor Split-brain events in NCache?

Monitor Event ID 1024 for the start of a Split-brain process and IDs 1027, 1028, and 1029 to track the status of the Split-brain merge process.

Cache Event IDs

NCache provides support to view Events in the Windows Event Log, enabling monitoring of distributed cache clusters. This allows tracking of all such Events through Windows Event Viewer or any tool that supports the Windows Event Logger. You can use these specific Event IDs to configure custom monitoring and automated alerting on your own end. These Event types are categorized as Information, Warning, and Error to assist in rapid troubleshooting and health diagnostics.
