Monitoring Config (monitoring.ncconf)
NCache is enriched with extensive features that boost your application performance. To ensure that NCache behaves exactly the way you want it to for utmost stability and performance, NCache provides a variety of monitoring counters. These counters are categorized as follows:
NCache Server Counters: Counters to monitor the stats of cache servers.
NCache Client Counters: Counters to monitor the stats of cache clients.
NCache Bridge Counters: Counters to monitor bridge and bridge caches.
NCache Distributed Cache with Persistence Counters: Counters to monitor NCache Distributed Cache with Persistence.
NCache Distributed Lucene with Persistence Counters: Counters to monitor NCache Distributed Lucene.
While monitoring NCache using the Prometheus tool, a metrics publisher is responsible for publishing counter stats on the NCache service. The decision of which counters will be published depends on the counters whose publishing is enabled. The monitoring.ncconf file shipped with NCache in the %NCHOME%\config file is used to configure the publishing of monitoring counters.
Note
You will find monitoring.ncconf at %NCHOME%\config in Windows or /opt/ncache/config in Linux.
