WSO2 CEP is shipped with JVM Metrics to monitor the CEP server performance using Java Metrics. The Java Metrics library consists of a variety of metrics that can be used for monitoring. With the WSO2 Carbon Metrics API, we have enabled all the metrics that are required to effectively monitor WSO2 products.
The WSO2 CEP 4.2.0 also provides the Event Metrics feature for the in-depth monitoring of throughput, latency, and memory usage of CEP.
The following sections provide a detailed description of how Carbon Metrics is used in CEP for monitoring.
