minidumper
Create process memory snapshots for debugging
SYNOPSIS
Typically requires kernel module + userspace program:
Module loaded into Kernel
`minidumper` -analyze
PARAMETERS
-analyze
Specifies the minidump file to analyze. The exact options will depend on the specific minidumper implementation.
-v
Enables verbose output, useful for debugging.
DESCRIPTION
The `minidumper` command isn't a standard, universally available Linux command. It refers to a tool or a kernel module used for creating and analyzing 'minidumps' or minimal core dumps. The idea behind it is to generate smaller core dumps than the full memory image, focusing only on the memory regions relevant to the crashing process, like stack and registers. This makes analysis faster and saves storage space.
The process typically involves a kernel module intercepting a crash signal (like SIGSEGV) and using predetermined rules or configurations to dump the necessary memory into a file. Another tool (often user-space) is used to parse this minidump file to get information about the crash.
The functionality of this tool can vary greatly depending on the specific implementation. It will often be developed to analyze crashes in embedded systems or within projects/companies needing specific crash reporting. Because it's often project-specific, you should review the documentation provided with the source code, or project in which the `minidumper` is being used.
CAVEATS
This command is not part of the standard Linux distributions. It's project-specific and will have varying features and configurations. There is no standard `minidumper` command documented in standard Linux manual pages.
USAGE
As the tool is custom developed, the specific usage depends entirely on the developer. Reviewing the source code and available documentation is essential. The minidump file produced needs to be parsed by an associated program, which this command (minidumper analyze
