Pub/Sub Messaging Cache Counters
NCache offers a comprehensive set of performance counters that are specifically designed to track the statistics of Pub/Sub Topics in real-time. These counters are critical to ensuring the health of distributed messaging infrastructure and enable administrators to monitor message rates, expiration rates, and memory usage. You can use these counters to monitor your NCache instances using NCache Monitor or PerfMon tool.
