![]() This metric accumulates memory retained by the most recent garbage collector run and allocated since then. Heap live size: The amount of memory considered live by the Go garbage collector.Idle memory can be returned to the operating system or retained by the Go runtime for later reassignment to the heap or stack. Heap idle size: The amount of memory not assigned to the heap or stack.Heap allocated Go objects count: The number of Go objects allocated on the Go heap.The Heap details tab digs deeper into the anatomy of the Go heap. Go stacks are used to execute Goroutines and grow dynamically. Stack: The amount of the memory used or committed to dynamic Go stacks.Overall: The sum of Heap, OffHeap, and Stack memory.Data structures used in the Go heap implementation are an example of OffHeap memory. OffHeap: The amount of the memory used or committed to Go runtime internal structures that are not allocated from heap memory.Heap: The amount of the memory used or committed to Go runtime heap.The Go managed memory tab breaks down memory metrics into various categories: Response latency: The average response time from the application to clients.Number of HTTP bad gateways: The number of responses that indicate invalid service responses produced by an application.Number of HTTP 5xx responses: The number of responses that indicate repeatedly crashing apps or response issues from applications.Total requests: The number of all requests representing the overall traffic flow.On the Go HTTP metrics tab, you can explore the following HTTP metrics: Goroutines: The number of Goroutines instantiated by the application and Go runtime infrastructure. ![]() Runtime heap: The amount of memory used or committed to the Go heap as well as Go garbage collection times.Suspension: The Go garbage collector percentage share compared to the overall application CPU time. ![]() The Go metrics tab provides an overview of the following important Golang metrics: ![]() The Go managed memory, Heap details, and Scheduling tabs-all accessible via the Further details tab-bring even more valuable insights into your Go-based application performance. The Go metrics and Go HTTP metrics tabs on the process overview page contain the most important Go-specific and HTTP metrics. Dynatrace OneAgent tracks numerous Go-related metrics. ![]()
