Re: [atomic-devel] How to handle crashes

[Jakub Filak <jfilak redhat com>]

I've created a Docker file that produces an image with ABRT configured to
detect Kernel oopses in systemd-journal, vmcores on host and registers
/proc/sys/kernel/core_pattern to detect core files:
https://github.com/jfilak/docker-abrt/tree/atomic_minimal

Detecting those problems is not a rocket science. However, with ABRT
employed you don't need to take care about this part and you can focus on
propagation of events to appropriate destinations.

Dominika, how can we teach ABRT to report the detected problems to
NodeProblemDetector?

Is there a command that ABRT can execute or should we connect to a TCP port?


Regards,
Jakub
