What kind of metrics does Dynatrace provide for heap management in Node.js?

Dynatrace provides heap and process metrics specifically designed to monitor the memory usage and performance characteristics of Node.js applications. These metrics include information such as heap size, memory allocation, and garbage collection activity, which are critical for understanding how a Node.js application uses memory over time.

Heap metrics allow developers to track the performance and efficiency of their memory management practices. By monitoring these metrics, they can identify memory leaks, excessive memory usage, and overall application performance related to memory handling. This is particularly important in Node.js environments, where improper memory management can lead to significant performance degradation and application crashes.

The other types of metrics mentioned—disk I/O, network bandwidth, and general application performance—serve different aspects of application monitoring and do not specifically focus on memory management within the Node.js context. While they may provide useful information, they do not delve into the nuances of heap usage and memory allocation that are critical for Node.js applications.
