Profiling Types - Atatus Docs

Different language runtimes support different profiling capabilities. Below is a breakdown of the profiling types available for each supported language.

Go

Profiling Type	Description
CPU Profiling	Measures CPU time spent in each function
Delay Profiling	Captures time spent waiting (e.g., on I/O or synchronization)
Lock Contentions	Measures time spent waiting to acquire locks
Goroutine Profiling	Captures the state of all goroutines
Allocation Space	Measures total memory allocated
Allocation Objects	Counts the total number of objects allocated
In-use Memory Space	Measures memory currently in use
In-use Objects	Counts objects currently in use
Samples	Number of stack samples collected

Node.js

Profiling Type	Description
CPU Profiling	Measures CPU time spent in each function
Wall	Measures wall-clock time (real elapsed time)
Timeline	Captures execution timeline for async operations
Samples	Number of stack samples collected
Space	Measures heap memory allocations
Objects	Counts heap-allocated objects

Java

Profiling Type	Description
CPU	Measures CPU time spent in each function
ALLOC	Tracks memory allocations
LOCK	Measures lock contention and wait times
WALL	Measures wall-clock time
CTIMER	CPU timer-based profiling
ITIMER	Interval timer-based profiling
