Monitoring memory and caches

Complex distributed applications need end-to-end monitoring and management. Various application performance monitoring (APM) tools are available to proactively identify system glitches and bottlenecks. Apache Ignite offers APIs to enable, collect, and retrieve system performance. In this section, we'll take a look at the following two types of metrics:

• Memory region monitoring
• Cache monitoring

Memory region monitoring

The DataRegionMetrics interface is the gateway to Apache Ignite's memory region monitoring APIs. The first step to collect metrics is to enable it. The DataStorageMetrics interface provides methods to get metrics for data storage. The following Java code snippet enables...
