Diagnostic dump
Structured output captured during failure or termination, such as stack traces, core dumps, thread dumps, or runtime state snapshots.
Definition
A diagnostic dump is output captured during failure or termination that helps explain what the process was doing.
Depending on the system, a diagnostic dump might include:
- stack traces
- a core dump
- a thread dump
- runtime state summaries
Where you see it
Diagnostic dumps often appear on:
- crashes (
SIGSEGV,SIGABRT) - explicit requests to dump state (for example,
SIGQUITin some runtimes)
The exact content is runtime-specific.
