ProcDump is a Linux reimagining of the classic ProcDump tool from the Sysinternals suite of tools for Windows. ProcDump provides a convenient way for Linux developers to create core dumps of their application based on performance triggers.
Installation & Usage
- Minimum OS:
- Red Hat Enterprise Linux / CentOS 7
- Fedora 26
- Ubuntu 14.04 LTS
Checkout our install instructions for ditribution specific steps to install Procdump.
Build ProcDump from Scratch
To build from scratch you'll need to have a C compiler (supporting C11),
zlib, and a
make utility installed. Then simply run:
make make install
Building Procdump Packages
The distribution packages for Procdump for Linux are constructed utilizing
debbuild for Debian targets and
rpmbuild for Fedora targets.
To build a
deb package of Procdump on Ubuntu simply run:
make && make deb
To build a
rpm package of Procdump on Fedora simply run:
make && make rpm
Usage: procdump [OPTIONS...] TARGET OPTIONS -C CPU threshold at which to create a dump of the process from 0 to 100 * nCPU -c CPU threshold below which to create a dump of the process from 0 to 100 * nCPU -M Memory commit threshold in MB at which to create a dump -m Trigger when memory commit drops below specified MB value. -n Number of dumps to write before exiting -s Consecutive seconds before dump is written (default is 10) TARGET must be exactly one of these: -p pid of the process -w Name of the process executable
The following examples all target a process with pid == 1234
The following will create a core dump immediately.
sudo procdump -p 1234
The following will create 3 core dumps 10 seconds apart.
sudo procdump -n 3 -p 1234
The following will create 3 core dumps 5 seconds apart.
sudo procdump -n 3 -s 5 -p 1234
The following will create a core dump each time the process has CPU usage >= 65%, up to 3 times, with at least 10 seconds between each dump.
sudo procdump -C 65 -n 3 -p 1234
The following will create a core dump each time the process has CPU usage >= 65%, up to 3 times, with at least 5 seconds between each dump.
sudo procdump -C 65 -n 3 -s 5 -p 1234
The following will create a core dump when CPU usage is outside the range [10,65].
sudo procdump -c 10 -C 65 -p 1234
The following will create a core dump when CPU usage is >= 65% or memory usage is >= 100 MB.
sudo procdump -C 65 -M 100 -p 1234
All options can also be used with -w instead of -p. -w will wait for a process with the given name.
The following waits for a process named
my_application and creates a core dump immediately when it is found.
sudo procdump -w my_application
- Currently will only run on Linux Kernels version 3.5+
- Does not have full feature parity with Windows version of ProcDump, specifically, stay alive functionality, and custom performance counters
